How did life on Earth begin? Theories abound, but one popular one posits that it started spontaneously from primordial ooze on our planet, while another holds that it literally came from outer space. Who's right?
Where did humans come from? How did they migrate throughout the globe? Thanks to a longstanding anthropological concept and an unexpected discovery, conventional wisdom on human migration may be irrevocably shattered.
When peering thousands of years into the future, there are certain things we can count on -- evolution, extinction, plate tectonics, climate change and, quite possibly, the eruption of a supervolcano. What else does the Earth's far future hold?

Maybe you've noticed that a lot of unrelated marine animals have a torpedo-like body -- a dolphin may not be related to a small fish, but the shape of both species gets each one through the water quickly. On the other hand, two similar species can evolve into entirely different species. So what's going on here: convergent or divergent evolution?

Our planet sits in the sun’s Goldilocks zone: the region that’s not too hot and not too cold. But it takes more than temperature to make a planet just right for supporting forms of life as diverse as the Earth’s.
我们的人类祖先发现大火一定是一个非常令人兴奋的那一天。多年来,我们已经以多种方式改变了,从增加大脑到埋葬死者。但是我们是如何从这里到达这里的?
Since Charles Darwin published the theory of evolution by means of natural selection, myths and misinterpretations have eroded public understanding of his ideas. Ready to take another look at one of the related questions that just won't die?

Many of us don't have a clue as to what our great-great grandmother's name was. (No offense, great-great grandmas everywhere.) So imagine extending that family tree a few million years beyond that and seeing what our ancestors were up to.
