What evolutionary mechanism is most responsible for the variation in human skin color. natural selection. What wavelengths of light are absorbed by melanin. WebNatural selection is the most important way that evolution can take place -- but it's not the only way. Another important mechanism of evolution is what biologists call genetic drift, when random events eliminate genes from a population. Two important examples of genetic drift are founder events and the bottleneck ... WebThe founder effect is a special case of a population bottleneck, occurring when a small group in a population splinters off from the original population and forms a new one. The random sample of alleles in the just formed new colony is expected to grossly misrepresent the original population in at least some respects. [43] prefab metal buildings in ms
