Neanderthals, the closest cousins of modern humans, lived in parts of Europe and Asia until their extinction some 30,000 years ago. Genetic studies are revealing ever more about the links between ...

For decades, the Y chromosome — one of the two human sex chromosomes — has been notoriously challenging for the genomics community to sequence due to the complexity of its structure. Now, this elusive ...

Scientists trace Leonardo da Vinci's DNA through his descendants and family tombs to reconstruct his genetic code.

We know that Neanderthals left their mark behind in the DNA of many modern humans, but that exchange worked both ways. The groups of Neanderthals our species met in Eurasia around 45,000 years ago ...

The Y chromosome is perhaps the most puzzling part of the human genome. Associated with male development, it is chock-full of repetitive and inverted stretches of DNA, a hurdle that makes it ...

The Seminole tribe of Florida consists of 2,300 individuals who reside on five federal-trust reservations in South Florida which include Hollywood, Big Cypress, and Brighton. Approximately 600 tribal ...

Debate has long surrounded when humans first traveled into Sahul, the ancient landmass that is now Australia, New Guinea and ...
