In late 2010 it emerged from genomic studies of a finger bone
from Denisova Cave in eastern Siberia that a probably archaic
human group had shared genes with ancestors of some modern
humans who colonised West Pacific islands around 45 Ka ago, well
before the last glacial maximum. Melanesians, including tpeople
living in Papua-New Guinea have DNA that contains on average
around 6% contributed from fertile interbreeding with
Denisovans. This ancient groups are suggested by comparative
studies of their and Neanderthal mitochondrial DNA to have split
from them as lond as a million years ago. Now it seems possible
that much more complete fossils of Denisovans may have been
discovered in China (Curnoe, D. And 16 others 2012. Human
