Investigating the Tree of Life. Legless lizards have evolved independently in several different groups. Figure 26.1. Phylogeny. is the evolutionary history of a species or group of related species. For example, a phylogeny shows that legless lizards and snakes evolved from different lineages of legged lizards. Section 1.3. Learning Goals.
