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. Tandy Warnow. The University of Illinois at Urbana-Champaign. Brief history.

Cladogram - branching pattern only. Phylogram - branch lengths are estimated and drawn proportional to the amount of change along the branch. Haeckel’s evolutionary trees are among the first attempts at phylogeny inference.. Darwin’s tree. Schools of thought. A. Evolutionary Taxonomy. The basic view was that the best way to reconstruct the phylogeny of a group is to spend a lifetime learning everything one can about the biology of the group.. Section 1.3. Learning Goals. We are exploring modern classification of species using phylogeny.. We are learning to use phylogenetic trees to identify common ancestors..

Moss Systematics and Temperate Rainforests. Mosses are non-vascular. Remain small and grow in wet places. They give the temperate rainforest its lush, rich, verdant appearance. Objective.
