socrates states:
"The mystery is why almost all of the top predators stopped hunting on two legs and started hunting on four."

Why is that a mystery? The top predator on the planet has hunted on two legs for hundreds of thousands if not millions of years.

And would have killed any other predator that dared to challenge it position at the top of the food chain.

Don't believe me? Ask a Neandertal.
