Taxonomic hierarchy - a system of classifying and naming species for the purpose of understanding and establishing relatedness between species or larger groupings Kingdom Phylum Class Order Family Genus Species What words are used to name the individual type of organism? - Genus and Species Super and Sub prefixes - used to further describe refinement of groupings above and below a certain level 3 criteria for designating species: Boys Make Pasta - biological, morphological, phylogen...

Genetic Drift - the constant changing of allele frequencies (that percentage of all alleles any one, or more, allele occupies in a population) in a population over time, due to random mating. Random Mating - has the effect of changing how frequently an allele is found in a population. GENETIC DRIFT IS RANDOM, ALWAYS DRIFTING UP AND DOWN bottlenecks - where a gene pool is significantly reduced for some reason and a relatively small allele diversity remains. Founder event/effect - a cha...

Cell Theory - All organisms are made of cells, and all cells come from pre-existing cells. Conclusion: If you trace a cell's lineage back far enough, you will discover that all cells are descended from a common ancestral cell Evolution - The heritable change in a population over time or a change in gene frequency in a population over a number of generations Proximate process - what happens in short term, measured in fractions of lifetimes Ultimate process - longer timeframe (lifeti...
