NettetNatural selection occurs if the following 4 criteria are met. Overproduction, a species produces more offspring than will survive to maturity. Genetic diversity, individuals within the species population are genetically slightly different from each other. Struggle to survive, individuals of a population must struggle to access resources;such as ... NettetBecause natural selection can produce amazing adaptations, it's tempting to think of it as an all-powerful force, urging organisms on, constantly pushing them in the direction of progress — but this is not what natural selection is like at all. First, natural selection is not all-powerful; it does not produce perfection. It’s all about getting NettetNatural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift.

NettetEvolution is not the same as adaptation or natural selection. Natural selection is a mechanism, or cause, of evolution. Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations. Random mutations are the initial cause of new heritable traits. NettetLike colors that are bright enough but not too bright. Natural selection can also help to maintain diversity, where some individuals are bright, some are dull, and some are in between. Because environments are always shifting, it can be helpful for a population to have individuals with a range of trait variations.
