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, … Webb24 juli 2024 · [ˈspiːʃɪˌiːz] Definition: A group of closely related organisms that can interbreed Every living organism is unique when you observe its morphological, anatomical, molecular, genetic, biochemical, chemical, physiological characteristics.
