The mesolithic line is derived for some of snps which used to be phyloequivalent to M423 and ancestral to other snps which used to be phyloequivalent to M423 as seen in Geno2 data. That means the branch line leading to the some of the remains in Luxuemberg and Sweden left the tree prior to the node where lines to L161 and L621 parted ways. See "Tree and Map for haplogroup I". Since the branch line to the remains is several thousand years long, I would think there are snps unique to that branch line and not seen in any present day dna represented in our databases right now. But those unique snps would have to be looked for in the full genomes reconstructed from the 8000 year old bones. Now that I understand your "parallel" versus "not ancestral" comment, I would agree the probability of the former is just way higher than the latter, especially finding these remains several hundred of miles apart, and also after consideration of the timelines. The bones found are 8000 years old. The node where L161 and L621 branch lines part ways is estimated to be 12,000 years ago. The split of once M423 equivalent snps between ancestral and derived as seen in the bone samples is roughly 50/50. So the timing is thousands of years wrong for those bones being from people right in the common ancestral line of L161 and L621.

Or is it just so statistically unlikely that the lineage of one of these remains established the modern line? ------------------------------- To unsubscribe from the list, please send an email to [email protected] with the word 'unsubscribe' without the quotes in the subject and the body of the message
