How old is Y-chromosome Adam?
Dienekes has a thoughtful post in his December-30-2010 blog about
finding the age of Y-Chromosome Adam with a little help from Tim
Dienekes writes in part:
The presumed shallow time depth of the human Y-chromosome phylogeny is
one of the main arguments of the recent Out-of-Africa theory. One of
the major things I found while working on my Y-STR series is that
point estimates from Y-STR variation are associated with huge
confidence intervals, because of uncertainty about factors such as
generation length, population history, mutation rates, even if the
mutation model behaves "perfectly" in symmetrical stepwise fashion.

When I told my doctor about my memory loss, he made me pay in advance.
