Haplogroup R (Y-DNA)

Common card · No. 321546

Haplogroup R, or R-M207, is a Y-chromosome DNA haplogroup. It is both numerous and widespread among modern populations. Some descendant subclades have been found since pre-history in Europe, Central Asia and South Asia. Others have long been present, at lower levels, in parts of West Asia and Africa. Some authorities have also suggested, more controversially, that R-M207 has long been present among Native Americans in North America – a theory that has not yet been widely accepted. Haplogroup R originated about 31,900 or 35,000 years ago. According to Bergstorm et al, ancestors of haplogroup R and Q (Y-haplogroup K2b2/root P) split in Southeast Asia near Sahul.
