 In March 2010, Pääbo and his coworkers published a report about the DNA analysis of a finger bone found in the Denisova Cave in Siberia; the results suggest that the bone belonged to an extinct member of the genus "Homo" that had not yet been recognized, the Denisova hominin.In May 2010, Pääbo and his colleagues published a draft sequence of the Neanderthal genome in the journal "Science".He and his team also concluded that there was probably interbreeding between Neanderthals and Eurasian (but not Sub-Saharan African) humans.
