Document Summary

Taxonomy and phylogeny of animals & animal architecture. Topic 1: outline taxonomy and phylogeny of animals (chapter 4: classification & relationships, modern phylogenetic systematics cladistics, sources of information, animal classification and relationships. Carolus linnaeus (1707 1778: developed our current scheme of classification. Based on morphology comparative approach (comparing forms of animals) Binomial nomenclature latin names, genus and species epithet. Species epithet can be re-used for different animals: e. g. Aedes aegypti and anopheles aegypti: seven mandatory ranks in which you categorize the organisms. Kingdom, phylum, class, order, family, genus, species. King philip came over for good soup. When we talk about classification, we are talking about phylogeny. Phylogeny history of development of species or other group. Characters organismal features used to construct a phylogeny or evolutionary tree. Homology character similarity resulting from common ancestry. Homoplasy non-homologous character similarity, misrepresents common ancestry: orga(cid:374)is(cid:373)s i(cid:374)ha(cid:271)iti(cid:374)g the sa(cid:373)e e(cid:374)viro(cid:374)(cid:373)e(cid:374)t, do(cid:374)"t have sa(cid:373)e a(cid:374)(cid:272)estry (cid:271)ut they develop same characters through evolution, e. g. shark and dolphins;
