The study of evolutionary relatedness among different groups of populations through comparative branching What is phylogeny? Homologous - structures that are derived from a common ancestor Mammals produce live young Presence of a tail, common in many animals dogs, monkeys etc. Shared, primitive traits (sympleisiomorphies) - shared with a previous ancestor Absence of tail in Apes, unique trait different and shared by the group Shared , derived traits (synapomorphies) - traits that depart from the ancestral condition Due to ancestry = homologous Analogous/convergent/homoplasy - structures that are similar but not evolutionarily related The wings of a bat vs. butterfly, both wings but not related
