All mtDNA haplogroups found outside of Africa are descendants of either haplogroup N or its sibling haplogroup M. M and N are the signature haplogroups that define the out of Africa migration and the subsequent spread to rest of the world. The global distribution of haplogroups N and M, indicates that very likely, there was one particularly major prehistoric migration of humans out of Africa, and both N and M were part of the same colonization process.
There is widespread agreement in the scientific community concerning the African ancestry of haplogroup L3 (haplogroup N's parent clade).
