Genetic material from old artifacts can link people to their ancestral communities and potentially help descendants find their roots.

Denisovans and Neanderthals likely overlapped at this Stone Age hot spot for thousands of years, and modern Homo sapiens may have dwelled there, too.  

The findings of a new study contradict previous results from some of the same scientists that suggested Neanderthal DNA was gradually removed from modern human genomes.

Genetic information from dozens of individuals living 700 to 10,000 years ago reveals connections between Clovis and Native Americans and South Americans.

Unlike other populations living at high altitude, Andeans didn’t rely on hypoxia-related genes.

European settlers likely wiped out these ancient dogs, but the animals seem to have left a lasting legacy in a transmissible canine cancer.

Researchers are resurrecting proteins from millions of years ago to understand evolution and lay the groundwork for bioengineering custom molecules.

Analyses of more than 300 ancient human genomes show that Hepatitis B virus has infected humans for at least 4,500 years and has much older origins than modern viral genomes would suggest.
