Subject: [DNA] P312 and U106 Migration Scenarios
Date: Wed, 17 Nov 2010 18:01:17 -0700

When most people take P312 and U106 haplotype collections and estimate tmrcas for the two they typically come out to be very similar and around 4000 years ago. But there is a third estimation which can and should be performed --- the node age for the MRCA ancestral to both the P312 and U106 populations. That age also comes out very close to the same 4000 years. This means there probably was not much time between the single man ancestral to both haplogroups and the individual MRCAs of the two haplogroups.

I think this makes it more difficult to sustain scenarios in which the migratory history and geographical details leading up to the two founding events and locations are excessively different from each other.

There are some constraints in place which probably favor some geographical closeness between these foundings..
