A phylogeny is a proposal of how organisms are related by their evolutionary history. p336 It is based on the evidence that all living things are related by common descent.The evidence for phylogeny comes from palaeontology, comparative anatomy, and DNA sequence analysis.

Porifera: Systematics. At one time, a diagnostic feature of the Porifera was the presence of spicules.As a result, certain fossil groups whose organization was consistent with that of living sponges were not placed within the phylum Porifera.

Make realistic phylogenies quickly and easily...and be confident that they will not conflict with existing taxonomic opinions. Overview. Making phylogenies is hard enough for phylogeneticists, but it's something that ecologists are forced to do more and more frequently. In biology, phylogenetics / ˌ f aɪ l oʊ dʒ ə ˈ n ɛ t ɪ k s,-l ə-/ (Greek: φυλή, φῦλον – phylé, phylon = tribe, clan, race + γενετικός – genetikós = origin, source, birth) is the study of the evolutionary history and relationships among individuals or groups of organisms (e.g. species, or populations). Ontogeny definition is - the development or course of development especially of an individual organism. .

A phylogenetic tree is a branching diagram, showing the evolution of closely-related species from their ancestor. The existence of substantial morphological variation has resulted in the description of numerous subspecies of the cosmopolitan barn owl, Tyto alba.However, preliminary studies have revealed a high degree of genetic variation between Old and New World barn owls, suggesting that the T. alba complex may consist of several species.
