Component Type(s): Original Student Tutorial.The essence of Darwin's theory is that natural selection will occur if three conditions are met. These conditions, highlighted in bold above, are a struggle for existence, variation and inheritance. These are said to be the necessary and sufficient conditions for natural selection to occur. To say that the three conditions are necessary means ...2. Explain Natural Selection. Answer: It is a process by which the organism adapts to its environment by selectively making changes in its phenotype and genotype. The variations that increase the chances of survival of the organism are carried to the next generation and thus in the course of evolution.Figure 1. Different types of natural selection can impact the distribution of phenotypes within a population. In (a) stabilizing selection, an average phenotype is favored. In (b) directional selection, a change in the environment shifts the spectrum of phenotypes observed. In (c) diversifying selection, two or more extreme phenotypes are ...[Evidence of evolution: Grades 9-12] There is a fit between organisms and their environments, though not always a perfect fit.

It denotes Darwin’s specific view that evolution is driven mainly by natural selection. Learn more about the principles of Darwinism in this article.Fitness is a handy concept because it lumps everything that matters to natural selection (survival, mate-finding, reproduction) into one idea. The fittest individual is not necessarily the strongest, fastest, or biggest. A genotype’s fitness includes its ability to survive, find a mate, produce offspring — and ultimately leave its genes in the next generation.In later grades, students will learn that there are four essential components of natural selection — an important mechanism of evolution: Variation: All life forms vary genetically within a population.

The change in frequency of a characteristic in a population through time is referred to as evolution. In a population, the higher the proportion of organisms that reproduce without dying, the more prevalent that trait will be. Answer …The process of natural selection has 4 main components: Variation, Inheritance, Rate of population growth and survival and reproduction. Variation within a population would make some individuals have a variety of different traits like the amount of body hair, offsprings, body size or markings.

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. Explain how natural selection can result in adaptation.
