My professor once told us that we were thinking of Australopithecines, a recent hominid, all wrong.

While we thought of early human ancestors as less intelligent versions of ourselves, the correct analogy was to a modern Velociraptor: fast to the point of running animals to death, fiercely intelligent, and with unparalleled group coordination.

Arguably the last of the giant dinosaurs was the Moa, a bird with claws that could eviscerate a human with a single swipe, and our species wiped them out as a prey animal.

We are a terrifyingly effective species.
