The fossil record helped to establish evolutionary relationships and estimate divergence times of the primate branch leading to humans, but not until the advent of genome sequencing technology has it been possible to learn more detail about speciation times, genetic and phenotypic divergence times, and the genetic variation present in common ancestor species.
