There are two population A (N = 500) and B (N=50). Due to genetic drift, both populations will lose its genetic diversity in a generation. Such losses become magnified over many generations. After 20 generations, what will be lose its original variation?

The horizontal axis of the cladogram depicted below is a timeline that extends from 100,000 years ago to the present; the vertical axis represents nothing in particular. The labeled branch points on the tree (V-Z) represent various common ancestors. Let's say that only since 50,000 years ago has there been enough variation between the lineages depicted here to separate them into distinct species, and only the tips of the lineages on this tree represent distinct species.
In Darwin's tree of life, each fork in the tree represents ________.
