Our Phylogenetic Family Tree
A phylogenetic family tree is a branching diagram or "tree" showing the likely evolutionary relationships among various families, based upon similarities and differences in their genetic testing. The families joined together in the tree are implied to have descended from a common ancestor. All WIRTHs are desended from a common male ancestor. The tree below was prepared by Robert Gabel. Current phylogenetic trees have high variability, depending on the data and the assumptions made. New technologies such as next-generation sequencing (Big Y at FTDNA) are discovering many new SNPs on the Y-chromosome. These new SNPs should be much better at identifying sub-groups within the WIRTH project, and the end result should be a much more accurate phylogenetic tree.
