Megafauna Extinctions and the Human Insanity Gene

Megafauna are big animals. Elephants and rhinoceros are megafauna, as are giraffes, whales, cows, deer, tigers, and even humans. The mass extinction of megafauna took place in bursts and started forty thousand years ago in Australia. The second burst was about fifteen thousand years ago in North and South America.
