Description
CT is the immediate ancestor of virtually all haplogroups found outside Africa, and also gave rise to most common lineages within Africa. It splits into three main branches: C (found in coastal East Africa, South Asia, and Australia/Oceania, reflecting early coastal migrations), DE (the ancestral D and E haplogroups), and F (the ancestor of all non-African and most Eurasian haplogroups). The CT ancestor likely lived in East Africa before the Out-of-Africa migration.
Interesting Fact
The CT ancestor is sometimes called 'Y-chromosomal Adam's grandson', as it represents the branching point between lineages that remained predominantly African (DE and its descendants) and those that spread globally via the F branch.
