This group appeared around 50,000 years ago. This is an African marker that represents the most diverse of all the Y chromosome lineages. It links genetically back to our earliest days as a species and to our common ancestor Adam.
Many of the people of Haplogroup A speak ancient click languages like the Tanzanian Hadza. These groups are old linguistically, genetically and also culturally. They retain the hunter gather societies once very common in the world. Carriers of this marker are descendants of these people and as of the last two to three thousand years have been not only reduced in numbers but been forced into smaller pockets by the growth of the Bantu culture.
