Ancient Denisovans and the human family tree
Natural History Museum, 12/01/2011
Last month scientists revealed remarkable evidence of a new group of ancient humans called Denisovans that interbred with our species and left behind a genetic trace in people living in south east Asia today. An international team, including scientists at the Max Planck Institute in Germany, carried out a genetic study of a finger bone and a large molar tooth uncovered in Denisova Cave in the Altai Mountains, Siberia. They sequenced the genome and found that this ancient human shared 4-6% of its genetic material with some present-day Melanesians. In March, the team obtained a complete mitrochondrial DNA (mtDNA) sequence for the same finger bone, dated to about 40,000 years ago, showing that it was from neither a modern human nor Neanderthal.
