Hi Ricardo,

From what I have read on the distribution of the A allele, it is
"newer" than the O allele. "B" was next, leading to "AB" as the newest
and rarest. Some claim that these are evolutions in the human immune
capabilities that arose from plague and other viral survivals and that
it is a predominate IE or Indo European consistancy.
With this I would assume that since the amerindian populations of the
Americas are predominately O, the appearance of A would signal the
arrival of its migrations from Europe.
West African populations that were imported to the the Americas were
predominately O (have the data on this somewhere in my huge files). Many
of these groups became rare in Africa after their distributions to other
continents. The Duffy Null antigen was the flagging of this distribution.
Check out the link for the Blood Book as it addresses the histories and
distributions of blood types enough to see and understand this. Of
course, there are controversaries around this now, but this data is
mainly based on the anthropology of human migrations and has long been
used as a rule.
