WebForm of a trait that evolved from an ancestral form. For example, if a light-colored species of pocket mouse begins living on the dark-colored rocks of an ancient lava flow and evolves a darker coat color, we would consider dark fur to be the derived form of the trait and light fur to be the ancestral form. WebWhat might be considered primitive at one level of comparison might be considered a derived trait at another level. For example, neither modern apes or humans have a tail. If apes are compared to humans, the absence of a tail is a primitive characteristic-they share this absence because they inherited this characteristic from a common ancestor.

WebJun 15, 2008 · To better understand the early evolution of the vertebrate skull, we can use the embryos of the cyclostome species as models. By comparing the cyclostome developmental patterns with those of gnathostomes, it becomes possible to distinguish the primitive and derived parts of the developmental program as taxon-specific traits. 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.

"In phylogenetics, a plesiomorphy ("near form") and symplesiomorphy are synonyms for an ancestral character shared by all members of a clade, which does not distinguish the clade from other clades. Plesiomorphy, symplesiomorphy, apomorphy, and synapomorphy, all mean a trait shared between species because they share an ancestral species. " - Examples of primitive traits

WebIn 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..
