al 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. 100,000 Prese ale Which of the five common ancestors, labeled V-Z, is the common ancestor of the greatest number of species, both living and extinct? A) V
B) W
C) Y
D) Z
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.

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.
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure.
