There Used to be Nine Species of Human. What Happened to Them?

The disappearance of these other species resembles a mass extinction. But there’s no obvious environmental catastrophe, except for the rise of Homo Sapiens

There is a lot of imagination in anthropology. Take what you want from this, but remember, these theories will continue to evolve for some time.

The Conversation

Nine human species walked the Earth 300,000 years ago. Now there is just one. The Neanderthals, Homo Neanderthalensis, were stocky hunters adapted to Europe’s cold steppes. The related Denisovans inhabited Asia, while the more primitive Homo Erectus lived in Indonesia, and Homo Rhodesiensis in central Africa.

Several short, small-brained species survived alongside them: Homo Naledi in South Africa, Homo Luzonensis in the Philippines, Homo Floresiensis (“hobbits”) in Indonesia, and the mysterious Red Deer Cave People in China. Given how quickly we’re discovering new species, more are likely waiting to be found.

By 10,000 years ago, they were all gone. The disappearance of these other species resembles a mass extinction. But there’s no obvious environmental catastrophe – volcanic eruptions, climate change, asteroid impact – driving it. Instead, the extinctions’ timing suggests they were caused by the spread of a new species, evolving 260,000-350,000 years ago in Southern Africa: Homo sapiens.

Unless there was a global flood!

The spread of modern humans out of Africa has caused a sixth mass extinction, a greater than 40,000-year event extending from the disappearance of Ice Age mammals to the destruction of rainforests by civilisation today. 

But were other humans the first casualties?

We are a uniquely dangerous species. We hunted wooly mammoths, ground sloths and moas to extinction. We destroyed plains and forests for farming, modifying over half the planet’s land area. We altered the planet’s climate. But we are most dangerous to other human populations, because we compete for resources and land.

History is full of examples of people warring, displacing and wiping out other groups over territory, from Rome’s destruction of Carthage, to the American conquest of the West and the British colonisation of Australia. There have also been recent genocides and ethnic cleansing in Bosnia, Rwanda, Iraq, Darfur and Myanmar. Like language or tool use, a capacity for and tendency to engage in genocide is arguably an intrinsic, instinctive part of human nature. There’s little reason to think that early Homo sapiens were less territorial, less violent, less intolerant – less human.

History is full of examples of people warring, displacing and wiping out other groups over territory

Optimists have painted early hunter-gatherers as peaceful, noble savages, and have argued that our culture, not our nature, creates violence. But field studies, historical accounts, and archaeology all show that war in primitive cultures was intense, pervasive and lethal. Neolithic weapons such as clubs, spears, axes and bows, combined with guerrilla tactics like raids and ambushes, were devastatingly effective. Violence was the leading cause of death among men in these societies, and wars saw higher casualty levels per person than World Wars I and II.

Old bones and artefacts show this violence is ancient. The 9,000-year-old Kennewick Man, from North America, has a spear point embedded in his pelvis. The 10,000-year-old Nataruk site in Kenya documents the brutal massacre of at least 27 men, women, and children.

It’s unlikely that the other human species were much more peaceful. The existence of cooperative violence in male chimps suggests that war predates the evolution of humans. Neanderthal skeletons show patterns of trauma consistent with warfare. But sophisticated weapons likely gave Homo sapiens a military advantage. The arsenal of early Homo sapiens probably included projectile weapons like javelins and spear-throwers, throwing sticks and clubs.

Complex tools and culture would also have helped us efficiently harvest a wider range of animals and plants, feeding larger tribes, and giving our species a strategic advantage in numbers.

The ultimate weapon

But cave paintings, carvings, and musical instruments hint at something far more dangerous: a sophisticated capacity for abstract thought and communication. The ability to cooperate, plan, strategise, manipulate and deceive may have been our ultimate weapon.

The incompleteness of the fossil record makes it hard to test these ideas. But in Europe, the only place with a relatively complete archaeological record, fossils show that within a few thousand years of our arrival , Neanderthals vanished. Traces of Neanderthal DNA in some Eurasian people prove we didn’t just replace them after they went extinct. We met, and we mated.

Elsewhere, DNA tells of other encounters with archaic humans. East Asian, Polynesian and Australian groups have DNA from Denisovans. DNA from another species, possibly Homo erectus, occurs in many Asian people. African genomes show traces of DNA from yet another archaic species. The fact that we interbred with these other species proves that they disappeared only after encountering us.

But why would our ancestors wipe out their relatives, causing a mass extinction – or, perhaps more accurately, a mass genocide?

The answer lies in population growth. Humans reproduce exponentially, like all species. Unchecked, we historically doubled our numbers every 25 years. And once humans became cooperative hunters, we had no predators. Without predation controlling our numbers, and little family planning beyond delayed marriage and infanticide, populations grew to exploit the available resources.

Further growth, or food shortages caused by drought, harsh winters or overharvesting resources would inevitably lead tribes into conflict over food and foraging territory. Warfare became a check on population growth, perhaps the most important one.

Our elimination of other species probably wasn’t a planned, coordinated effort of the sort practised by civilisations, but a war of attrition. The end result, however, was just as final. Raid by raid, ambush by ambush, valley by valley, modern humans would have worn down their enemies and taken their land.

Yet the extinction of Neanderthals, at least, took a long time – thousands of years. This was partly because early Homo sapiens lacked the advantages of later conquering civilisations: large numbers, supported by farming, and epidemic diseases like smallpox, flu, and measles that devastated their opponents. But while Neanderthals lost the war, to hold on so long they must have fought and won many battles against us, suggesting a level of intelligence close to our own.

Today we look up at the stars and wonder if we’re alone in the universe. In fantasy and science fiction, we wonder what it might be like to meet other intelligent species, like us, but not us. It’s profoundly sad to think that we once did, and now, because of it, they’re gone.

Denisovans, Mysterious Human Relatives, Looked Just Like Us in At Least 1 Way

Rediscovery of missing finger bone shows slender fingertips
unlike knobby Neanderthal finger bones

Some human groups have more than five per cent Denisovan DNA

Emily Chung · CBC News 


Denisovans were originally identified from DNA in a bone from the base of the pinky finger of a young girl, shown above. Now the rest of that bone has been rediscovered, showing the entire bone is similar to that of modern humans and different from the fingertip of Neanderthals, which are more closely related to Denisovans.

They may have had huge, brutish-looking teeth, but Denisovans — ancient cousins of humans and Neanderthals — had slender, delicate fingertips like ours, a new study shows.

After rediscovering a missing piece of one of only five Denisovan fossils ever discovered, researchers from France, Russia and Canada digitally reconnected the two halves from the tip of the pinky finger from a Denisovan girl. 

The reconstruction showed it was indistinguishable from a human fingertip and different from the knobbed or clubbed fingertip bones of Neanderthals, they reported Wednesday in the journal Science Advances.

The finding is a small piece of the puzzle in figuring out who the mysterious Denisovans were, given that only five small fossils of the hominin species have ever been found.

"Until now, all we knew was how their teeth looked," said Bence Viola, a University of Toronto anthropologist who co-authored the paper. "All these little pieces allow us to build a picture of who the Denisovans were."

The new finding suggests researchers looking for Denisovan fossils might have to be more open-minded about what to look for, and that some fossils previously identified as modern humans may, in fact, be Denisovans, said Eva-Maria Geigl, an anthropologist at the Institut Jacques Monod at the Centre national de la recherche scientifique and the University of Paris who also co-authored the report.

More closely related to Neanderthals

Denisovans were first identified in 2010 as a new species of hominin using DNA extracted from the bottom half of the finger bone. Genetic analysis showed Denisovans were more closely related to Neanderthals than modern humans, but Denisovans interbred widely with modern humans, and some human groups have more than five per cent Denisovan DNA.


However, scientists know little about what they looked like, other than the fact they had massive molars similar to those of a more ancient hominin, Homo erectus.

Viola was a postdoctoral researcher at the lab Max Planck Institute for Evolutionary Anthropology in Leipzig that analyzed the DNA from the bone from the base of the fingertip. What the researchers didn't know at the time was that after the bone was excavated from Denisova Cave in Siberia in 2008, it was cut in half.

They only learned a couple of years ago that the other half had been sent to a different lab in the U.S. for analysis.

That half was subsequently photographed and measured by Geigl, who noticed that it had been cut. After she analyzed it genetically, she realized that it had exactly the same DNA as the bone that identified the Denisovans as a new species, and therefore must be part of the same bone.

But because the DNA analysis had already been published by the German researchers, and she was asked to return the bone to the U.S., she set the project aside.

2 halves reunited

Some years later, she said, she spoke to the Viola and the German researchers about the bone, which they didn't know about.

"It was a shock to us that somebody had the other half," Viola said in a phone interview from Kyrgyzstan, where he was doing field work.

Geigl offered to show the bone to them and suggested they find some way to publish the information.

"It's pity that nobody knows the no one knows that I'm the only one who has the pictures of this bone in my computer," she recalled telling them.

Viola was keen to see the photos, but quite surprised when he received them.

"This looks very different than what I expected," he recalled, writing in response.

The Denisovans had large, unusual teeth unlike those of humans or Neanderthals. (Bence Viola/University of Toronto)

Based on their huge teeth and a small fragment of skull, he had the impression Denisovans were even heftier and therefore less human-like than Neanderthals: "All of those are very large and robust. They come from huge individuals."

Geigl said the fact the bone looked more human than Neanderthal wasn't really a surprise for her. "Evolution is not something linear. Some features evolve faster than others."

The new finding suggests the knobs on the ends of Neanderthals' fingertips evolved relatively late.

Knobs on the fingertips suggest devolution, not evolution.

Viola combined the images of the two halves to reconstruct of the entire finger. That allowed the researchers to see that based on the growth of the bone, the girl it belonged to was likely a couple of years older than previously thought — about 14 or 15.

Matthew Tocheri, who holds a Canada Research Chair in Human Origins at Lakehead University in Thunder Bay, Ont., and was not involved in the study, said he thought the results were "kind of neat."

Like Geigl, he thought the similarity to humans was not that surprising. He noted modern humans, Neanderthals and Denisovans are all closely related, and, in fact, many Neanderthal and human features are indistinguishable. The fingertips just happen to be one difference.

Similarly, many Denisovans characteristics will likely be very human-like, and we don't yet know their "distinguishing" features, he said.

Tocheri said it was nice to have a bone that could be compared in modern humans, Denisovans and Neanderthals. But he added, "That's one bone out of over 200 elements to the skeleton. So we've got another 199 or so to go."

9.7mn-yo Ape Teeth Puzzle Scientists, Challenge Timeline of Human Species

Questionable Science

I love it when scientists discover that what they believe is completely wrong. Too much science, especially in the field of archaeology and paleontology, is not science at all but guess work and the consequence of highly over-active imaginations. And many scientists think Christians are stupid.

Ancient ape teeth dating back more than 9 million years and discovered in Germany last year are raising questions about the timeline of human evolution.

The two teeth, discovered in sediment of the Proto-Rhine River, are of an ape species whose remains have never before been observed in Europe.

Understood to belong to one ape, the two teeth are similar in structure to 3 million year old fragments belonging to an ape skeleton previously uncovered in Africa.

However, the German river bed remains, an upper right molar and left canine, predate the African example by more than 6 million years, according to a study published by the National History Museum Mainz.

The age disparity is puzzling since it raises questions over whether apes really originated in Africa.


While study author Herbert Lutz refused to be drawn on what it means for evolutionary theory, he said the findings indicate that there are still blind spots in the study of fossils.

“We want to hold back on speculation,” Lutz told Research Gate. “What these findings definitely show us is that the holes in our knowledge and in the fossil record are much bigger than previously thought.”

Not bigger than I previously thought! 

How the ape came to be in the Germany region near Eppelsheim is a “mystery,” Lutz said.

Maybe he was looking for a good beer, or a great glass of white wine? Schnitzel?

He added that if the ape is found to be related to the species observed in Africa 3 million years ago, then “[it] would mean that a group of primates was in Europe before they were in Africa.”

Science and Christianity - Who's Side is the Truth on?

University settles lawsuit with scientist fired after he found
soft tissue in dinosaur bones
By Chad Dou —

CSUN scientist Mark Armitage found soft tissue in a dinosaur bone, a discovery that throws significant doubt on evolution. Then, two weeks after publishing his findings, he was fired.

Now California State University at Northridge has paid Armitage a six-figure sum to settle his wrongful termination suit based on religious discrimination. While the university admits no wrongdoing, Armitage’s attorney said they feared losing a protracted lawsuit because of a “smoking gun” email that backed the plaintiff’s case.

The case of Armitage is the latest to show the mounting hostility Christians face in academics and other public arenas.


A Triceratops

“Soft tissue in dinosaur bones destroys ‘deep time.’ Dinosaur bones cannot be old if they’re full of soft tissue,” Armitage said in a YouTube video. “Deep time is the linchpin of evolution. If you don’t have deep time, you don’t have evolution. The whole discussion of evolution ends if you show that the earth is young. You can just erase evolution off the whiteboard because of soft tissue in dinosaur bones.”

Armitage was hired as a microscopist to manage CSUN’s electron and confocal microscope suite in 2010. He had published some 30 articles in scientific journals about his specialty.

A graduate of Liberty University, Armitage adheres to the “young earth” view,  against the majority of scientists who say our planet is 5 billion years old. He engaged students in his lab with Socratic dialogue over the issue of the earth’s age based on his and others’ research, he said.

In May 2012, Armitage went on a dinosaur dig at the famous fossil site of Hell Creek in Montana, where he unearthed the largest triceratops horn ever found there. Back at CSUN, he put the fossil under his microscope and made the startling discovery: unfossilized, undecayed tissue was present.

If the dinosaur were 65 million years old, the soft tissue could not have possibly remained, he says. His findings seconded groundbreaking discoveries by noted molecular paleontologist Mary Schweitzer, who triggered an earthquake in the world of paleontology when she published about soft tissue in dinosaur bones in 2005. (Schweitzer subsequently postulated that iron is responsible for preserving the soft tissue.)

Armitage’s February 2013 study was published in the peer-reviewed Acta Histochemica, a journal of cell and tissue research. Two week later, he found himself without a job.

A biology professor had come into his office and said, “We are not going to tolerate your religion in this department.”

Armitage fought back. Professors and students alike had praised his work managing the microscope lab. His suit alleged he was excluded from a secret meetings of the microscopy committee. In a “smoking gun” email, university officials suggested they could ease Armitage out of his part-time position by making it full-time, Reinach said.

A colleague described the process as a “witch hunt,” according to Inside Higher Ed.

For two years, CSUN fought Armitage’s lawsuit. The university alleged his firing was simply a restructuring of their biology department and not a case of religious discrimination. But CSUN lost its bid to have the judge summarily throw the case out of court as groundless in July of last year.

So CSUN settled with Armitage for $399,500 in 2016, according to Inside Higher Ed.

Alan Reinach, Armitage’s attorney, hailed the settlement as precedent-setting.

“We are not aware of any other cases where a creationist received a favorable outcome,” said Reinach, executive director of the Church State Council, a nonprofit California public interest legal organization. “This was truly a historic case.”

CSUN has downplayed its decision to settle, saying in a statement that the university is committed to religious freedom and freedom of speech.

“The Superior Court did not rule on the merits of Mr. Armitage’s complaint, and this voluntary settlement is not an indication of wrong-doing,” according to a CSUN statement published in Retraction Watch. “The decision to settle was based on a desire to avoid the costs involved in a protracted legal battle, including manpower, time and state dollars.”

But Reinach countered: “They certainly would not have paid that kind of money if they did not recognize that we had them dead to rights. The state doesn’t put large, six-figure settlement money out unless they are really concerned they are going to lose.”

Prior to looking for soft tissue in dinosaur bones, Armitage studied diatoms, unicellular organisms that make up phytoplankton, which reveal a dizzying complexity and organization at the microscopic level.

According to Armitage, the beauty and complexity of diatoms lends credence to the idea they are a product of a Creator and not of spontaneous evolution.

“Evolution is structure supported by two pillars: one is chance, and the other is time. Chance is required because we obviously can’t say that a thinking force created life on earth. That is anathema for the materialists. If you kick out one of those two pillars the whole structure collapses,” Armitage noted. “If you kick out chance by showing incredible design, the structure of evolution starts to totter and it may crash. Because you cannot have design in a world that doesn’t have a Designer.

“The other pillar is time because you cannot get a man from a frog unless the princess kissed the frog. That’s a fairy tale. So in science you have to have deep time to get evolution.”

Subsequent to the controversy, Armitage has been on additional digs and found more soft tissue but is finding it difficult to get published. “I’m clearly being blackballed,” he said in The College Fix.

“Soft tissue in dinosaur bones destroys deep time.” Armitage said. “Dinosaur bones cannot be old if they’re full of soft tissue.”

The Evolution of Islam Continues in Turkey, Darwin - Not So Much


Turkey to scrap Darwin’s ‘controversial & redundant’ theory of evolution from schoolbooks

Charles Darwin © Wikipedia

Turkey is set to drop the “controversial” theory of evolution from the high school curriculum to better reflect local and national values, making it the second predominantly Muslim country after Saudi Arabia to not teach students Darwin’s theory.

Educators in Turkey argue that Charles Darwin’s theory is too complex for teenagers to understand and that they should wait until they enter college to be able to comprehend and discuss secular scientific discourse. Starting from the 2019 school year, biology textbooks will, therefore, ditch a national curriculum chapter about the concept.

“We have excluded controversial subjects for students at an age unable yet to understand the issues’ scientific background. As the students at ninth grade are not endowed with antecedents to discuss the ‘Origin of Life and Evolution’ section in biology classes, this section will be delayed until undergraduate study,” head of the Education Ministry’s curriculum board, Alpaslan Durmus revealed this week, according to Hurriyet Daily. 

Does everyone in Turkey actually reach undergraduate studies?

He added the new curriculum reflects the “local and national values” of Turkish society. The decision to drop Darwin got the thumbs up from the Turkish President, Recep Tayyip Erdogan.

“We made the simplification of redundancies. Elements inappropriate to our values have been removed,” Durmus noted, as quoted by Turkish language Cumhuriyet. 

Durmus also pointed out that “Religion and Morality” classes, which are now obligatory, would not be taught to first, fifth, and ninth graders unless they choose to take it.

The decision to ditch Darwin's theory came after a fierce debate on the issue. Since January, universities and academics have argued that evolution should be taught starting from fifth grade.

“The subjects of Science and Technology classes in elementary schools should be presented with a perspective that allows students to connect it to subjects they will encounter in future years. It should provide them with an evolutionary point of view,” the academics argued, according to Hurriyet.


Becoming more and more Islamic

Some Turkish publications suggested that the change reflects the overall effort by the government to reduce the influence of secularism introduced by Mustafa Kemal Ataturk, the founder of modern Turkey.

The theory of evolution, first revealed in the 1859 book ‘On the Origin of Species’, argues that life evolved through a natural selection, a process where organisms change over time because of heritable physical or behavioral traits.

In most countries in the Middle East and North, evolution and creationist theories are taught side-by-side. In the most extreme case, Saudi Arabia’s school education makes no mention of evolution besides a brief reference to it as a blasphemous theory. On the contrary, Iran teaches evolution as a crucial part of the school biology curriculum from 5th grade.

Becoming more and more like Saudi Arabia with its Salafist bent cannot be a good thing either for Turkey or anywhere else in the world.

According to an article titled ‘Islamic Theological Views on Darwinian Evolution’ published in Oxford Research Encyclopedia of Religion, Muslim scholars remain split on the acceptance or rejection of Darwin’s theory. 

The so-called ‘rejectionist’ camp argues that evolution is “totally contradictory and incompatible with a literal reading of Islamic teachings.” The ‘pro-evolutionist’ camp, in turn is split into two factions, those who entirely embrace the scientific theory and those who argue that “some but not all aspects” can be accommodated by Islam.

‘The Darwinian View is False’: Ph.D. Biologist Dismantles Evolution in New Book

Photo Credit: YouTube

By Garrett Haley

An accomplished molecular biologist with more than two decades of research experience has come out with a new book in which he describes crippling weaknesses in the theory of evolution and argues instead that life must have been invented by God.

Dr. Douglas Axe is a credentialed scientist who earned a Ph.D. from California Institute of Technology and held a number of research positions at the University of Cambridge. The author of numerous scientific papers, Axe currently serves as director of Biologic Institute—a non-profit organization committed to researching biology and the origin of life.

Image result for DNA

Axe says he first became interested in evolution while working on his Ph.D. in California, so at Cambridge he extensively studied DNA and proteins.

“[My strategy was] to look at the constraints on gene sequences and protein sequences and see if the constraints were loose enough that evolution could work or if they were too tight so that evolution couldn’t work,” Axe said in a recent interview with the Discovery Institute.

While conducting his research at Cambridge, Axe began to doubt the validity of Darwin’s ideas.

“I was consistently starting to find that [the constraints on gene and protein sequences] were too tight—that the target that had to be hit for something to work as an enzyme was too small for accidental changes, accidental mutations,” he said.

Axe decided that Darwin’s natural selection observations were valid and scientifically sound. However, based on his research, he concluded that evolutionary processes are unable to create new species and life forms.

“That’s where Darwin went wrong,” Axe stated. “He assumed that inventions could [take place] a little bit at a time.”

Charles Darwin
“It’s easy to fall for the idea that on a scale of eons and on a scale of billions and trillions of organisms, things can happen that are very, very counterintuitive,” he explained. “Well, it turns out, if you do the math, billions of years is not nearly long enough and trillions and trillions of organisms is not nearly enough for the sort of magic to happen that would have to happen for inventions to happen by accident. It’s just not enough.”

To further explain his findings, Axe, who now describes himself as “a Darwin-doubter,” has written a book that describes the pitfalls of evolutionary thinking. The book, “Undeniable: How Biology Confirms Our Intuition That Life is Designed,” was published this summer.

He hopes the book will dismantle the idea that doubting evolution equals ignorance.

“The orthodox position in the academies is that Darwinism is true and everyone who denies it is putting their head in the sand,” he said in an interview with “The Mountain Times.” “It’s not easy to dislodge that, but my plan is to get a huge number of people who are very bright and very capable of articulating their point of view, who get this.”

Contrary to what many think, Axe says, science clearly points to a Creator.

“The technical science shows that design is true, that design is the true understanding of life, and that the accidental view—the Darwinian view—is false,” Axe stated in a Discovery Institute presentation. “Our intuitions say the same thing, and I think it’s remarkable that the two agree so well.”

How Old is the Earth, Really? Why Judaism Rejects Creationism

By Adam Eliyahu Berkowitz

“Before the mountains were brought forth, or ever Thou hadst formed the earth and the world, even from everlasting to everlasting, Thou art God.” Psalms 90:2 (The Israel Bible™)

After successfully debating Bill Nye, a celebrity scientist, Ken Ham built a $92 million theme park in Kentucky with a full-size replica of Noah’s Ark as a centerpiece to promote his belief in Biblical Creationism. People are flocking to the park, and its Biblical message of creation seems to be gaining popularity. This belief has not caught on in Judaism, but the reasons may surprise you.

A Pew poll in February showed that 34 percent of Americans choose creationism over evolution, and another 25 percent believe in evolution guided by a supreme being (intelligent design). The poll went into detail, showing that 57 percent of Evangelical Christians believe in creationism, with another 25 percent believing in natural processes guided by a supreme being, leaving only 11 percent who believe in evolution.

On the other hand, the Pew poll showed that 58 percent of Jews believed the world came about through natural processes, another 18 percent believed these processes were guided by a supreme being, and only 16 percent believed the world has always existed in its present form.

It may seem paradoxical that the People of the Book, who received the Torah directly from God, would reject a belief based on a literal reading of the Bible. But although many see creationism as a choice of belief and Bible over science and data, Jews have worked hard to live successfully in both worlds.

In its purest form, creationism understands the world as coming into existence, fully formed, in six calendar days of 24 hours each, with man created separately as the pinnacle of God’s work. It precludes evolutionary theory and theories about the origin of the universe, leading to a conflict on estimates of when the earth and the universe were created.

Scientists generally agree the earth was formed 4.5 billion years ago. Most scientists claim the Big Bang that brought the universe into existence occurred approximately 14 billion years ago. Young Earth creationists believe both events occurred simultaneously between 6,000 and 10,000 years ago.

As director of the Biblical Museum of Natural History, Rabbi Natan Slifkin embodies the ideal of a Biblical scientist. He doesn’t see any contradictions between the worlds of Bible and science. Judaism, he explains, has always been able to accommodate science and theology. He quoted the Rambam, a preeminent medieval Sephardic Jewish philosopher.

“As Rambam said, accept the truth from wherever it comes,” he told Breaking Israel News.

“According to the rationalist approach, it is preferable to explain creation in scientific terms, because it is always preferable to see God working within nature and a system of law. “

Conflicts do arise between Torah and science. The Hebrew calendar, presently standing at 5776, is, in theory, based on the creation of the world. Rabbi Slifkin again quoted the Rambam’s Guide to the Perplexed, in which the rabbinical scholar wrote, “The account of creation is not all to be taken literally.”

The Rambam went on to explain that the Six Days represent a conceptual rather than historical account of creation. Rabbi Slifkin cited Rabbi Dovid Tzvi Hoffman (1843-1921), a member of Agudath Israel’s Council of Torah Sages, who suggested that the Six Days of Creation were lengthy eras rather than 24-hour periods.

Evolution, the impetus for Ken Ham’s massive Biblical theme park, simply does not seem to be such a big deal for Jewish Biblical scholars.

“God can work through meteorology, through medicine, through history, and through developmental biology. This is why it makes no difference if the neo-Darwinian explanation of the mechanism for evolution is true or not,” Rabbi Slifkin explained. “All these descriptions were interpreted literally by the Sages of old, and yet almost all recent Torah scholars interpret them non-literally.”

Torah Judaism also differs from Bible-based Christian creationism on the point of the nature of man. Creationism holds that man is distinct from animals, owing to the separate description of his being “formed”. It is partly for this reason that creationists reject evolutionary theory.

Then Hashem God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul. Genesis 2:7

Genesis describes man’s creation twice, and Rabbi Slifkin emphasized the version in the first chapter of Genesis.

And God created man in His own image, in the image of God created He him; male and female created He them. Genesis 1:27

Professor Natan Aviezer
Bar Ilan University
“Classical Judaism has long maintained that man is not qualitatively different from animals in his physical aspects,” the rabbi noted. “Man’s unique identity is in his spiritual soul, not in his physical body and most certainly not in his physical origin.”

Professor Natan Aviezer of Bar Ilan University, a physicist and religious Jew, deals with this issue in his book Modern Science and Ancient Faith. He quotes Charles Darwin’s parting words in his manifesto on evolution, On the Origin of Species.

“There is a grandeur in this view of life, having been originally breathed by the Creator into a few forms or into one, and from so simple a beginning, endless forms most beautiful and most wonderful have been and are being evolved.” Charles Darwin

Aviezer also cites Samson Raphael Hirsch, an influential German rabbi and contemporary of Darwin, bringing a Rabbinic concept of Olam Ke’Minhago Noheg (the universe goes its accustomed way). God did not simply create the world and step back. Aviezer explains that God works within nature.

“This important principle explains how God interacts with His world,” wrote Professor Aviezer in his book. “It follows from this principle that no scientific discovery can cast doubt on the existence of God.”

Was Charles Darwin Psychotic? A Study of His Mental Health

by Jerry Bergman, Ph.D.



Darwin's many lifelong and serious illnesses have been the subject of much speculation and study for over a century. Darwin stated that his health problems began as early as 1825 when he was only sixteen years old, and became incapacitating around age 28 (Barloon and Noyes, 1997, p. 138). Horan (1979, p. ix) concluded that Darwin was "ill and reclusively confined to his home in Kent for forty years." Darwinian scholar Michael Ruse even concluded that "Darwin himself was an invalid from the age of 30" (2003, p. 1523). And medical doctor George Pickering, in an extensive study of Darwin's illness, concluded that in his early thirties, Darwin became an "invalid recluse" (1974, p. 34). UCLA School of Medicine Professor Dr. Robert Pasnau (1990, p. 123) noted that Darwin also "remained ill almost continually" for the entire five years that he was on his HMS Beagle trip.

Dozens of scholarly articles and at least three books have been penned on the question of Darwin's illness. The current conclusion is that Darwin suffered from several serious and incapacitating psychiatric disorders, including agoraphobia. Agoraphobia is characterized by fear of panic attacks (or actual panic attacks) when not in a psychologically safe environment, such as at home. Darwin, as is common among agoraphobiacs, also developed many additional phobias—being in crowds, being alone, or leaving home unless accompanied by his wife (Kaplan and Sadock, 1990, pp. 958-959).

Agoraphobia is also frequently associated with depersonalization (a feeling of being detached from, and outside of, one's own body), a malady that Darwin also suffered (Barloon and Noyes, 1997, p. 138). A study of Darwin's mental condition by Barloon and Noyes concluded that Darwin suffered from anxiety disorders that so severely impaired his functioning that it limited his ability to leave his home, even just to meet with colleagues or other friends. This diagnosis likely explains his very secluded, hermit-like lifestyle (1997, p. 138). It also helps to explain the title of Desmond and Moore's 1991 biography of Darwin: Darwin: The Life of a Tormented Evolutionist.

Other Psychiatric and Medical Problems

Colp (1977, p. 97) concluded that "much of Darwin's daily life was lived on a rack which consisted of fluctuating degrees of pain" that was sometimes so severe that Darwin called it "distressingly great." Darwin's many psychological or psychologically influenced physical health symptoms included severe depression, insomnia, hysterical crying, dying sensations, shaking, fainting spells, muscle twitches, shortness of breath, trembling, nausea, vomiting, severe anxiety, depersonalization, seeing spots, treading on air and vision, and other visual hallucinations (Barloon and Noyes, 1997, p. 139; Picover, 1998, p. 290; Colp, 1977, p. 97; Bean, 1978, p. 573). The physical symptoms included headaches, cardiac palpitations, ringing in ears (possibly tinnitus), painful flatulence, and gastric upsets—all of which commonly have a psychological origin (Pasnau, 1990). Colp noted that "behind these symptoms there was always a core of anxiety and depression" (1977, p. 97). Some speculate that part of Darwin's mental problems were due to his nagging, gnawing fear that he had devoted his "life to a fantasy"—and a "dangerous one" at that (Desmond and Moore, 1991, p. 477). This fear was that his theory was false and there was, in fact, a divine Creator.

Darwin's behavior also indicates that he suffered from a mental disorder. Although devoted to his wife and daughters, he "treated them as children" even after his daughters were fully grown (Picover, 1998, p. 289). Some of Darwin's statements to others also cast doubt on his mental stability. For example, in 1875 he wrote the following words to fellow scientist Robert Hooker:

You ask about my book, & all that I can say is that I am ready to commit suicide: I thought it was decently written, but find so much wants rewriting. . . . I begin to think that every one who publishes a book is a fool (quoted in Colp, 1977, p. 228).

Colp noted that Darwin's son Leonard claimed that his father's illness even interfered with his feelings for his children. For example, Leonard once noted that

As a young lad I went up to my father when strolling about the lawn, and he . . . turned away as if quite incapable of carrying on any conversation. Then there suddenly shot through my mind the conviction that he wished he was no longer alive (quoted in Colp, 1977, p. 100).

Darwin's mental problems were considered so severe that Picover (1998, p. 289) included Darwin in his collection of historical persons that he calls "strange brains . . . eccentric scientists, and madmen." That Darwin suffered from several severely disabling maladies is not debated; the only debate is what caused them (Pasnau, 1990, p. 121).

Other Possible Causes of Darwin's Condition

Others, including Darwin's own wife, argued that his mental problem stemmed from guilt over his life's goal to refute the argument for God from design (Bean, 1978,
p. 574; p. 28; Pasnau, 1990, p. 126). Most of the psychoanalytic studies have argued that his problems were a result of his repressed anger toward his tyrannical father and "the slaying of his heavenly father" by his theory (Pasnau, 1990, p. 122).

Diagnosis of the cause of Darwin's mental and physical disorders include parasitic disease (Chaga's disease—caused by an insect common in South America), arsenic poisoning, and possibly even an inner ear disorder (Picover, 1998, p. 290; Pasnau, 1990). All of these causes have largely been refuted. Many persons conclude he had a classic, essential mental disturbance bordering on psychosis (a severe, incapacitating mental disorder). Regardless of the diagnosis, Darwin's condition was clearly incapacitating, often for months at a time, and rendered him an invalid for much of his life, especially in the prime of his life.

Arnold Sorsby concluded that Darwin was also an obsessive-compulsive and gives the following evidence:

If Chagas's disease did not cause Darwin's symptoms what did? My personal diagnosis would be an anxiety state with obsessive features and psychosomatic manifestations. Anxiety clearly precipitated much of his physical trouble, and regarding the obsessive component there are several important points. . . .

Darwin exhibited the obsessional's trait of having everything "just so"; he kept meticulous records of his health and symptoms like many obsessional hypochondriacs. Everything had to be in its place; he even had a special drawer for the sponge which he used in bathing . . . Then there is the health diary he kept. Days and nights were given a score according to how good they were; the score was added up at the end of each week, and there is evidence of frequent changing of mind in deciding whether a night was very good or just good (1974, p. 228).

Darwin's Own Words about His Condition

In addition to the diary on his health problems and complaints (Colp, 1977, p. 136), he frequently discussed his health problems in his letters and his autobiography. Darwin's own description of his condition included the following: "I am forced to live, . . . very quietly and am able to see scarcely anybody and cannot even talk long with my nearest relations" (quoted in Bowlby, 1990, p. 240). Darwin once complained that speaking for only "a few minutes" to the Linnean Society "brought on 24 hours vomiting" (Darwin, 1994, pp. 98-99). At another time, Darwin had a "house full of guests" and after he visited the parish church for a christening, he was "back to square one" and his good health "had vanished `like a flash of lightning'" and sickness (including the vomiting) returned (Desmond and Moore, 1991, p. 456). The suddenness of his illness, as illustrated by these incidents, indicates that his incapacitating episodes were psychological in origin.

Another side of Darwin revealed his sadistic impulses. His own words taken from his autobiography give a vivid example:

In the latter part of my school life I became passionately fond of shooting, and I do not believe that anyone could have shown more zeal for the most holy cause than I did for shooting birds. How well I remember killing my first snipe, and my excitement was so great that I had much difficulty in reloading my gun from the trembling of my hands. This taste long continued and I became a very good shot (1958, p. 44).

The fact that he loved killing so much that killing his first bird caused him to tremble with excitement could certainly indicate a sadistic streak in Darwin. His passion for killing birds is well known. One wonders if this "passion" for killing may have, in part, motivated his ruthless "survival of the fittest" tooth and claw theory of natural selection.

Conclusions

Darwin was clearly a very troubled man and suffered from severe emotional problems for most of his adult life, especially when he was in the prime of life. The exact cause of his mental and many physical problems has been much debated and may never be known for certain. Since Darwin wrote extensively about his mental and physical problems, we have much material on which to base a reasonable conclusion about this area of his life. The diagnosis of the cause of his mental and physical problems includes a variety of debilitating conditions, but agoraphobia with the addition of psychoneurosis is most probably correct.

Unfortunately, most writers have shied away from this topic, partly because Darwin is now idolized by many scientists and others. Often listed as one of the greatest scientists of the nineteenth century, if not the greatest scientist that ever lived, Darwin is one of the few scientists known to most Americans. To understand Darwin as a person and his motivations, one must consider his mental condition and how it affected his work and conclusions.

There is a lot of interesting stuff here. For instance, Darwin's attitude toward his father probably reflected his attitude toward his Heavenly Father. There is a tendency to blame God when our lives are very difficult and unhappy. Then there is also a tendency to reject any belief in God for allowing such suffering. If Darwin suffered from one or both of these attitudes, it may explain his motivation for writing On the Origin of Species.

There is another possibility that I want to discuss very carefully. I have known people with some of the psychological symptoms Darwin suffered from. I have seen people shaking from fear, and I have seen people who were about to lose their jobs because they couldn't summon the courage to leave their house. I have also seen such people immediately relieved of these fears and anxieties after I prayed for them and rebuked any evil spirits that afflicted them. 

Was Darwin demonically afflicted? Probably not! But in my mind it's a possibility, especially when you consider his response to attending a Christening at a church.

It Feels Like a 'Crime' to Be Christian in Pakistan

There are no angels in Islamabad; only politicians

The deplorable state of Christians in Pakistan
by WAJAHAT S. KHAN

A splinter group of the Pakistani Taliban claimed responsibility for an Easter Sunday suicide attack on a park in Lahore and said Christians were "our prime target." In August 2014, NBC News examined what life is like for Christians in the country.

ISLAMABAD, Pakistan This Islamic republic's wealthy and cosmopolitan capital is jokingly referred to as "a beautiful city 15 minutes from Pakistan." But life is no laughing matter for Islamabad's Christian community.

Most of the city's Christians can be found living in ramshackle houses constructed over open sewers in ghettos hidden from sight behind whitewashed walls. Authorities supply no power or gas to the slums, which are essentially cities within cities and in some cases are nestled between Islamabad's most plush neighborhoods.

Pakistan's founder Mohammad Ali Jinnah proclaimed in 1947 that his countrymen "may belong to any religion or caste or creed — that has nothing to do with the business of the state."


But the modern reality is very different. Most people in Pakistan are Muslims and Jinnah's imagined secular state has become increasingly theocratic after decades of dictatorships and official Islamism. 

This, I believe is typical evolution in an Islamic state. They tend toward theocracy and away from secularism. Look at Turkey, an intensely secular country when Attaturk separated it from the Ottomans a century ago. Now look at it! Erdogan is not so far from setting himself up as Sultan.

Europeans don't get this evolution. Many countries still think they can absorb an endless number of Muslims and maintain there western identity. They are fooling themselves and putting themselves in a position from which they can never extract themselves. Europe is living on borrowed time.

Christians, particularly the poor belonging to the agricultural center and north of the country, are considered outcasts by many and find themselves pushed to the edge of society.

Islamabad's Christians allege rampant discrimination by the conservative Pakistan Muslim League government. They say their small proportion of the population means they don't stand a chance at the ballot box and are now demanding a voice.


Recently retired cook Rehmat Masih has lived in Islamabad for four decades. The 65-year-old offers a bleak assessment of life in a Christian slum.

"I think being Christian, in this place, this Pakistan, is a crime," he said. "If we speak out, our corpses will be on the road."

Masih lives in "100 Quarters," a litter-strewn slum tucked between Islamabad's posh Margalla and Hill Roads. It is named after the first 100 apartments granted to Christians by the government in the 1960s, but it has since grown and now houses more than 1,000 Christian families.

"They say that Islamabad is a great capital of a great nation," said Masih, standing next to an overflowing drain. "But they let us live like this in middle of Islamabad. Officials drive by every day in BMWs and see this. Yet we are kept like this. Why?"


"WE ARE TOO SCATTERED, TOO DIVIDED, TOO UNEDUCATED"

According to the National Minority Alliance (NMA), Christians form under three percent of Pakistan's estimated 180 million people. But the community is spread all over the country, making it almost impossible for Christians to elect representatives who share their religion because they lack the numbers in a free-for-all poll. Almost always faced with a choice of a Muslim candidate from mainstream parties, they have to depend on a handful of "reserved" seats for minorities for representation in the 343-seat parliament, where non-Muslim minorities — Hindus, Sikhs, Parsis and Christians — have only 10 seats.

Critics like Samuel Yaqoob, of the Muslim-Christian Coalition, say those seats are given to "friends and favorites of the ruling parties, not actual spokespersons of our community."

"We are too scattered, too divided, too uneducated," added Robin Daniel, of the National Minority Alliance.

Many residents of the capital's Christian slums work in sanitation, cleaning sewers and collecting refuse. Others provide domestic help for Islamabad's well-heeled. Students from private high schools can be spotted with their expensive cars parked near the gates of such slums during afternoons, purchasing narcotics from Christian teenagers.

"Our problems are social, legal and political," said Shahryar Shams, 25, a newly graduated lawyer. "In theory, all fundamental rights for minorities are granted by the Constitution of Pakistan. But we lack organized political leadership in our own community. We face increasing extremism from the rest of society too ... But our biggest issue is that we are represented by those who are selected by the powers that be, and not through our direct vote."

In September, a suicide bomb attack on a church killed at least 75 people. And in March 2013, a Muslim mob set ablaze almost 200 buildings in a predominantly Christian neighborhood of Lahore.

Pakistan's much-debated "Blasphemy Law" is also often used to target Christians and other minorities. In 2012, 14-year-old Rimsha Masih was falsely accused of burning the Quran, the sacred Islamic text. Charges were later dropped amid international concern for her safety, but the law, remains on the books. Those accused under an anti-blasphemy law are sometimes lynched by the public even if they are found innocent by the courts.

One brave politician championed the idea of dropping the grossly misused Blasphemy Laws. He was murdered last year by the religion of peace.

But Fazeela Bibi, 17, a Christian high-school dropout who works as an office assistant at the American Embassy in Islamabad, suggested that the community was traditionally "not united" enough to drive change.

"One person can't do anything alone," she said, while preparing lunch over a wood stove in a 100 Quarters courtyard adjacent to a drain oozing out monsoon rains and refuse. "Injustice cannot be fought alone."

Fazeela Bibi, a 17-year-old resident of the "100 Quarters" slum, says Christians are unfairly treated in Pakistan but also acknowledges that the community is not organized. Wajahat S. Khan / NBC News
Masih, the retired cook, has been unsuccessfully trying for 14 months to meet his elected local representative to request repairs for a broken electric transformer. He wasn't too optimistic about the future.

"I'm pretty sure that we will remain living like this," he said. "That's how it's been for 67 years. There are no angels in Islamabad. Only politicians."

Complex Human DNA Trail Provides Some Interesting Surprises

Neanderthals & humans interbred 100,000 years ago
At least 5 different species of humans found
By Rebecca Morelle, Science Correspondent, BBC News

Neanderthals may have been breeding with modern humans much earlier than was thought

Traces of human DNA found in a Neanderthal genome suggest that we started mixing with our now-extinct relatives 100,000 years ago.

Previously it had been thought that the two species first encountered each other when modern humans left Africa, about 60,000 years ago.

The research is published in the journal Nature.

Dr Sergi Castellano, from the Max Planck Institute for Evolutionary Anthropology, in Germany, said: "It is significant for understanding the history of modern humans and Neanderthals."

The Neanderthal remains were found in a cave in Siberia copyright BENCE VIOLA

The ancient remains of a female Neanderthal, found in a remote cave in the Altai Mountains in Siberia, are the source of these revelations about the sex lives of our ancestors.

A genetic analysis reveals that portions of human DNA lie within her genome, revealing an interspecies mingling that took place 100,000 years ago.

We really don't know how widespread Neanderthals and early modern 
humans might have been in the regions between Arabia and China at this time

Prof Chris Stringer, Natural History Museum

Earlier research suggested that humans started interbreeding with our heavy-browed, stocky relatives when they migrated out of Africa and began to spread around the world.

As they left the continent, they met - and mingled with - the Neanderthals, who lived across Europe and Asia.

Neanderthal genes from these encounters are found in humans today, and recent studies have shown that these portions of DNA play an integral role in everything from our immune system to our propensity to diseases.

But the latest finding of a flow of genes in the opposite direction, from humans to Neanderthals, suggests such mating was happening thousands of years earlier.

It is not yet clear what impact these genes had on Neanderthals. "The functional significance of this is unclear at the moment," said Dr Castellano.

However, the findings do shed more light on the history of human migration.

At the moment we simply don't know how these matings happened
Prof Chris Stringer, Natural History Museum

If early humans were having sex with Neanderthals 100,000 years ago, then they must have been doing so outside of Africa because our close relatives were not found there. And this means that they had left Africa before the larger dispersal that took place at least 40,000 years later.

This adds to the idea that early forays out of the continent took place. Other recent evidence includes early human fossils found in Skhul and Qafzeh in Israel, and recent research that suggests people were living in China at least 80,000 years ago.

Commenting on the study Prof Chris Stringer, research leader in human origins, from the Natural History Museum in London, said: "I think that anywhere in southern Asia could theoretically have been the location of this early interbreeding, since we really don't know how widespread Neanderthals and early modern humans might have been in the regions between Arabia and China at this time."

He added: "At the moment we simply don't know how these matings happened and the possibilities range from relatively peaceful exchanges of partners, to one group raiding another and stealing females (which happens in chimps and some modern hunter-gatherers), through to adopting abandoned or orphaned babies.

"Eventually, geneticists should be able to show if the transfer of DNA in either direction was mainly via males, females, or about equal in proportion, but it will need a lot more data before that becomes possible."

Altai Mtns, Siberia/Mongolia

The cave in the Altai Mountains of Siberian in the photo above is actually famous for having housed not only Neanderthals and humans, but also another extinct species called Denisovans. Their history just adds a whole nuther level of confusion to the human genome. This from Wikipedia:

Denisovan or Denisova hominin (pronunciation: /dᵻˈniːsəvə/ dɛ-nee-sə-və) is an extinct species of human in the genus Homo. The species is sometimes given the name Homo sp. Altai, and Homo sapiens ssp. Denisova. In March 2010, scientists announced the discovery of a finger bone fragment of a juvenile female who lived about 41,000 years ago, found in the remote Denisova Cave in the Altai Mountains in Siberia, a cave which has also been inhabited by Neanderthals and modern humans. Two teeth belonging to different members of the same population have since been reported. In November 2015, a tooth fossil containing DNA was reported to have been found and studied.

Genetically distinct DNA

Analysis of the mitochondrial DNA (mtDNA) of the finger bone showed it to be genetically distinct from the mtDNAs of Neanderthals and modern humans. Subsequent study of the nuclear genome from this specimen suggests that Denisovans shared a common origin with Neanderthals, that they ranged from Siberia to South-East Asia, and that they lived among and interbred with the ancestors of some modern humans, with about 3% to 5% of the DNA of Melanesians and Aboriginal Australians deriving from Denisovans. 

Yet another human species

DNA discovered in Spain suggests that Denisovans at some point resided in Western Europe, where Neanderthals were previously thought to be the only inhabitants. A comparison with the genome of a Neanderthal from the same cave revealed significant local interbreeding with local Neanderthal DNA representing 17% of the Denisovan genome, while evidence was also detected of interbreeding with an as yet unidentified ancient human lineage.

This probably has nothing to do with the discovery of 'hobbits', another human species, on an island in Indonesia. Consequently, that means that there were at least 5 different humanoid species in existence at some time or another.

Similar analysis of a toe bone discovered in 2011 is underway, while analysis of DNA from two teeth found in layers different from the finger bone revealed an unexpected degree of mtDNA divergence among Denisovans. In 2013, mitochondrial DNA from a 400,000-year-old hominin femur bone from Spain, which had been seen as either Neanderthal or Homo heidelbergensis, was found to be closer to Denisovan mtDNA than to Neanderthal mtDNA.
