Age of Elephants

Today there are only three species of elephant, but 16 million years ago there were dozens. The evidence comes from Buluk, a site in northern Kenya, where scientists have found an astonishing range of elephant fossils. It was a kind of elephant Jurassic Park, a place one scientist calls the center of the empire of the age of elephants. What happened to all those species? Over many millions of years, due to climate change and predation pressure from humans, elephants waned until today there are only three species left.
