Calling us different species is laughable. We’re the genetic equivalent of putting 2 rabbits in a box and opening it up to find 300.

Didn't the human population drop to something like 2000 individuals at some point in history? Would be like dropping 2 rabbits in a box and opening it up to see 4 million.
