	From the linked article:  "Until now, when the hair root hadn't been 
available for analysis, scientists had thought analysing the hair shaft 
was of relatively little use as it contained so little DNA.

But isolated strands of hair are often the only clues to human 
habitation in ancient times.

Now Gilbert's team said it had developed a method to extract and 
sequence ancient DNA from hair shafts."
