What was one of the two primary distinctions between a "transformational" process of
evolution, as described Jean-Baptiste Lamarck, and the "variational" process of
evolution, as described by Charles Darwin?

Lamarck thought change was a result of differences acquired by members
of a group and that the changes were acquired during the lifetime of the
individual and passed down to their offspring. Darwin thought those
differences already existed and were not acquired during the lifetime of
the members of the group.
The figure shows the relationships between oldfield mice populations. Light-colored
beach populations are shown with a triangle; dark-colored inland populations are
shown with circles. Which of the following statements is consistent with this
phylogeny?
