Origin

Haplogroup D is believed to have arisen in Asia some 48,000 years before present.[2] It is a descendant haplogroup of haplogroup M.

Distribution

It is found in Northeast Asia (including Siberia). Its subclade D1 (along with D2 and D4) is one of five haplogroups found in the indigenous peoples of the Americas, the others being A, B, C, and X.
Haplogroup D is also found quite frequently in Central Asia,[3] where it makes up the second most common mtDNA clade (after H). Haplogroup D also appears at a low frequency in eastern Europe and southwestern Asia.

Subclades

There are two principal branches:

Popular culture

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