The first analysis of any Neanderthal DNA was mitochondrial DNA (mtDNA), published in 1997. The sample was taken from the first Neanderthal fossil discovered, found in Feldhofer Cave in the Neander Valley in Germany. A small sample of bone was ground up to extract mtDNA, which was then replicated and analyzed.The discovery that such fossils can harbor bacterial communities different from those in the surrounding stone complicates the search for dinosaur DNA, proteins and other biomolecules.Welcome to our new, FREE beta platform where you can discover more about the haplogroup from your Y-DNA test.
