Document Summary
Hardy weinberg also assumes random mating with respect to genotype. Proportion of heterozygotes will decrease from generation to generation. Takes a population out of hardy-weinberg equilibrium, but not evolution. Theory in a dictionary sense = an assumption based on limited knowledge a conjecture . Theory in a scientific sense = a coherent set of testable hypotheses that attempt to explain facts about the natural world . An assertion for which there is so much evidence that it would be perverse to deny it sj gould. Theories graduate" to fact-hood after repeated testing fails to falsify them. Assertions that cannot possibly be falsified are not scientific. What is the theory of evolution: evolution happens. Change in allele frequencies in a population, between generations. Changes in gene frequency due to random processes: most evolution is gradual. Evolution worked by slight changes over a long period of time. There should be a variety of transitional forms found in fossil records.
