The "molecular clock" is an interesting way of measuring species divergence because
A) a reliable "molecular clock" would speed up over time.
B) a reliable "molecular clock" would slow down over time.
C) it assumes that the more similar the blood proteins of related species, the more recently they diverged.
D) it measure time which did not exist millions of years ago.

Quizplus · Accepted Answer

The molecular clock hypothesis assumes that genetic mutations accumulate at a relatively constant rate over time, allowing scientists to estimate the time of divergence between species based on genetic similarities and differences, such as blood proteins.
