Haplogroup A

This page is about the Y chromosome haplogroup A. Its purpose is to explain the genealogical and anthropological meanings of the determination.

If you are coming to this page directly, you may want to read first about haplogroups in general; you will probably need the background.

Project Members

As of this writing, Taylor Family Genes has three members in this haplogroup, about 0.2% of the total membership.

About this Haplogroup

Haplogroup A is the foundation from which all other haplogroups spring and is therefore the oldest. It is thought to have arisen about 338,000 years ago, with a 95% confidence level of 237,000 to 548,000 years. It originated in Africa, perhaps pre-dating the development of anatomically modern homo sapiens sapiens.

Members of this haplogroup may want to consider joining the DNA project for it. See http://www.familytreedna.com/public/Haplogroup_A/.

Y-DNA Values
