Document Summary
*side note: hardy wienberg works if mating is random. Effect of non-random mating on hwe and on evolution. Non-random mating perturbs hwe but doesn"t cause evolution. Non-random mating (specifically assortative) takes it out of hwe and changes the genotype frequencies but does not change allele frequencies of offspring generation to previous generation. Truth in science means that an assertion for which there is so much evidence that it would be perverse to deny it. See if observations and experiments support or contradict the prediction one makes. Theories and facts are different because theories graduate to fact-hood after repeat testing fails to falsify them. Assertions( statements) that cannot possibly be falsified are not scientific. Evolutions happens: change in allele frequencies in a population between generations. Also may occur through random processes; can be adaptive or non- adaptive. Most evolution is gradual; tiny changes through time that gradually change phenotype.
