Three Ancestors

The three ancestors are Abraham, Manu, and the Yellow Emperor. They are ancestors of all of humanity and may be used as a successor to the Five Ancestors doctrine.

All lived in a similar time period

Cyclical repitition of the ancestors through history is less possible though making using evolutionary history with the doctrine unlikely

Each one has a nearly identical myth except for being set in a different location and they are used to celebrate the unity of humans

Wikipedia article
The five ancestors are the five manifestations of the Alpha in humanity. They are five avatars of which all humans are descended
