They must have had some hair follicles. I did not think that you could get
DNA from just hair (chitin) and that hair was often contaminated by what
people put on it including animal fats. Am I wrong? Bryan

The 11 Feb 2010 issue of Nature contains a very interesting (and important)
article by Rasmussen et al, "Ancient human genome sequence of an extinct
Palaeo-Eskimo", pp. 757-762. The DNA from a tuft of hair found in permafrost
in Greenland, dated about 4000 bp, is extensively analyzed. They have
apparently been able to do a more complete sequencing job of the genome than
has been possible for the Neanderthals. They mention, for example, finding
4024 SNPs on the Y, of which they call 243 to be of "high confindence" and a
total of 353,151 for the what they call the Saqqaq genome. The haplogroup is
stated as Q1a*. They were also able to draw various conclusions about the
phenotype of the Saqqaq man. Interestingly, they don't seem to have had a
problem extracting DNA from hair samples. The supplementary information
(only obtainable on-line) is quite extensive, being 87 pages long.

Yup, the whole thing (or pretty much):

It's the cover article in the February 11 issue of Nature,
