You might think the obvious answer is “reproduction” but there are plenty of organisms on Earth that don’t require sex to reproduce. And the more that scientists examined sex, they more they realized that it’s an expensive and inefficient way to get your genes to the next generation. The true purpose of sex is actually one of the longest-standing mysteries in evolutionary biology. But scientists are closer than ever to finding the answer. Here’s what we know about the evolutionary enigma of sex.

SUBSCRIBE! ►► http://bit.ly/iotbs_sub ↓↓↓ More info and sources below ↓↓↓ Beavers have done more to shape North American landscapes than any animal beside humans. We don’t notice them much today because there aren’t many left, but before colonization, North America was home to hundreds of millions of these furry engineers. This week, we show you why Earth’s second largest rodent is more amazing than you ever knew, and why they’re the smartest thing in fur pants.

Why Are We The Only Humans Surviving?

Watch it all: http://bit.ly/OKTBSHuman ↓↓↓More info and sources below ↓↓↓ In part 2 of our special series on human ancestry, we ask why we are the only surviving branch on the human evolutionary tree. Just 50,000-100,000 years ago, Earth was home to three or four separate human species, including our most famous cousins: the Neanderthals. New research has shown that Neanderthals were not the brutish, unintelligent cavemen that cartoons make them out to be. They were creative, smart, social, and perhaps even had complex language. So why did they go extinct as soon as Homo sapiens moved into their territory? Does any trace of them live on today? Why don’t we have Neanderthal neighbors? ----------- REFERENCES: Papagianni, Dimitra, and Michael A. Morse. The Neanderthals Rediscovered: How Modern Science Is Rewriting Their Story.
