Escape from recombination makes the Y chromosome a useful tool for studying human genetic history. A unique phylogeny of Y haplogroups has been constructed using binary markers such as SNPs (single nucleotide polymorphisms), and diversity within haplogroups can be analyzed using multiple microsatellites. The time-depth of the phylogeny and geographical distribution of the deepest-rooting haplogroups are compatible with a recent African origin for modern humans. Haplogroup distributions are highly geographically differentiated, which allows past population movements to be studied, and sex-biased admixture to be recognized.
