Taxonomy ● Discipline on naming and describing classifying organisms ○ Provides universal language on different countries and languages ○ Prevents confusions on common names ■ Robin in Europe vs robin in North America are often different ○ Brodad to specific ■ Genus is capitalized ■ Species are in lower case ■ both italic ■ Homo sapiens ● Linnaean hierarchy ○ Domain => kingdom => phylum => class=> order => family => Genus => Species ○ mnemonic ■ Memorize it as ■ King philip came over for good soup ● Taxa on evolutionary relationships ○ Organisms grouped together ○ Share ancestry ● Limitation on taxonomy ○ Based on morphology only ■ Misleading since it converges to evolutions ■ Modern taxonomy is better informed through phylogeny ● Evolutionary trees Phylogeny ● Phylogeny = history of species or groups ○ Represented through phylogenetic trees ● Roots ○ Most recent common ancestor of the taxa ● Nodes ○ Branching points ○ One linages split into tow ● Branch ○ Evolving over time ● Tip ○ Represents of observed taxons ■ Species genus ● Sister taxa ○ Two linages ○ Share same immediate common ancestors ■ Humans and chimpanzees Traits in phylogeny ● Homologous traits ○ Inherited from common ancestors ■ Vertebrates forelimb transforms to human arms, bat wings , whale flippers ○ Analogous trits ■ Similar functions but has independent origins ● Birds wings vs insect wings ○ Ancestral traits ■ Present in common ancestors ○ Derived traits ■ Evolved later ■ Unique in lineages ● Synapomorphy - shared derived trait ○ Defined by groups ○ Hair is synapomorphy on mammals Building trees ● Parsimony principal ○ Simple explanation is the best ○ Fewest evolutionary changes are favored ■ Morphological traits (shapes, structures, flowers, skeletons) ■ Developmental traits ■ Fossils ■ Modular data ■ Behavioral traits Why parsimony matters ● How are traits evolved and if they are homologous or convergent ● Trace evolutionary events ○ Origin of adaptations ● Integration of evidence ○ Ecology ○ Morphology ○ Fossil records ○ Genetics
