Document Summary
Classification the arrangement or organization of phenomena into categories. Taxonomy rationale or methodology used to classify; in biology is based on similarities and differences. Phylogeny the evolutionary lineage of a group of related organisms. Evolutionary systematics an approach to the science of classification that is based on evaluation the degree of distance or closeness reflected by a suite of morphological characteristics exhibited by different groups of animals (cladistics) Phylogenetic classification the science of classification that involves a systematic examination of specific traits within organisms in order to place them within a branching pattern that illustrates their relatedness. Analogous traits traits that serve the same function but are not the result of common ancestor. Speciation concepts: biological, evolutionary, phylogenetic, ecological, recognition, cohesion. Sympatric populations share the same living space. Allopatric populations show no overlap in living space. Reproductive isolation mechanisms: behaviour, morphological, physiological, geographical, ecological. Hybrid zone is where two genetically distinct but closely related taxa meet, interbreed, and produce offspring.
