Apparently our ancestors had more to worry about than bears, snakes and sabre tooths:

…small human ancestors known as hominids had to survive being hunted not only by large predators on the ground but by fearsome raptors that swooped from the sky, said Lee Berger, a senior paleoanthropologist at Johannesburg’s University of the Witwatersrand.

Apparently the Taung Baby was snatched and killed by an eagle.

I hate when that happens.
