Both lineages are thought to have been the main surviving lineages involved in the out of Africa migration (or migrations) because all indigenous lineages found outside Africa belong to haplogroup M or haplogroup N.
Yet to be conclusively determined is whether the mutations that define haplogroups M and N occurred in Africa before the exit from Africa or in Asia after the exit from Africa.
In particular, it is often taken to indicate that it is very likely that there was one particularly major prehistoric migration of humans out of Africa, and that both M and N were part of this colonization process.
There is a debate concerning geographical origins of Haplogroup M and its sibling haplogroup N.
