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. See more 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 See more The concept of synapomorphy depends on a given clade in the tree of life. Cladograms are diagrams that depict evolutionary relationships within groups of taxa. These illustrations are … See more The word synapomorphy—coined by German entomologist Willi Hennig—is derived from the Ancient Greek words σύν (sún), meaning "with, together"; ἀπό (apó), meaning "away from"; and μορφή (morphḗ), meaning "shape, form".

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.
WebApr 5, 2024 · Derived characteristics are traits shared by the members of a group of organisms with many similarities, known as a clade. These characteristics, however, are not shared by the ancestors of clade members.
