Document Summary

Lecture 7: more on natural & sexual selection. Classification ordering of organisms into categories to show evolutionary relationships: the linnean hierarchy, kingdom, phylum, class, order, family, tribe, genus, species, humans, kingdom: animalia, phylum: chordata, class: mammalia, order: primates, family: hominidae, genus: homo, species: sapiens. Taxonomy & systematics: taxonomy theory & practice of naming & classifying biological organisms, systematics branch of biology that describes patterns of organismal variation & relationships, binomial nomenclature genus & species: homo sapiens. Phylogeny & classification: classification should reflect evolutionary history of life (phylogeny, phylogenies evolutionary histories of groups of related organisms, phylogenies trace adaptations from common ancestors, the (cid:858)t(cid:396)ee of life(cid:859) is (cid:448)e(cid:396)(cid:455) (cid:271)ush(cid:455) (cid:449)/ diffe(cid:396)e(cid:374)t g(cid:396)oups e(cid:448)ol(cid:448)i(cid:374)g (cid:374)e(cid:449) adaptatio(cid:374)s. Reconstructing phylogeny: how do we trace ancestry back millions of years, look at both living & fossil groups & identify the features that group them together.
