Outline the process of evolution through natural selection. Understanding: Natural selection can only occur if there is variation among members of the same species. 1. populations produce more offspring than can survive; 2. individuals show variation in heritable traits; 3. there is a struggle for survival, often due to competition for resources;Natural selection. Finally, the most famous mechanism of evolution! Natural selection occurs when one allele (or combination of alleles of different genes) makes an organism more or less fit, that is, able to survive and reproduce in a given environment. If an allele reduces fitness, its frequency will tend to drop from one generation to the next.component #1. over productive of off spring. ex. sea turtles lay way more eggs than survive. component #2. Genetic Variation heritable variation among individuals in a population. ex- peppered moth. component # 3. struggle of existence. excess production of offspring leads ro a struggle for limited resources. 1. Most viruses are nonspecific to the type of cells they infect. 2. To identify a host cell, a virus is able to produce cytoplasmic extensions that are able to fuse with the plasma membrane of the host cell allowing materials to pass between the host and the virus.

One component of natural selection is the fitness level of each individual in a population.

Variation – there are variations between members of the same species. Adaptation – traits that increase suitability to a species’ environment will be passed on.The essence of Darwin's theory is that natural selection will occur if three conditions are met.

Without a working knowledge of natural selection, it is impossible to understand how or why living things have come to exhibit their diversity and complexity. An understanding of natural selection also is becoming increasingly relevant in practical ...Sexual selection is not a subcategory of natural selection, as Darwin made very clear: it arises from differences in mating success, whereas natural selection is due to variance in all other fitness components. This simple delineation comes closest to Darwin's concepts and distinctions. What Darwin apparently did not clearly appreciate, however ...Nature selects the variations that are most useful. Therefore, he called this type of selection natural selection. Darwin knew artificial selection could change domestic species over time. He inferred that natural selection could also change species over time. In fact, he thought that if a species changed enough, it might evolve into a new species.

Natural selection on polygenic traits can take the form of: Stabilizing selection: Intermediate phenotypes have the highest fitness, and the bell curve tends to narrow. Directional selection: One of the extreme phenotypes has the highest fitness. John Turner/Getty Images The first of these factors that must be present in order for Natural Selection to occur is the ability of a population to overproduce offspring. You may have heard the phrase "reproduce like rabbits" which means to have a lot of offspring quickly, much like it seems rabbits do when they mate.Natural selection, process in which an organism adapts to its environment through selectively reproducing changes in its genotype.
