The disappearance of the elephant caused the rise of modern man 400,000 years ago

• http://phys.org, by Tel Aviv University
When Tel Aviv University researchers Dr. Ran Barkai, Miki Ben-Dor, and Prof. Avi Gopher of TAU's Department of Archaeology and Ancient Near Eastern Studies examined the published data describing animal bones associated with Homo erectus at the Acheulian site of Gesher Benot Ya'aqov in Israel, they found that elephant bones made up only two to three percent the total. But these low numbers are misleading, they say. While the six-ton animal may have only been represented by a tiny percentage of bones at the site, it actually provided as much as 60 percent of animal-sourced calories.

The elephant, a huge package of food that is easy to hunt, disappeared from the 400,000 years ago — an event that must have imposed considerable nutritional stress on Homo erectus. Working with Prof. Israel Hershkovitz of TAU's Sackler Faculty of Medicine, the researchers connected this evidence about with other cultural and anatomical clues and concluded that the new hominids recently discovered at Qesem Cave in Israel — who had to be more agile and knowledgeable to satisfy their dietary needs with smaller and faster prey — took over the Middle Eastern landscape and eventually replaced Homo erectus.
