In phylogenetics, an apomorphy (or derived trait) is a novel character or character state that has evolved from its ancestral form (or plesiomorphy). A synapomorphy is an apomorphy shared by two or more taxa and is therefore hypothesized to have evolved in their most recent common ancestor. In cladistics, synapomorphy implies homology. Examples of apomorphy are the presence of erect gait, fur, the evolution of three middle ear bones, … WebbShared traits are the traits that are shared between two or more lineages. The derived traits and ancestral traits vary depending on the organism. The Primates: Primates are a group that is present within the mammalian family. They are composed of species like lemurs, monkeys, apes, silverback gorillas, bonobos, orangutans, and humans.
