New data on the Denisovans 

Our knowledge of the Denisovans is mainly derived from genetic analysis of finger phalanx. A very recent publication on PNAS reported nuclear and mtDNA sequence data from two additional molars specimens (Denisova 4 and Denisova 8) assigned to the Denisovans. The two molar specimens are reported to be older than 50,000 years based on radiocarbon dating and are morphologically distinct from Neanderthals and modern humans. The study confirmed the low genetic diversity of Denisovans proposed in earlier studies, although higher compared to Neanderthals,  and indicated a longer settlement, and possibly a wider geographic coverage of the Denisovans in the region inferred from the low substitution in the Denisova 8.
