The numbers in a phylogenetic tree typically represent the amount of genetic (or evolutionary) change that has occurred between the species or groups being compared. These numbers are often expressed as branch lengths, with longer branches indicating greater genetic divergence. The units of these numbers can vary depending on the method used to construct the tree.
