The principles of natural selection.

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.

Rather, a poor understanding of the principles of evolution and natural selection is harmful to informed decision-making by citizens. Future evolution education practices should be based on the assertion that "it is important that all literate people understand the central unifying theory of biology." (Kampourakis 2014 , p. x, italics added).Terms in this set (22) Evolutionary Psychology. the study of the evolution of behavior and the mind, using principles of natural selection.

To be an active characteristic or trait causing natural selection to take place, the trait has to have the following features: Heritability. A trait can only influence evolution through natural selection if it is passed on from parents to descendants. Functionality.

Natural selection, Darwin argued, was an inevitable outcome of three principles that operated in nature. First, most characteristics of organisms are inherited, or passed from parent to offspring.

Stabilizing Selection. If natural selection favors an average phenotype, selecting against extreme variation, the population will undergo stabilizing selection (Figure 1).

Basic Principles of Natural Selection. - Populations show a variation in traits. Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.Natural selection is arithmetic applied to differences. The principles are the same in all cases.
