Denisovans and others
Just over a year ago, I wrote a piece about the 2012 discovery of a group of early hominins, the Denisovans, from a cave in Siberia. All that was initially found was a finger bone, from which was extracted some DNA, which showed the owner as not belonging to the Neanderthals. This finger bone belonged to the first group of archaic humans to be revealed solely by their DNA and associated proteins, rather than the morphology of their fossilised bones.
