Compared to more distantly related taxa, the DNA sequences of two closely related taxa is expected to show:
A. fewer differences because mutation rates
are relatively constant and recently diverging
species have had less time to accumulate
differences.
B. fewer differences because mutation rates
slow down during speciation events so that
recently diverging species have fewer
mutations.
C. fewer differences because mutation rates
are highly variable and it is just by chance
that recently diverging species accumulate
fewer differences in DNA sequences.
D. greater differences because mutation rates
are relatively constant and recently diverging
species have had more time to accumulate
differences.
E. greater differences because mutation rates
accelerate during speciation events leading to
greater changes in DNA sequences.
