Paleoanthropologists caught their first glimpse of the Denisovans in 2010, when Pääbo's group sequenced an mtDNA genome from a girl's pinky finger from Denisova Cave. Later, the nuclear genome showed the Denisovans were more closely related to Neandertals than to modern humans (Science, 28 January 2011, p. 392). Denisovan DNA shows up in some Southeast Asians, suggesting that ancient Denisovans mixed with our ancestors in Asia.
