The Life of Trees
(or: Still Another Phylogeny Program)



Note:  This tool works best for R1b-L21 and subclades!  It knows the SNP structure and STR allele frequencies for L21, and may not be as effective on other haplogroups unless you include a modal and other inputs as specified in the Inputs help.
