He lived hundreds of thousands of years ago, eking out an existence in what is today central China. Sporting a squat neck and a big brain, he likely wielded tools made of stone and hunted or scavenged ...

Fossils unearthed in Ethiopia are reshaping our view of human evolution. Instead of a straight march from ape-like ancestors to modern humans, researchers now see a tangled, branching tree with ...

Four lifelike reconstructions of prehistoric humans have been unveiled — including a model of a species often dubbed "the hobbit," which, as an adult, was about the same height as a modern 4-year-old.

A large-scale climate simulation combined with fossil evidence shows how shifts in temperature and rainfall guided human migration and evolution. Changes driven by Earth’s orbital cycles altered ...

Throughout most of human history, evolution progressed slowly. Small genetic changes took thousands of years to permeate populations. Natural selection was intentional, reactive, and gradual. However, ...

Researchers found that ancient hominids—including early humans—were exposed to lead throughout childhood, leaving chemical traces in fossil teeth. Experiments suggest this exposure may have driven ...

We are indeed still evolving, though it can be hard to tell because it happens over generations and often involves things you can't see, such as what foods different people are able to digest. When ...
