Bio Study Guide Exam 1 Taxa Groups of organisms Linnaean hierarchy Domain, kingdom, phylum, class, order, family, genus, species Importance of taxonomy Helpful species (medicines) and which are similar Harmful species (parasites) and which are similar/will react similarly Importance of binomial naming system Everyone can agree, it’s only two names, short and easy phenetics Way of grouping based on appearances. Not used, no evolution, but some names/clades stuck (ie reptilia) because it’s easier to just live with it than to try and change it all (does not account for convergence) Convergence Two different animals developing similar traits, not because they are related, but because they face similar challenges (ie fusiform shape, eyes in cephalopods and humans) Cladistics Use evolution to group organisms (accounts for convergence) Shows phylogeny (who evolved from who) In group Focal group Outgroup Used for comparison, just evolutionarily outside ingroup Adaption Does not occur in individuals, but in a species over generations. To make a species more fit (survive/reproduce) Teleology Thinking evolution is going toward a goal Evolution (3 types) biological/genetic change over generations
