Haplogroup R is a widely distributed human mitochondrial DNA (mtDNA) haplogroup. Haplogroup R is associated with the peopling of Eurasia after about 70,000 years ago, and is distributed in modern populations throughout the world outside of sub-Saharan Africa. Haplogroup R is a descendant of the macro-haplogroup N. Among the R clade's descendant haplogroups are B, U (and thus K), F, R0 (and thus HV, H, and V), and JT (the ancestral haplogroup of J and T).
