    Full Title: Army general fired over charges of alcohol and sexual misconduct as military cleans out corruption in its African Command An Army major general with the U.S. Africa Command has been relieved of his post in connection with alcohol and sexual misconduct charges, defense officials said. Officials said Maj. Gen. Ralph Baker, commander of the Combined Joint Task Force-Horn of Africa, was fired from his command last Thursday, and he was fined a portion of his pay by Gen. Carter Ham, head of U.S. Africa Command, after an administrative hearing and review. The officials said Thursday that Ham lost...

    The discovery of the structure of DNA and the subsequent developments in genetics and genomics have had a great impact on all of the biological sciences, including human evolution. Our ideas about human evolution 60 years ago came primarily from the fossil and archaeological records. These fields revealed that the last two million years were a dynamic period of our evolutionary history. The human lineage two million years ago was a population with ape-sized brains limited to sub-Saharan Africa. The human lineage expanded into Eurasia around 1.85 million years ago, and our brain size increased throughout the Pleistocene. Anatomically modern...

    We present an Aboriginal Australian genomic sequence obtained from a 100-year-old lock of hair donated by an Aboriginal man from southern Western Australia in the early 20th century. We detect no evidence of European admixture and estimate contamination levels to be below 0.5%. We show that Aboriginal Australians are descendants of an early human dispersal into eastern Asia, possibly 62,000 to 75,000 years ago. This dispersal is separate from the one that gave rise to modern Asians 25,000 to 38,000 years ago. We also find evidence of gene flow between populations of the two dispersal waves prior to the divergence...
  • Out of (southern) Africa: Modern man 'evolved from desert bushmen'

    The first modern people evolved in southern Africa more than 60,000 years ago - and not in the east of the continent as most scientists believe, a study concludes. After analysing DNA samples from 27 populations in modern-day Africa, researchers say the most likely location for the 'cradle of humanity' is the Kalahari desert region of South Africa, Namibia and Botswana. The modern-day click-speaking bushman from the desert show the greatest genetic diversity of any Africans - suggesting that their home was the birthplace of the first true Homo sapiens.

    Chinese challenge to 'out of Africa' theory 00:01 03 November 2009 by Phil McKenna The discovery of an early human fossil in southern China may challenge the commonly held idea that modern humans originated out of Africa. Jin Changzhu and colleagues of the Institute of Vertebrate Palaeontology and Palaeoanthropology in Beijing, announced to Chinese media last week that they have uncovered a 110,000-year-old putative Homo sapiens jawbone from a cave in southern China's Guangxi province.
  • Ancient skull dug up in Henan may bury 'Out of Africa' theory

    Mainland archaeologists have discovered a fractured but almost complete skull in Xuchang , Henan province , that they believe is from an anatomically modern Homo sapiens nearly 100,000 years old. If the estimate is correct and if the skull, broken into 16 pieces seemingly by a powerful strike, demonstrates a feature of the East Asian population, then one of palaeoanthropology's paradigms - "Out of Africa" - may be shattered. Part of the Out of Africa theory holds that anatomically modern human beings first appeared in Africa. Then, about 100,000 years ago, they moved off the continent and took over the...
  • Study points to larger role of Asian ancestors in evolution (challenging "Out of Africa" theory)

    AFP (Yahoo!) ^ | Tue Aug 7, 8:10 AM
    CHICAGO (AFP) - A new analysis of the dental fossils of human ancestors suggests that Asian populations played a larger role than Africans in colonizing Europe millions of years ago, said a study released Monday. The findings challenge the prevailing "Out of Africa" theory, which holds that anatomically modern man first arose from one point in Africa and fanned out to conquer the globe, and bolsters the notion that Homo sapiens evolved from different populations in different parts of the globe. The "Out of Africa" scenario has been underpinned since 1987 by genetic studies based mainly on the rate of...

    LONDON (Reuters) - An analysis of thousands of skulls shows modern humans originated from a single point in Africa and finally lays to rest the idea of multiple origins, British scientists said on Wednesday. Most researchers agree that mankind spread out of Africa starting about 50,000 years ago, quickly establishing Stone Age cultures throughout Europe, Asia and Australia. But a minority have argued, using skull data, that divergent populations evolved independently in different areas. The genetic evidence has always strongly supported the single origin theory, and now results from a study of more than 6,000 skulls held around the world...

    Aborigines came out of Africa, study shows By Roger Highfield, Science Editor Last Updated: 2:24am BST 08/05/2007 Australia's Aborigines were formed from a single group of migrants who left Africa about 55,000 years ago, DNA evidence suggests. Once there the settlers evolved in relative isolation, developing genetic characteristics not found anywhere else and leading to unusual fossil finds that threatened the "out of Africa" hypothesis of human origins. DNA tests show that Aborigines did not develop separately but were part of the migration from Africa 55,000 years ago However, research published today confirms that all modern humans stem from a...

    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...

    Ancient drought 'changed history' By Roland Pease BBC science unit, San Francisco The sediments are an archive of past climate conditions Scientists have identified a major climate crisis that struck Africa about 70,000 years ago and which may have changed the course of human history.The evidence comes from sediments drilled up from the beds of Lake Malawi and Tanganyika in East Africa, and from Lake Bosumtwi in Ghana. It shows equatorial Africa experienced a prolonged period of drought. It is possible, scientists say, this was the reason some of the first humans left Africa to populate the globe. Certainly,...

    May 13, 2005 DNA Study Yields Clues on Early Humans' First Migration By NICHOLAS WADE By studying the DNA of an ancient people in Malaysia, a team of geneticists says it has illuminated many aspects of how modern humans migrated from Africa. The geneticists say there was only one migration of modern humans out of Africa; that it took a southern route to India, Southeast Asia and Australia; and that it consisted of a single band of hunter-gatherers, probably just a few hundred people strong. Because these events occurred in the last Ice Age, when Europe was at first too...

    New Evidence Challenges "Out-of-Africa" Hypothesis of Modern Human origins New evidence challenges "Out-of-Africa" hypothesis of modern human origins WUHAN, April 27 (Xinhua) -- Chinese archaeologists said newly found evidence proves that a valley of Qingjiang River, a tributary on the middle reaches of the Yangtze River, might be one of the regions where Homo sapiens, or modern man, originated. The finding challenges the "Out-of-Africa" hypothesis of modern human origins, according to which about 100,000 years ago modern humans originated in Africa, migrated to other continents, and replaced populations of archaic humans across the globe. The finding comes from a large-scale...

    At the start of his 5-day trip to Africa, President Bush denounced slavery as "one of the greatest crimes of history." Equally repulsed by slavery, Washington Post reporter Keith Richburg nonetheless wonders, after spending three years in war-torn and disease-ravaged Africa, what his fate would have been had his ancestors not been sold as slaves roughly 400 years ago.In the week to come, Bush will encourage emergent democracies in Africa, and condemn militant rulers in the region. He appears close to sending 2,000 U.S. troops to Liberia to join an international peacekeeping force. In addition, Bush aims to alleviate the...

    The eyes of the world are temporarily on Africa because George W. Bush is making his first trip (five days) there. The issues of HIV/AIDS, despotism, inhumanity and corruption on the continent are in the spotlight. For me, an African-American, one of the most important recent trends related to Africa is the courage of a growing number of prominent blacks in the United States to publicly criticize African heads of state. I am especially pleased that black organizations, such as the TransAfrica Forum and Howard University's Africa Action, have sent formal complaints to several African leaders, including Presidents Robert Mugabe...

    To the Editor: "The Beginning of Modern Humans" (editorial, June 15) states that a newly discovered Ethiopian skull more than 150,000 years old is "recognizably modern to paleoanthropologists but not to most of the rest of us." It does not look recognizably modern to this paleoanthropologist, and it is a much less probable candidate for being the ancestor of the modern European human than the European Neanderthal is. I have superimposed the outlines of the crania being compared. Statistical analysis of a battery of measurements shows that the European Neanderthal is more closely related to modern Europeans than to anyone...
