This is the KEY to Natural Selection - the organisms that have beneficial adaptations that aid in survival will get to reproduce and pass on their genes, Ex. The four steps of natural selection are - Overproduction - Variation - inherited Variations - Natural Selection It reduces the disorganizing effects of migration, mutation, and genetic drift by multiplying the incidence of helpful mutations, since harmful mutation carriers leave few or … Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which in his view is intentional, whereas natural selection is not. The following article provides information about this theory. Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809-1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce. Darwin's theory of natural selection states that nature selects organisms that have features favorable for their survival, while eliminating inferior species. Natural selection is a process by which a species changes over time in response to changes in the environment, or competition between organisms, in order for the species to survive. Natural selection is a key to the origin of new species from the existing ones. Artificial selection works the same way as natural selection, except that with natural selection it is nature, not human interference, that makes these decisions. Each step is indispensable to the process, and each has been observed either in nature, the laboratory or both.

The four steps or conditions necessary for natural selection to occur are that more organisms are born than can survive, characteristics vary within a species, variations are inherited, and differences in reproduction and survival are due to variations. 4. Natural selection, process in which an organism adapts to its environment through selectively reproducing changes in its genotype. All four of these conditions must occur for natural selection to happen. The first element of natural selection is in the natural variation among organisms. Natural selection is the differential survival and reproduction of individuals due to differences in phenotype.It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.

A story told with Adobe Spark. Reproduction is needed, to have some differences selected and other differences NOT selected. Natural Selection in Elephants Jack Casey Elephants have many physical adaptations that allow for them to live in hot places such as Africa and Asia. The five steps of the process of natural selection are variation, inheritance, selection, time and adaptation. Variation is needed, if there are going to be differences to select from. Successful Reproduction. These adapting have come about due to a process called natural selection which is when an organism survies in a certain environment it will pass on its allies which have been successful. Artificial selection is the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations. Baby sea turtles with larger / stronger front flippers may have an advanatge of getting out to sea faster than others, aiding in survival. Types of natural selection: 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,
