Phylogeny

• The history of descent modification and the accumulation of change over time

• An anatomical, physiological, or molecular feature of an organism that varies among taxa

• A character or trait that is newly evolved; an evolutionary innovation

• A type of phylogenetic tree that shows clades, or monophyletic groups

Character

• A character or trait that is present in two or more groups of organisms

• An anatomical, physiological, or molecular feature of an organism that varies among taxa

• A group of organisms that has an older common ancestor than the common ancestor of the group of interest, and therefore serves as a reference for evolutionary relationships within the group of interest

• A character or trait that is newly evolved; an evolutionary innovation

Derived Character
