The biological makeup of humans in East Asia is shaping up to be a very complex story, with greater diversity and more distant contacts than previously known, according to a new study in Current Biology. It analyzes the genome of a man that died in the Tianyuan Cave near Beijing, China 40,000 years ago. His bones contained enough DNA molecules for a team led by Professor FU Qiaomei at the Molecular Paleontology Lab at the Chinese Academy of Sciences to use advanced ancient DNA sequencing techniques to retrieve DNA that spans the human genome.
