Ancient human DNA found in Ice Age caves — even when bones were missing

Scientists found DNA from ancient humans in the soil of caves — even when there were no bones uncovered at the site. The research shows that, even when no fossils are around, sediments inside caves can tell us which early humans were present where and when. This information is key for understanding the evolution of our human ancestors.
The study, published today in Science, describes a highly sensitive technique for analyzing ancient DNA. The technique was used to study sediment from seven
