a. One
8. If organisms A, B, and C belong to the same class but to different orders and if organisms D, E,
and F belong to the same order but to different families, which of the following pairs of organisms
would be expected to show the greatest degree of structural homology?

10. The figure contrasts the "Within the artiodactyls" origin of the whale lineage with the "Without the
artiodactyls" origin of the whale lineage.
What can be properly inferred from the figure?
a.
