Bigger Kill Than Chill: The Uneven Roles of Humans and Climate on Late Quaternary Megafaunal Extinctions
As human populations spread out of Africa to other continents starting around 50,000-years ago, the greatest extinction event since the dinosaurs occurred. The “Great Debate” over the Pleistocene Extinctions (when 80% of America’s genera abruptly disappeared) is whether the extinctions were caused by humans, or by changing climate.
