Genomic sequencing reveals new evidence of interbreeding among different groups of our ancient relatives. A scientist calls the find "almost too lucky to be true."
Some genetic tests for a common cause of sudden heart failure can be wrong, researchers say, because the underlying science didn't take into account racial diversity.
Some of the genetic variations in human DNA that have been linked to quick clotting or depression or diabetes lie within or near the genetic stretches we picked up from Neanderthals, a study finds.
Scientists assume a wave of people from what's now Siberia crossed into North America via Alaska, maybe 23,000 years ago. Genetics support that, but may also suggest another wave from Australasia.
