Doing archaelogy via DNA

The ABC has reported that Australian scientists have mapped the entire DNA sequence of a 4000 year old human remains.

"It gave some fascinating insights into its biology, like he had certain genes that were more adaptive to living in the cold," Dr Bunce said.
"We can tell his blood type. We can tell he had a dry type of ear wax, and you can make hypotheses about his eye colour and hair colour.
"It's sort of a new way of doing archaeology, which is exciting."

This is pretty interesting science it makes me wonder what implications there will be for looking at the evolutionary process. Such as will it reveal the evolutionary 'missing link. I wonder if Dawkins will have any thoughts on this...'
