Mailbag: Chinese subspecies and Denisovans

Re: Denisova:

Thank you for the very rapid FAQ on this fascinating new article! As you say,
the findings should not be unexpected. Even the contribution from archaics to
present-day Melanesians was foretold by the New Mexico group. Maybe this will
put some sanity into those recurring "Modern humans are from China not Africa"
stories. Pleistocene Homo sapiens in Asia just gets no respect! This seems to
show a population of “Chinese Neanderthals” replacing H. erectus and later being
replaced by OOA, but neither is quite 100%.

Just thinking… If present-day populations, Neanderthals, and “Denisovans” make a
near-trichotomy of SUBSPECIES, perhaps Homo sapiens mapaensis Kurth 1965 or Homo
sapiens daliensis Wu Xinzhi 1981 will be found to have priority…

Yes, I suspect those names may be available, depending on the timing of these population divergences. The Chinese record has several shoes left to drop.

Neandertals

For years, I've worked on their bones. Now I'm working on their genes. Read more about the science studying these ancient people.

Denisova

From a finger bone of an ancient human came the record of a completely unexpected population. My lab is working on the science of the Denisova genome.

Acceleration

The advent of agriculture caused natural selection to speed up greatly in humans. We're uncovering some of the ways that populations have rapidly changed during the last 10,000 years.

Malapa

Just outside Johannesburg, the Malapa site is producing some of the most exciting finds in human evolution. This site is the headquarters of the Malapa Soft Tissue Project.
