For toadfish undergoing disruptive selection, the extremely large and extremely small phenotypes have a reproductive advantage over intermediate phenotypes. Natural selection operates by changing the relative frequency of pre-existing alleles in the population, most often by eliminating traitsnot creating them. Blue birds usually fly the fastest. BP has more cost-efficient upstream operations, with its ten-year average upstream unit production cost ($9.46bn per barrel of oil equivalent) being roughly 18% less than that of Shell ($11.64 per barrel of oil equivalent). Convergent evolution, in which similar structures evolve independently, seems to have taken place countless times. For comparison, HIIT training burns far more calories per minute. It can drastically affect your health, especially as you reach older adulthood (9). For instance, according to NHGRI, fruit flies are 60% genetically similar to humans.
