Heredity – Natural selection is one of the four basic premises of evolutionary theory, alongside mutation, migration and genetic drift. Natural selection works on populations with a variation in traits, such as coloring.

It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.Darwin's concept of natural selection was based on several key observations: Traits are often heritable. In living organisms, many characteristics are inherited, or passed from parent to offspring. (Darwin knew this was the ... More offspring are produced than can survive. Organisms are capable of ... Natural selection is one of the ways to account for the millions of species that have lived on Earth. Charles Darwin (1809-1882) and Alfred Russel Wallace (1823-1913) are jointly credited with coming up with the theory of evolution by natural selection, having co-published on it in 1858.

Evolution is not the same as adaptation or natural selection. Remember: natural selection is a cause of evolution. Terms like “progress” or “improvement” are not a part of the definition of evolution because evolution is context dependent. Imagine a scenario where one trait might be highly advantageous in one environment, but highly ... Apr 9, 2009 · Natural selection is one of the central mechanisms of evolutionary change and is the process responsible for the evolution of adaptive features. 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 ... Darwin's theory relied on natural selection as the only known mechanism. One of these different mechanisms, genetic drift, could even match the importance of natural selection in the overall view of evolution.

Natural selection can only work on existing variation within a population. Such variations arise by mutation, a change in some part of the genetic code for a trait. Mutations arise by chance and without foresight for the potential advantage or disadvantage of the mutation.Vocabulary English naturalist Charles Darwin developed the idea of natural selection after a five-year voyage to study plants, animals, and fossils in South America and on islands in the Pacific. In 1859, he brought the idea of natural selection to the attention of the world in his best-selling book, On the Origin of Species.
Mutation means a change in DNA through, for example, substitution or insertion [of nucleotides]. First you have to have change, and then natural selection may operate or may not operate. I say mutation is the most important, driving force of evolution.

An ecosystem consists of a c 1st step of natural selection. More offspring are produced than can possibly survive therefore there is overproduction. 2nd step of natural selection.

Animals inherit their genetics from their parents or ancestors, and the environment is constantly changing. So, no organism is perfectly adapted to its environment. Thus, natural selection is constantly influencing the evolution of species. Darwin’s process of natural selection has four components. Variation.
