The following has just appeared on the R1b-U106 Group forum:
“2020 was an awful year in so many ways, but it was an unprecedented year for human paternal phylogenetic tree reconstruction. The FTDNA Haplotree or Great Tree of Mankind now includes:
– 37,534 branches with 12,696 added since 2019 – 51% growth!
defined by
– 349,097 SNPs with 131,820 added since 2019 – 61% growth!
In just one year, 207,536 SNPs were discovered and assigned FT SNP names. These SNPs will help define new branches and refine existing ones in the future.
The tree is constructed based on high coverage chromosome Y sequences from:
– More than 52,500 Big Y results
– Almost 4,000 NGS results from present-day anonymous men that participated in academic studies
Plus an additional 3,000 ancient DNA results from archaeological remains, of mixed quality and Y chromosome coverage.”
