Question:
The molecular clock has limited usefulness for estimating
Last updated: 2/18/2024
The molecular clock has limited usefulness for estimating divergence times among species in part due to the saturation of DNA sequences This occurs because A DNA sequences are unable to revert back to previous allelic states B the variation in the substitution rate between closely related lineages prevents accurate estimation of divergence time C variation in population sizes among lineages changes the effect of genetic drift D in highly diverged lineages substitutions will occur at sites that have been substituted previously
