The bony facial protrusion might be an evolutionary byproduct that resulted from changes to other parts of the skull, according to a new study ...

A new study explains why humans have chins while other primates do not. Researchers found that the chin likely formed as a ...

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 ...

“The chin evolved largely by accident and not through direct selection, but as an evolutionary byproduct resulting from direct selection on other parts of the skull,” University of Buffalo biological ...

Pigeons keep droning on and on in the sky, from one spot to another they map out expanses with just flapping. But in Russia, ...

The finding, along with the discovery of a 500,000-year-old hammer made of bone, indicates that our human ancestors were making tools even earlier than archaeologists thought. By Franz Lidz Early ...

Where did our species first emerge? Fossils discovered in Morocco dating back more than 773,000 years bolster the theory that Homo sapiens originally appeared in Africa, scientists said in a study ...

Re-dating volcanic ash layers above fossils in Ethiopia shows that early Homo sapiens lived at least 230,000 years ago. The findings narrow the gap with Moroccan fossils and strengthen the case for an ...

Modern humans were not always the dominant species on Earth. For tens of thousands of years, Homo sapiens shared the planet with other human species that were stronger, faster, and better adapted to ...

Homo sapiens were thought to have appeared about 600,000 years ago, but two closely related million-year-old skulls suggest that our species might be even more ancient. When reconstructed, the more ...

In a rocky outcrop on Mount Carmel, in what is now Israel, a group of ancient humans buried their dead about 140,000 years ago. Scientists uncovered the site, called Skhul Cave, in 1928, and about ...
