BIOL 1002 : Biology 1002 Exam 1 Review
Document Summary
Taxonomy: the branch of biology concerned with naming and classifying the diverse forms of life. Organizing: grouping things helps in dealing with them. Linnaeus: developed the foundation for modern classification, binomial nomenclature. Systematics: field of biology that uses phylogeny to categorize the diversity of living organisms. Phylogeny: perceived evolutionary history of an organism. Polyphyletic: refers to grouping which contains organisms with different immediate ancestors. Carl woese: proposed the evolutionary tree with 3 main branches. Domains: the branches on the evolutionary tree, eukaryotic, bacteria, archaea. Convergent evolution: very different organisms that have similar characteristics, ex: sharks vs. dolphins. Biological species: all organisms, which are (or have the potential for) interbreeding. Morphological species: all organisms, which have the same structure and shape, this is what people traditionally go too; look at what the organisms look like. Ecological species: ecological role, determined by the habitat occupied, based behavior. Phylogenetic species: small group of individuals that shares a common ancestor sharing an evolutionary history.
