Hardy Weinberg and Microevolution

an evolving population is one that is showing genetic change over generations, if actual ratios dont match H-W ratios, then the population is evolving

natural selection, genetic drift, gene flow

genetic frequency Cheadle to random events. Outcomes are random changes in allele frequency in either direction, reduces diversity, alleles may become fixed or lost

an event drastically cuts population size, the gene pool of survivors is random, some alleles may be lost

alleles move in and out of the population from the migration of adults, dispersal of gametes, seeds, etc. this adds diversity to population and reduces different between populations

shifts character mean value to one direction

intermediates are les fit than the extremes, so the

intermediate types more foot than extremes

aka the scientific name for species

grouping species together based on similarities

Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species (Dashing King Philip Came Over For Good Soup)

a the species in a clade share homologies

are inherited from common ancestor
