Document Summary
Hardy-weinberg also assumes random mating with respect to genotype: but mating is often non-random. Non-random mating perturbs hwe, but doesn t cause evolution: homozygous individuals mate amongst themselves to create whatever amount of individuals they started with. Why evolution is true: humans evolved from earlier species of animals . Survey to the world indicated countries that believe evolution is true. United states and turkey have the least percentage of individuals. Evolution is only a theory : an assumption based on limited knowledge a conjecture , a coherent set of testable hypotheses that attempt to explain facts about the natural world . What is the theory of evolution: 1. Change in allele frequencies in a population, between generations. May be due to genetic drift, natural selection, etc: 2. Small changes over time gradually evolve into a different organism. Viruses and diseases can go through evolution like this, however may be a little quicker: 3.
