Shared derived character def
WebbIn phylogenetics, an apomorphy (or derived trait) is a novel character or character state that has evolved from its ancestral form (or pleisomorphy). A synapomorphy is an apomorphy shared by two or more taxa and is therefore hypothesized to have evolved in their most recent common ancestor.

WebbShared derived characters. Shared derived characters are the main evidence for phylogenetic relations. All the characters shared between species can be divided into three types: • A first division is into homoplasies and homologies: a homology is a character shared between species that was also present in their common ancestor; a homoplasy … WebbSynapomorphies and autapomorphies are both types of apomorphies, or derived characters; the difference between them is whether they are shared among taxa (synapomorphies) or not (autapomorphies). Autapomorphies are present in only one of the terminal taxa included in an analysis.
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. WebbThe cladistic method interprets each shared character state transformation as a potential piece of evidence for grouping. Synapomorphies (shared, derived character states) are viewed as …
