Answer:
C) Y
Explanation:
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.
- Y is the common ancestor of the greatest number of species, both living and extinct.
- V is the common ancestor of the fewest number of species.
- Eleven Species are both living and extinct, are depicted in this tree
- Evolutionary trees such as this are properly understood by scientists to be a hypothesis.
- Lamarck and Wallace are the two scientists below would probably have agreed with the process that is depicted by this tree.
