A composite view of the Earth constructed by NASA from multiple satellite images Editor at Large Human evolution is a story writ slow. It’s been about 3.8 billion years since life on Earth emerged and ...

A digital reconstruction of a million-year-old skull suggests humans may have diverged from our ancient ancestors 400,000 years earlier than thought and in Asia, not Africa, a study found. The ...

Humans were living in rainforests roughly 150,000 years ago, some 80,000 years earlier than was previously thought—and may have been an important center for early human evolution. This is the ...

Human evolution is often told as a tidy story of adaptation, yet some of our most familiar body parts still defy straightforward explanation. From the jut of the human chin to the curve of the outer ...

The human body is a machine whose many parts – from the microscopic details of our cells to our limbs, eyes, liver and brain – have been assembled in fits and starts over the four billion years of our ...

For decades, scientists assumed that life on Earth emerged through a chain of highly improbable flukes. But a new theory suggests it may have instead arrived just in time. When you purchase through ...

A new Yale study provides a fuller picture of the genetic changes that shaped the evolution of the human brain, and how the process differed from the evolution of chimpanzees. For the study, published ...

In 1990, an ancient human skull was unearthed in China’s Hubei Province that was so badly deformed during fossilization that it was hard to gauge its significance. A new analysis now indicates that ...

"Human children grow at a uniquely slow pace by comparison with other mammals. When and where did this schedule evolve? Have technological advances, farming and cities had any effect upon it?
