How do biogeography support evolution
WebJun 8, 2024 · Biogeography is the study of geological species distribution, which is influenced by both biotic and abiotic factors. Some species are endemic and are only … 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.
