First, we'll look at several types of evidence (including physical. it doesn't tick, it doesn't have hands, and it doesn't tell you what time of day it is. The idea of the molecular clock goes back 25 years, and is seductively simple.

in light of uncertainty in fossil dating and the rates of evolutionary change, the molecular clock cannot provide high levels of precision, but when used correctly it. Every mutation, or change in the dna, represents a certain. Proposed in the early 1960s, it was first. to serve as a molecular clock, a molecule must meet two requirements:
