In 1997, the very first Neandertal DNA sequence—just a small part of the mitochondrial genome—was determined from an individual discovered in the Neander Valley, Germany, in 1856. Since then, improvements in molecular techniques have enabled scientists at the Max Planck Institute for Evolutionary Anthropology to determine high quality sequences of the autosomal genomes of several Neandertals, and led to the discovery of an entirely new group of extinct humans, the Denisovans, who were relatives of the Neandertals in Asia.
