Document Summary
Diversity: number of different forms/lineage, organismal diversity, how many different species are available. Systematics: understanding/ organization, evolutionary lineages into tree, reconstructing history of lineage, system of evolution that produces the diversity we see. Animals/plants/fungi (all multicellular) = very small % of life: majority of life is micro organisms (most diverse) Bacteria = most diverse # of species. Fungi = more closely related to animals than plants! Homology: one same trait shared in 2 organisms, homologous. Same because trait is inherited from a common ancestor: ex: monkeys and humans ability of color vision is shared. Taxonomy: major taxonomic categories within the domain, eukarya linean ranks, domain (eukarya, kingdom, phylum, class, order, suborder, super family, family, subfamily, genus. Problems with taxonomy categories: new, diverse groups that arise from existing. *species (only agreed upon category: biological reality, group of organismal individuals that naturally interbreed, genetic continuity within population. Iclicker: which has a uniform biological meaning: species.
