If a certain variation provides an advantage for an individual or inter-breeding group they these individuals will survive and breed where all others will die.

Well, it almost certainly would not be the same. Natural selection is when one organism in its species population chooses to mate with another organism in that species population because it is more fit for that environment.

Natural selection plays a role in the origin of new species. What is a species? Genetic drift is very different from possibility number two, natural selection, which is a much more consistent, predictable, dependable change in the proportion of one gene vs.

Antibiotic resistance also illustrates natural selection. The apple maggot fly evolved in response to change in available food. Can natural selection select for future needs of a species? How does natural selection drive evolution?

It is the one process that is responsible for the evolution of adaptations of organisms to their environment. In the Causes of Speciation section, students should look at all of the subsections listed on the left hand side of the page.
