Wildlife is becoming "globalized," biologists warn, as the spread of animals and plants makes species more homogenous at the expense of regionally unique varieties.

Europeans owe their ancestry mainly to Stone Age hunters, not to later incomers who brought farming to Europe from the Middle East, new research suggests.

As populations' distance from Africa increases, genetic diversity decreases, according to a global DNA study. Researchers say the finding suggests early humans settled the planet in small steps.

Researchers have discovered fossilized remains of two previously unknown, monkeylike species that lived 37 million years ago.

The reported discovery of remains of nine more "hobbits" boosts the case that they represent a separate human species.

Among primates, modern humans take a long time to reach adulthood, and so did Neandertals, according to a new tooth study.

Ancient hunters, not climate change, may have spurred the extinction of giant sloths, saber-toothed cats, and other Ice Age mammals, a new study says.

Using new, microscopic technology to analyze dental wear-patterns, researchers have reconstructed the diets of two species of early humans.

Despite invasions by Romans, Vikings, and others, the genetic makeup of most white Britons has hardly changed since the Ice Age, a new book claims.

Researchers say natural selection may be behind the talented minds of Albert Einstein, Leonard Bernstein, and other people of European Jewish descent.

The arrival of humans in Australia 60,000 years ago caused the extinction of roughly 60 species of the continent's animals, scientists have found.

Archaeologists have found the world's earliest known glassmaking facility, revealing the crucial role of glass in ancient trade and politics.

Bones found more than a century ago in what is now the Czech Republic represent the earliest human settlement in Europe, new research confirms.

Two new genetic studies suggest modern humans left Africa between 60,000 to 75,000 years ago, crossing the Red Sea, then following the Indian Ocean coastline.

A new study shows how genes can help reveal how societal rules affect mobility.
