Elephants and human evolution  DEC 13 2011

Elephants were the "perfect food package" for pre-human hominids (they were slow with a good fat-to-protein ratio) and their extinction in the Middle East (and Africa) caused those hominids to evolve to be more like modern humans.

When elephants began to die out, Homo erectus "needed to hunt many smaller, more evasive animals. Energy requirements increased, but with plant and protein intake limited, the source had to come from fat. He had to become calculated about hunting," Ben-Dor says, noting that this change is evident in the physical appearance of modern humans, lighter than Homo erectus and with larger brains.
