WebBiogeography - Understanding Evolution. The distribution of species on Earth provides evidence that informs our understanding of both the evolution of life and the movement … WebThe key to using biological molecules as molecular clocks is the hypothesis of neutral evolution. This hypothesis states that most of the variability in molecular structure does not affect the molecule's functionality. This is because most of the variability occurs outside of the functional regions of the molecule.
