Biologists have debated the reason why Homo sapiens evolved a prominent lower jaw, but this unique feature may actually be a by-product of other traits shaped by natural selection ...

Life on Earth began in a way that still boggles the mind. Around 4.5 billion years ago, a chemical process called abiogenesis ...

One of the defining features of human evolution is the steady expansion of our brains. New findings suggest this growth may be partly linked to higher levels of estrogen before birth. Surprisingly, a ...

Human newborns arrive remarkably underdeveloped. The reason lies in a deep evolutionary trade-off between big brains, bipedalism and the limits of motherhood.

Like other living creatures, humans have been shaped by evolution. Over time, we have developed – and continue to develop – traits that help us survive.

The chin is one of our most familiar features, yet scientists still debate why we evolved it. Here’s a breakdown of what we know about it so far.

In 1758, Swedish biologist Carl Linnaeus gave humans a scientific name: Homo sapiens, which means "wise human" in Latin. Although Linnaeus grouped humans with other apes, it was English biologist ...

Add Yahoo as a preferred source to see more of our stories on Google. A reconstruction of the crushed skull labelled Yunxian 2, which has features that are closer to species thought to have existed ...

Humans' exposure to high temperature burn injuries may have played an important role in our evolutionary development, shaping ...

Learn how repeated burn injuries may have acted as a form of natural selection, influencing human genes linked to healing and immune response.
