The data was telling her that the roughly 90,000-year-old flake of bone she had tested was from a teenager that had a Neanderthal mom and Denisovan dad.
Quote:
After running tests on six samples in all, the results always came out the same: The bone had nearly equal amounts of DNA from a Neanderthal and a Denisovan.
Quote:
Further study showed that the Denisovans were a sister group of the Neanderthals, splitting from a common ancestor some 390,000 years ago. They likely lived until around 40,000 years ago, around the time when Neanderthals were also starting to fade away.
But many questions remain. What did they look like? How many where there? Did they only live around this single Siberian cave? The problem is that Denisovan remains are exceedingly scarce. Everything scientists know about them has been extracted from scanty tracesjust three teeth and a pinkyof four Denisovan individuals all found in the same cave.
