Phylogeny of Y-chromosome haplogroups and languages family
The E1b1b lineage with the Afro-Asiatic languages The most commonly cited genetic marker in recent decades has been the Y chromosome, which is passed from father to son along paternal lines in un-mixed form, and therefore gives a relatively clear definition of one human line of descent from common ancestors. Frequency of haplogroup E1b1b in select Afro-Asiatic speakers Several branches of humanity's Y DNA family tree have been proposed as having an association with the spread of Afroasiatic languages. 1. Haplogroup E1b1b is thought to have originated in Horn of Africa. In general, Afroasiatic speaking populations have relatively high frequencies of this haplogroup, with the notable exception of Chadic speaking populations. Christopher Ehret and Shomarka Keita have suggested that the geography of the E1b1b lineage coincides with the distribution of Afroasiatic languages. [1] 2. Haplogroup J1c...
