How does natural selection change population
WebNatural 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. WebNatural 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. It does not create anything from scratch.

WebExplain the four steps of evolution by natural selection. First, populations reproduce more offspring than can possibly survive in an environment (overproduction). Next, the offspring vary in their characteristics. And, much of this variation is genetic (variation). WebNatural selection may arise from differences in survival, in fertility, in rate of development, in mating success, or in any other aspect of the life cycle. All such differences result in natural selection to the extent that they affect the number of progeny an organism leaves.
