What is the principal theory of how evolution works.

In biology, evolution is the change in heritable characteristics of biological populations over successive generations. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations.

Do remember that Mendel provided the mechanism which made Darwin’s theory of natural selection work. Thus, do remember that Darwin and Mendel are two equal giants.Darwin's theory of evolution by natural selection is based on four observations about the natural world. One of these is that each individual has a combination of traits that makes it uniquely different. Darwin recognized that much of this; Explain the theory of evolution and give an example.

Evolutionary theory accurately describes several other elements of the discovery process. One is the literal growth of each new development in science from previous discoveries. Every discovery builds on previous discoveries. If necessity is the mother of invention, then existing discoveries are the fathers.evolution. Evolution is considered a unifying theory of biology.

Charles Darwin was the first person to give the world strong reasons for believing that plants and animals had evolved.

Variation. In evolution, the fate of an individual depends on which features it has. Each human, for example, inherits a unique combination of thousands of different features, such as eye color, blood type and sensitivity to certain tastes. Some variants, or versions of a feature, may help an organism to survive. Others may be harmful. The evidence for evolution. In this article, we'll examine the evidence for evolution on both macro and micro scales. First, we'll look at several types of evidence (including physical and molecular features, geographical information, and fossils) that provide evidence for, and can allow us to reconstruct, macroevolutionary events.
