Giant Hyenas versus stone-age Man
Okay, so its science day. But this was too good not to share, too. The story suggests that the domestication of dogs was a key to Man being able to colonize the northeast of Asia, and subsequently, the Americas. I always thought the Cenozoic was under-appreciated compared to the Mesozoic (Age of the Dinosaurs). I like the Hall of Extinct Mammals in the AMNH as much as the Dinosaur Halls.
