If you have a chart that illustrates series of species with their common ancestor?

Here is an example of a chart that illustrates a series of species with their common ancestor:

```

Common Ancestor

|

V

Genus 1

|

V

Species A Species B

| |

V V

Variety 1 Variety 2 Variety 3

```

In this chart, the common ancestor is the base from which all other species and varieties evolved. Genus 1 is a descendant of the common ancestor and is in turn the ancestor of Species A and Species B. Species A and Species B are sister species, meaning they share a common ancestor that is no longer extant. Variety 1, Variety 2, and Variety 3 are all descendants of Species B and are therefore more closely related to each other than they are to Species A.
