New research suggests that the disappearance of elephants as a food source drove human evolution in the Middle East.

The elephant, a huge package of food that is easy to hunt, disappeared from the Middle East 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 diet 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.

The findings, which have been reported in the journal PLoS One, suggest that the disappearance of elephants 400,000 years ago was the reason that modern humans first appeared in the Middle East. In Africa, elephants disappeared from archaeological sites and Homo sapiens emerged much later — only 200,000 years ago.
