Image: East Africa's Homo erectus surrounded by contemporary fauna
Nearly 2 million years ago, Homo erectus first appeared typical of humans, such as a large brain
Generations of paleoanthropologists have traveled to famous well-preserved sites like Olduvai Canyon to find and discover, said W.
Barr and his colleagues compiled published data from nine major study areas in eastern Africa, including 59 site levels dating back between 2.
The researchers found that the relative numbers of carnivores did not consistently increase after the emergence of Homo erectus when changes in sampling effort over time were accounted for
"I've been excavating and studying cut-marked fossils for over 20 years, and what we find still blows my mind," said Brianna, a research scientist in the Smithsonian's National Museum of Natural History's Human Origins Program and co-author of the study.
In the future, the researchers stress the need for another explanation for why certain anatomical and behavioral features associated with modern humans emerge
"I think this study and its findings will be of interest not only to the paleoanthropological community, but to all those who are currently making dieting decisions based on this meat-eating claim," Barr said
