In my recent message about ancient haplogroup I in Europe I forgot to include a comment on phyloequivalent snps. Here it is. So you can see the importance in Tree building of keeping track of the full list of phyloequivalent snps for every branch segment of the Tree, especially as the branch segments are further upstream. As the business of recovering the most complete ydna as possible for very old bones continues, and we want to extract information from those reconstructed y chromosomes, necessarily the reconstructions will be incomplete to various degrees depending on soils and climate conditions, etc. Not all snp sites will be readable. So as complete as possible a list of phyloequivalent snps in our Tree gives the most number of alternative sites to read in the reconstructed ydna of the ancients. This will allow for more information extracted from that ancient dna for better location of the ancient dna in the Tree.

And I made a @#$%% typo. Motala2 is M253- of course.
