Shared derived character def
WebbWhat are ancestral or primitive traits in species? Primitive traits are those inherited from distant ancestors. Derived traits are those that just appeared (by mutation) in the most recent ancestor — the one that gave rise to a newly formed branch. Of course, what’s primitive or derived is relative to what branch an organism is on. WebbA 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 …

Webbshared derived characters. Shared primitive character - A character displayed in species outside a particular taxon. (In other words it is a character that is shared beyond the taxon we are trying to define) - EXAMPLE: The character of backbone in mammals is a shared primitive character; all mammals share the homologous character of a backbone. Webb16.3 Taxonomy And Systematics. Taxonomy (from Ancient Greek taxis, meaning ‘arrangement’, and nomia, meaning ‘method’) is the science of defining and naming groups of biological organisms on the basis of shared characteristics. Organisms are grouped together into taxa (singular: taxon) and these groups are given a taxonomic rank; groups …
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, …
