What is the principal theory of how evolution works

The basic theory of evolution is surprisingly simple. It has three essential parts: It is possible for the DNA of an organism to occasionally change, or mutate. A mutation changes the DNA of an organism in a way that affects its offspring, either immediately or several generations down the line. The change brought about by a mutation is either ....

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.Although the theory of evolution generated some controversy when it was first proposed, it was almost universally accepted by biologists, particularly younger biologists, within 20 years after publication of On the Origin of Species. Nevertheless, the theory of evolution is a difficult concept and misconceptions about how it works aboundThe theory of evolution states that the diverse array of organisms on Earth has evolved from a single common ancestor over time. Evolution works through a process known as natural selection. Natural selection makes it more likely for the best-adapted individuals to survive and reproduce. Individuals who reproduce pass their traits on to …

This happens normally in the process of making a sperm or an egg. As a result, every new child or offspring inherits a unique assortment of DNA from each parent. Although both children inherited their chromosomes from the same parents, each child got different versions. Selection

And the changes may be subtle—for instance, in a wolf population, there might be a shift in the frequency of a gene variant for black rather than gray fur. Sometimes, this type of change is due to natural selection.
