Genetic markers which differ in frequency between the ancestral populations are needed across the genome.

If we leap far enough, all the genes will be copies of one single gene in our ancestral population.

For we can know that a species is related to an ancestral population by evolutionary descent, even though the details of the transition are controversial.

All modern humans share the same origin from this single ancestral population.

All human groups are equally old, being descended from the same ancestral population.

Speciation is the lineage-splitting event that results in two separate species forming from a single common ancestral population.

Chapter four, Eden, discusses the ancestral population of modern humans in Africa.

This, too, needs to be studied regarding whether it is not just an ancestral population of a still-living species.

The report includes a novel method to estimate ancestry without accurate ancestral populations.

It is possible to trace the common direct-line ancestral populations of various peoples of the world.
