An archaeologist friend of mine just sent me this:

Hints of an unidentified, extinct human species have been found in the DNA of modern Melanesians - those living in a region of the South Pacific, northeast of Australia.
According to new genetic modelling, the species is unlikely to be Neanderthal or Denisovan - two ancient species that are represented in the fossil record - but could represent a third, unknown human relative that has so far eluded archaeologists.
