Question

All of these choices are correct.

A) Molecular clocks use genetic divergence to estimate the time since species separated.
B) Different genes can have different mutation rates, affecting the speed of molecular clocks.
C) Pseudogenes have rapid evolution rates because they lack selective pressure to maintain their function.
D) Negative selection can remove deleterious mutations and slow down the rate of evolution.
