WebEvolution 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. … WebNatural selection only acts on the population’s heritable traits: selecting for beneficial alleles and thus increasing their frequency in the population, while selecting against deleterious alleles and thereby decreasing their frequency—a process known as adaptive evolution.Natural selection does not act on individual alleles, however, but on entire …

Firstly, selection can only act on the available genetic variation. A cheetah, for example, can’t evolve to run faster if there is no ‘faster’ gene variant available. WebNo Perfect Organism. Natural selection is a driving force in evolution and can generate populations that are better adapted to survive and successfully reproduce in their environments. However, natural selection cannot produce the perfect organism. Natural selection can only select on existing variation in the population.
