"This is the first time the whole genome of an ancient human has been analyzed, and it joins the list of just eight whole genomes of living people that have been decoded so far."
So there are still plenty of complete genomes yet to be done as the technology becomes less expensive. More cases will result in more information about variations among human beings.
"Biologists used to think that DNA would be found only in the cells at the roots of the hair, not in the keratin of which the hair shaft is made. But it now seems that the cells become incorporated into the growing shaft and their DNA is sealed in by the keratin, protecting it from attack by bacteria and fungi."
That opens up the possibility of complete genome sequences of more ancient persons. Permafrost is great for preservation of human remains. There will never be this level of detail for many persons from tropical zones.
