Subject: [DNA] Haplogroup K Polytomy
Date: Thu, 4 Dec 2008 18:15:03 -0500

Gareth recently collected a 23andMe sequence for haplogroup T (was K2)
and added it to Adriano's spreadsheet.

To the large number of samples from P (most of which are R1), we now
have samples from L, O, and T as well. I confess to being surprised
that, despite this wealth of data, we still have not resolved the
significant polytomy at K.

For those keeping score at home, in the current ISOGG phylogeny K has
ten parallel subclades (K1, K2, K3, K4, L, M, NO, P, S, and T) plus
K*. This is hugely unlikely to be the true structure of the underlying
tree.

The L, O, and T samples each introduced new Y-SNPs which may be
significant to people within those haplogroups. That there was no
corollary new data upstream of those haplogroups but downstream of K
is curious.
