It seems some of our earliest ancestors possessed a rather unsteady stride due to subtle anatomical differences. Schwartz and Gebo's findings will be published in the April 2006 edition of the American Journal of Physical Anthropology, but the...
  • New analysis shows three human migrations out of Africa, Replacement theory 'demolished'

    Washington University in St. Louis ^ | 02 February 2006 | Tony Fitzpatrick
    A new, more robust analysis of recently derived human gene trees by Alan R. Templeton, Ph.D, of Washington University in St Louis, shows three distinct major waves of human migration out of Africa instead of just two, and statistically refutes — strongly — the 'Out of Africa' replacement theory. That theory holds that populations of Homo sapiens left Africa 100,000 years ago and wiped out existing populations of humans. Templeton has shown that the African populations interbred with the Eurasian populations — thus, making love, not war. "The 'Out of Africa' replacement theory has always been a big controversy," Templeton...

    In their study of the evolutionary ladder, scientists have found that modern humans rubbed elbows with some colorful cousins. But few have been as puzzling as a purported cousin unearthed on the Indonesian island of Flores. The partial skeleton, first reported last October, was stunning. Estimated to stand just over three feet tall, it offered the tantalizing possibility that a new species of mini-human lived 18,000 years ago. But some researchers dismissed the find as a pygmy or the result of a physical defect. Now the research team that gave the world the hobbit-like Homo floresiensis has found what it...

    A gene that is responsible for the pale skin of Europeans and the dark skin of Africans has been discovered by scientists at Pennsylvania State University. The gene comes in two versions, one of which is found in 99 percent of Europeans and the other in 93 to 100 percent of Africans, the researchers report in today's issue of Science. The gene is unusual because with most human genes, different versions are generally shared, though one version may be more common in one race than another. One exception is the Duffy null allele, a version of a gene that prevents...

    Scientists said yesterday that they have discovered a tiny genetic mutation that largely explains the first appearance of white skin in humans tens of thousands of years ago, a finding that helps solve one of biology's most enduring mysteries and illuminates one of humanity's greatest sources of strife. The work suggests that the skin-whitening mutation occurred by chance in a single individual after the first human exodus from Africa, when all people were brown-skinned. That person's offspring apparently thrived as humans moved northward into what is now Europe, helping to give rise to the lightest of the world's races. Leaders...

    Palaeontologists excavating a dump outside Barcelona have found a skull dating back 14m years that could belong to a common ancestor of apes and humans. The nearly intact skull, which has a flat face, jaw and teeth, may belong to a previously unknown species of great ape, said Salvador Moya, the chief palaeontologist on the dig. "We could find a cradle of humanity in the Mediterranean," he said. A routine land survey for a planned expansion of the Can Mata dump in Els Hostalets de Pierola turned up the first surprise in 2002: a primate's tooth. Since then, scientists from...

    Scientists digging in a remote Indonesian cave have uncovered a jaw bone that they say adds more evidence that a tiny prehistoric Hobbit-like species once existed. The jaw is from the ninth individual believed to have lived as recently as 12,000 years ago. The bones are in a wet cave on the island of Flores in the eastern limb of the Indonesian archipelago, near Australia. The research team which reported the original sensational finding nearly a year ago strongly believes that the skeletons belong to a separate species of early human that shared Earth with modern humans far more recently...

    IT IS possibly the longest-running murder mystery of them all. What, or even who, killed humankind's nearest relatives, the Neanderthals who once roamed Europe before dying out almost 30,000 years ago? Suspects have ranged from the climate to humans themselves, and the mystery has deeply divided experts. Now 30 scientists have come together to publish the most definitive answer yet to this enigma. They say Neanderthals simply did not have the technological know-how to survive the increasingly harsh winters. And intriguingly, rather than being Neanderthal killers, the original human settlers of Europe almost suffered the same fate. Ice cores recovered...

  • Mitochondrial DNA Mutation Rates

    Mitochondrial DNA Mutation Rates David A. Plaisted Recently an attempt was made to estimate the age of the human race using mitochondrial DNA. This material is inherited always from mother to children only. By measuring the difference in mitochondrial DNA among many individuals, the age of the common maternal ancestor of humanity was estimated at about 200,000 years. A problem is that rates of mutation are not known by direct measurement, and are often computed based on assumed evolutionary time scales. Thus all of these age estimates could be greatly in error. In fact, many different rates of mutation are...

Previously it was thought that Britains repopulation was a slow process led by a few pioneering explorers. Researchers now know that humans responded rapidly to climate change and moved into Britain en masse as soon as the ice receded. Up to 20,000 years ago a huge ice sheet extended as far south as Norfolk. Then temperatures rose rapidly, producing warming weather than we have now. Once...

    THE discovery of human footprints, preserved by volcanic ash, have put back the likely date that the American continent was colonised by Man by almost 30,000 years, British scientists say. The prints, found by the scientists at the edge of a lake in Mexico, are thought to be about 40,000 years old. Their discovery upsets the widely accepted theory that Man first reached America across a land bridge, now covered by the Bering Sea, 11,500 years ago. Casts of the footprints reveal that a community of Homo sapiens lived in the Valsequillo Basin, near Puebla in central Mexico. Their feet...

Radiocarbon dated to 40,700 14C years before present, this specimen is one of the most recent Middle Paleolithic Neandertals. The diaphysis derives from an archeological level indicating alternating human and carnivore (mostly hyena) occupation of the cave, reinforcing the close proximity and probable competition of Middle Paleolithic humans with large carnivores for resources and space. Morphological aspects of the diaphysis and ancient DNA extracted from it indicate that it is aligned with the Neandertals and is distinct from early modern humans.

Though the region, a stretch of DNA on the 17th chromosome, occurs in people of all countries, it is much more common in Europeans, as if its effect is set off by something in the European environment. A further unusual property is that the region has a much more ancient lineage than most human genes and the researchers suggest, as one possible explanation, that it could have been inserted into the human genome through interbreeding with one...

However, there is controversy over theories that Neanderthals made a contribution to the modern human gene pool. A skeleton uncovered in Portugal appeared to show both Neanderthal and human features. DNA taken The latest research, from the University of Ferrara in Italy, compared genetic material from Neaderthals, Cro-Magnon humans and modern Europeans. The DNA from the Neanderthals and Cro-Magnons was taken from their bones. The DNA came from cell structures called mitochondriae rather than the nucleus. They found that while, unsurprisingly,...

    The discovery of a new species of human astounded the world. But is it what it seems? John Vidal went to remotest Flores to find out If you want to understand human evolution, it may be worth starting with Johannes Daak from the remote village of Akel in the heavily forested centre of the Indonesian island of Flores. Johannes, from the Manggarai ethnic group, reckons he is 100 years old and says he owes his longevity and enduring strength to having only ever known one woman. He says he owes his stature to his ancestors. Johannes is no more than...

    Did Humans and Neandertals Battle for Control of the Middle East? By Ben Harder for National Geographic News March 8, 2002 Thousands of years before Christians, Muslims, and Jews became locked in dispute over the Middle East, humans wrested control of the region from its true original inhabitants, the Neandertals, in what one scientist compares to a prolonged game of football. The Neandertals, stocky and intelligent humanoids, lived in Europe and Western Asia for thousands of years before the first humans settled in the area. Then true humans moved into the region from Africa. Face-to-Face Fight The new arrivals settled ...

    Excalibur, the rock that may mark a new dawn for man Paleontologists claim 350,000-year-old find in Spanish cave pushes back boundary of early human evolution Giles Tremlett in Madrid Thursday January 9, 2003 The Guardian They have called it Excalibur, though it was plucked from a pit of bones rather than the stone of Arthurian legend. To the ordinary eye it is a hand-sized, triangular chunk of ochre and purple rock, its surface slightly scratched. But to the palaeontologists who found this axe-head buried in a deep cavern on a Spanish hilltop, it is proof of a terrible and defining...

    Fossil hints at primate origins The bone is just over a centimetre long An ankle bone discovered in central Burma could be evidence of an ancient ancestor common to many of today's primates, including humans. The 45-million-year-old fossil has features that link it to all of the anthropoids, the grouping of human-like species such as apes and monkeys. If correct, this would tie their line of evolutionary descent to Asia and not Africa as some have suggested. The findings appear in the Proceedings of the National Academy of Sciences. The PNAS journal presents a paper on the discovery by Laurent...

    LONDON (Reuters) - Fossils discovered in Ethiopia's highlands are a missing piece in the puzzle of how African mammals evolved, a team of international scientists said on Wednesday. Little is known about what happened to mammals between 24 million to 32 million years ago, when Africa and Arabia were still joined together in a single continent. But the remains of ancestors of modern-day elephants and other animals, unearthed by the team of U.S. and Ethiopian scientists 27 million years on, provide some answers. "We show that some of these very primitive forms continue to live through the missing years, and...

    The theory that we are all descended from early humans who left Africa about 100,000 years ago has again been called into question. US researchers sifting through data from the human genome project say they have uncovered evidence in support of a rival theory. Most scientists agree with the idea that our ancestors first spread out of Africa about 1.8 million years ago, conquering other lands. What happened next is more controversial. The prevailing theory is that a second exodus from Africa replaced all of the local populations, such as Europe's Neanderthals. Some anthropologists, however, advocate the so-called multiregional theory,...

    NEW YORK (Reuters Health) - A gene found in redheads and fair-skinned people may also play a role in the body's natural pain suppression system. But the gene, Mc1r, appears to impact pain suppression only in women, according to the study, published Monday in the advance online publication of the Proceedings of the National Academy of Sciences (news - web sites). The researchers found that redheaded women were able to tolerate more pain than other people when given an analgesic drug called pentazocine. All redheaded men, as well as men and women who did not have red hair, had similar-and...

    Genes may be reason for Jews' low alcoholism rate Genes, and not religious conviction, explain why Jewish people typically have fewer drink problems than non-Jews. Researchers in the US say a genetic mutation carried by at least a fifth of Jews appears to protect against alcoholism. The same inherited trait is fairly common in Asian people, but is much rarer in white Europeans. The Daily Telegraph says the findings could help explain why Israel has one of the lowest levels of alcoholism in the developed world. The mutation, called ADH2*2, is involved in the way the body breaks down alcohol...

    Every species seems to come and go. Some last longer than others, but nothing lasts forever. Humans are a relatively recent phenomenon, jumping out of trees and striding across the land around 200 000 years ago. Will we persist for many millions of years to come, or are we headed for an evolutionary makeover, or even extinction? According to Reinhard Stindl, of the Institute of Medical Biology in Vienna, the answer to this question could lie at the tips of our chromosomes. In a controversial new theory he suggests that all eukaryotic species (everything except bacteria and algae) have an...

    <p>The expression "clothes make the man" may be more prescient than imagined. New theories about our evolutionary development are making the rounds in scientific journals that attempt to explain why modern humans shed the fur that characterized earlier hominids.</p> <p>Evidence is mounting that when our ancestors wandered out of the forests and onto the African savannas 1.7 million years ago, they weren't simply leaving leafy trees behind. Many millennia before the heartbreak of psoriasis, early humans had an affliction that surely would've led to an unbearably itchy existence, if not extinction, had we not shed our matted body hair over hundreds of generations.</p>

    Neanderthal DNA Sequencing ^ | FR Post 2-3-03 | Essays by James Q. Jacobs
    Neanderthal DNA Sequencing In July of 1997 the first ever sequencing of Neanderthal DNA was announced in the Jouranl Cell (Krings, et. al., 1997), a breakthrough in the study of modern human evolution. The DNA was extracted for the type specimen and the mitochondrial DNA sequence was determined. This sequence was compared to living human mtDNA sequences and found to be outside the range of variation in modern humans. Age estimation of the Neanderthal and human divergence is four times older than the age of the common mtDNA ancestor of all living humans. The authors suggest that the Neanderthals...

    Neanderthal 'face' found in Loire By Jonathan Amos BBC News Online science staff A bone splinter forms the eyes A flint object with a striking likeness to a human face may be one of the best examples of art by Neanderthal man ever found, the journal Antiquity reports. The "mask", which is dated to be about 35,000 years old, was recovered on the banks of the Loire at La Roche-Cotard. It is about 10 cm tall and wide and has a bone splinter rammed through a hole, making the rock look as if it has eyes. Commentators say the object...
