Y-haplogroup A is the name given to the branches at the very root of the entire human Y-DNA tree. Haplogroup A is one of the most genetically diverse human Y clades. It is found most often in African men, particularly those peoples who have maintained in recent times a hunting and gathering way of life. However, it is sometimes observed outside of Africa, especially in the Arabian Peninsula. The Y Haplogroup A project is set up to assist project members in forming a more complete understanding of their ancestry, and to assist researchers towards the same aim. Anyone who has be confirmed or predicted by FTDNA to be in haplogroup A is encouraged to join. By combining our research and knowledge, we can achieve much.
