Webb12 sep. 2024 · Using shared derived characters A shared character is one that two lineages have in common, and a derived character is one that evolved in the lineage leading up to a clade and that sets members of that clade apart from other individuals. Shared derived characters can be used to group organisms into clades. 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, …

A synapomorphy is an apomorphy shared by two or more taxa and is therefore hypothesized to have evolved in their most recent common ancestor. WebbSpecies that evolve share some, but not all, traits with their ancestors. To establish phylogeny, scientists must distinguish shared derived characters from shared ancestral characters. Shared derived characters are unique to a specific clade. Shared ancestral characters are found in the clade under study as well as older clades.
