Examples of apomorphy are the presence of erect gait, fur, the evolution of three middle ear bones, and mammary glands in mammals but not in other vertebrate animals such as amphibians or reptiles, which have retained their ancestral traits of a sprawling gait and lack of fur.

WebA derived character is a trait that an organism evolves over a course of time. In contrast to this, an ancestral character is one that is acquired from the ancestors …
WebAfter they sort the homologous and analogous traits, scientists often organize the homologous traits using cladistics. This system sorts organisms into clades: groups of organisms that descended from a single ancestor. For example, in Figure 1, all the organisms in the orange region evolved from a single ancestor that had amniotic eggs.
