Bipedalism, or walking on two legs, is one of the key features that distinguishes humans from other apes. But when and why our ancestors transitioned from a life often spent in trees to a life spent ...

Two mysterious human relatives left their genetic footprints in the modern human genome alongside the DNA of Neanderthals and Denisovans, underscoring the fact that our ancestors interbred with many ...

Walking on two legs has long been considered a milestone in human evolution and one of our most defining characteristics. Until now, researchers assumed that the first humans originated in Africa and ...

Ancient encounters between humans and the mysterious Denisovans are still shaping people today. By analyzing genomes from populations across the Pacific, researchers uncovered evidence that the ...

Mosquitoes haven’t always had a taste for human blood — partly because the tiny yet dangerous insects have been around a lot longer than humans. Pinpointing when mosquitoes shifted their preference to ...

A new study suggests humans became overwhelmingly right-handed because of two major evolutionary shifts: walking on two legs and developing much larger brains. Researchers found that as human ...

Humans really do rule the world. We took over fast and far, more than any other wild vertebrates. We inhabit nearly every corner of the world, and can thrive in deserts, tropical rainforests and even ...

A new landmark study has uncovered evidence that challenges the long-held beliefs about human evolution.

Some researchers hold that evolution hasn’t much altered humans in the past 10,000 years. A new analysis of ancient DNA indicates that natural selection continued to shape hundreds of genes. By Carl ...
