Experiment stresses consequences of placing newly discovered fossils on human family tree Someday a future intelligent organism could sweep away a million years of dust and find the bones of a Homo sapiens and wonder what he was. Further research would show Homo sapiens walked upright, lived in communities and buried their dead. But this future intelligent organism might be faced with an old puzzle--determining where Homo sapiens came from. "If their cognitive world induced them to ask the...

"Too simple" and "not so fast" suggest biological anthropologists from the George Washington University and New York University about the origins of human ancestry. In the upcoming issue of the journal Nature, the anthropologists question the claims that several prominent fossil discoveries made in the last decade are our human ancestors. Instead, the authors offer a more nuanced explanation of the fossils' place in the Tree of Life. They conclude that instead of being our ancestors the...

Paleontologists have found two new sabertooth species that use to roam in an ancient lakeside habitat in Africa, along with humankind's oldest known ancestor. A team unearthed the remains of a seven million-year-old human-like creature known as "Toumai" at the central African site. Its discoverers say that Toumai is the oldest hominid species known to exist. The Toumai's skull was found in the Djurab desert by a team led by Michael Brunet of the University of Poitiers, France....

Evolutionary divergence of humans from chimpanzees likely occurred some 8 million years ago rather than the 5 million year estimate widely accepted by scientists, a new statistical model suggests. The revised estimate of when the human species parted ways from its closest primate relatives should enable scientists to better interpret the history of human evolution, said Robert D. Martin, curator of biological anthropology at the Field Museum, and a co-author of the new study appearing in the...

LONDON (Reuters) - Humans' evolutionary split from their closest relatives, chimpanzees, may have been more complicated, taken longer and probably occurred more recently than previously thought, scientists said on Wednesday. After comparing the genomes, or genetic codes, of the two species they suggest the initial split took place no more than 6.3 million years ago and probably less than 5.4 million years ago. The process of separation may have taken about 4 million years and there...

AP -- New fossil finds and a computer skull reconstruction bolster the case that an ancient creature that grabbed headlines in 2002 really is the earliest known ancestor of modern humans, researchers say. In that year, scientists announced finding jaw fragments, some isolated teeth and a skull of a creature nicknamed "Toumai" in Chad. At some 6 million to 7 million years old, the fossils came from around the time of a major split in the evolutionary tree, with one branch leading eventually to...

PARIS (AFP) -- Palaeontologists say they have found a fossil haul from at least nine hominids who lived in eastern Africa more than four million years ago in the early chapters of human history. The discovery was made at As Duma in Ethiopia's Afar region, near the border with Djibouti, they report in Thursday's issue of Nature, the weekly British scientific journal. The find -- mainly teeth, pieces of jaw, hand and feet --- are dated as between 4.32-4.51 million years old and belonging to...
