Al,

I think there may in the future exist a solution to
the problem with autosomals, and that is autosomal
blocks of STR and SNP's, a autosomal block is genes
very close to each other on a autosomal chromosome and
its unlikely (because they are so close) that they
will be split by recombination. If you can have a
number of autosomal blocks similar to a Y-STR of
12/25/37/67 or more markers for example it would be
much much easier to follow a autosomal block back in
time to a common ancestor to a specific geographic
area making a very good biographic test that also
could work with almost any level of admixture.
Unfortunatly the science of this appear to still be in
its earlys stages.
