'Lucy' lived among close cousins: Discovery of foot fossil confirms two human ancestor species co-existed
(Physorg.com)


(PhysOrg.com) -- A team of scientists has announced the discovery of a 3.4 million-year-old partial foot from the Woranso-Mille area of the Afar region of Ethiopia. The fossil foot did not belong to a member of "Lucy's" species, Australopithecus afarensis, the famous early human ancestor. Research on this new specimen indicates that more than one species of early human ancestor existed between 3 and 4 million years ago with different methods of locomotion. The analysis will be published in the March 29, 2012 issue of the journal Nature.

"The Burtele partial foot clearly shows that at 3.4 million years ago, Lucy's species, which walked upright on two legs, was not the only hominin species living in this region of Ethiopia," said lead author and project leader Dr. Yohannes Haile-Selassie, curator of physical anthropology at The Cleveland Museum of Natural History. "Her species co-existed with close relatives who were more adept at climbing trees, like 'Ardi's' species, Ardipithecus ramidus, which lived 4.4 million years ago."


There's been more and more evidence coming to light that the diversity of ancient hominds was much greater than previously thought and that many of these co-existed, much as the Neanderthal, Erectus, and modern Humans had. The 'Tumai' skull has really reset the evolutionary clock on human evolution to 6-7 millions years ago. The discovery of this foot fossil shows (once again) that human evolution wasn't exactly a straight line from A to B.

Fascinating. I was hoping, considering it's a physics site, we could get some constructive debate and hypothesizing in the comments section.. but alas, it devolved into a political debate between goddidit and nogoddidntdoit.

Yeah that comment section was hilarious - sad, but hilarious. I think if you feel that strongly about the evolution vs. God debate, you should save your opinions for a proper 'evolution vs. God' topic, and not troll every thread, topic, or article that talks about a scientific discovery.
