North America had megafauna for 55 million years. Do you really think it's coincidence that they all died out 10,000 years ago?

- stubish 3y agoThe same environmental changes that encouraged humans and other smaller predators to spread to the Americas may also have lowered the population of the megafauna. But yes, I tend to believe that the environmental change that killed of the megafauna was the arrival of predators smart enough to use pointy sticks and fire, which we call evolution.
