Excerpt: In human genetics, Haplogroup A (M91) is a Y-chromosome haplogroup. Haplogroup A is commom among Bushmen. Haplogroup A is localized to East Africa and Southern Africa and represents the oldest and most diverse of the human Y-chromosome haplogroups. It is believed to be the haplogroup corresponding to Y-chromosomal Adam. It is common among the Khoisan people, including the Bushmen, which - together with its high diversity - suggests that it was their original ancestral haplogroup. For example, Knight et al. (2003) reported 12-44% presence of haplogroup A in various Khoisan tribes. Surprisingly, it was not found in a sample of the Hadzabe from Tanzania, who are traditionally considered as an ancient remnant of Khoisan people because of the presence of click consonants in their language. Yet it is present in high frequency in East Africa. Semino et al. 2001 found haplogroup A in ...
