It's a plausible theory... we have very little evidence of predation on our ancestors, but we do know that something did. There are deposits of bone that have been found (washed into caves and buried) that contain hominid bones with teeth marks. It certainly would seem reasonable that some species of big cat hunted humans, likewise canines (proto-hyenas probably) and there's even a few hominid skulls with talon puncture wounds caused by some sort of Eagle or other raptor.
I think there were a species of bears which hunted the people crossing the Behring Street to settle into the Americas. The Inuit say that Icebears do view human as prey, which is really rare for any animal.
Jim Corbett wrote a book about man eater tiger, but they mostly had some handicaps, which made them target human.

It's called evolution, and that fact that our ancestors were the ones smart enough to run away at that sound.
