Plumage convergence in Picoides woodpeckers based on a molecular phylogeny, with emphasis on convergence in downy and hairy woodpeckers
Adult and juvenile plumage characters were traced onto a well-resolved molecular based phylogeny for Picoides woodpeckers, and a simple phylogenetic test of homology, parallelism, and convergence of plumage characters was performed. Reconstruction of ancestral character states revealed multiple events of independent evolution of derived character states in most characters studied, and a concent...
متن کاملHomology evolving
over 150 years, with different meanings over time for different groups of biologists. Although first used to describe ‘the same organ under every variety of form and function’, most biologists now use homology to denote hypotheses of evolutionary relationship among traits of organisms. This is justified by the fact that darwinian evolution has replaced FIDELITY TO ARCHETYPE as the explanation f...
متن کاملStrong character incongruence and character choice in phylogeny of sea stars of the Asterinidae
Historically, characters from early animal development have been a potentially rich source of phylogenetic information, but many traits associated with the gametes and larval stages of animals with complex life cycles are widely suspected to have evolved frequent convergent similarities. Such convergences will confound true phylogenetic relationships. We compared phylogenetic inferences based o...
متن کاملNUMERICAL TAXONOMIC STUDY OF THE IRANIAN SPECIES OF ALYSSUM L. BASED ON MORPHOLOGICAL CHARACTERS
The genus Alyssum L. belongs to the subtribe Alyssinae, tribe Alysseae and family Cruciferae (Brassicaceae). This genus is one of the largest genera of the family of Cruciferae in Iran, and seems to be the most problematic genus in which the boundary of certain species is not completely clear due to the polymorphism of morphological characters. The main objective of this research is to stud...
متن کاملThe semaphorontic view of homology
The relation of homology is generally characterized as an identity relation, or alternatively as a correspondence relation, both of which are transitive. We use the example of the ontogenetic development and evolutionary origin of the gnathostome jaw to discuss identity and transitivity of the homology relation under the transformationist and emergentist paradigms respectively. Token identity a...
