Haplogroup A is believed to have arisen in Asia some 30,000–50,000 years before present. Its ancestral haplogroup was Haplogroup N. However, the extant diversity of mitochondrial genomes that belong to Haplogroup A is low relative to the degree of divergence from its nearest outgroups in haplogroup N, which suggests that extant members of Haplogroup A might be descended from a population that has emerged from a bottleneck approximately 20,000 years ago.

Its highest frequencies are among Native Americans, its largest overall population is in East Asia, and its greatest variety (which suggests its origin point) is in East Asia. Thus, it might have originated in and spread from the Far East.
