It was often expressed as " ontogeny recapitulates phylogeny", i.e. the development of a single organism during its lifetime, from germ to adult, successively mirrors the adult stages of successive ancestors of the species to which it belongs.
Understanding a phylogeny is a lot like reading a family tree. The root of the tree represents the ancestral lineage, and the tips of the branches represent the descendants of that ancestor.
Phylogeny helps scientists organize species or other groups in ways that represent our understanding of how they evolved from common ancestors. In a phylogenetic tree, or cladogram, the species or groups of interest are found at the tips of lines referred to as the tree's branches.
