Haplogroup A (mtDNA)

In human genetics, Haplogroup A is a human mitochondrial DNA (mtDNA) haplogroup.

Haplogroup A is believed to have arisen in Asia some 60,000 years before present. Its ancestral haplogroup was Haplogroup N.

Haplogroup A is found throughout modern Asia. Its subgroup A1 is found in northern and central Asia, while its subgroup A2 is found in Siberia and is also one of five haplogroups found in the indigenous peoples of the Americas, the others being B, C, D, and X.

The mummy "Juanita" of Peru, also called the "Ice Maiden", has been shown to belong to mitochondrial haplogroup A.

In his popular book The Seven Daughters of Eve, Bryan Sykes named the originator of this mtDNA haplogroup Aiyana.
