Document Summary
Binomial nomenclature: each species is assigned a 2-word name. Developed by c. linnaeus: first word is the genus & second word is species. Homologous structures: morphological similarities due to common ancestry. Analogous structures: similarities that are not due to common ancestry, indicate similar solutions to a common problem, usually due to convergent evolution. When 2 organisms develop similarities as they adapted to similar environmental. Cladograms: visually depicts a phylogenetic tree between groups, highlights the patterns of shared characteristics, homologous characteristics or molecular similarities, clade. Group of species that include an ancestral species and all of its descendants. 7 levels of order: kingdom, phylum, class, order, family, genus, species. Domains (kingdoms: in this model, k. monera is split into 2 kingdoms, k. monera is separated into: Consists of k. fungi, k. plantae, k. animalia: much of k. protista has been classified into eukarya. Domain eukarya: eukaryotes, superkingdom - incorporates 4 of the kingdoms from the kingdom model.
