Dating single gene trees in the age of phylogenomics

Dating evolutionary trees is a critical task that allows us to connect biological history to ecological and geological events, helping us explore connections between environmental change and genetic innovations.The central idea behind these techniques is to link changes at the sequence level to divergence times, under the general assumption that substitutions accumulate steadily over time.So, sequences that diverged earlier are expected to be more different than sequences that diverged more recently.For a number of biological and
