Well, has he considered just asking Joe Paterno? *rimshot*
I imagine most animals did not have a fear of humans when the early Indians arrived (slow moving small animal without the four legs of all predators.)
I'm sure as climate change made the great herds of no-extinct animals weaker, that made them easy prey for 10 foot spears with massive clovis spearpoints.
I wonder if 10 foot high ground sloths were tasty?
