Heritable variation in natural selection

WitrynaWe use the term natural selection to mean a systematic variation in fitness (survival or reproduction) among indi-viduals in a population associated with variation in a trait or … WitrynaGenetic variation, as well as changes in the environment, cause characteristics of organisms to change over time. This process of natural selection leads to the evolution of new species.

This simulation provides a useful basis for … WitrynaThe mechanism that best explains evolution is a phenomenon known as natural selection. Natural selection is the process by which certain inherited traits—such as the color of a fish, height of a person, or shape of a leaf—are favored within a population. A population is a group of organisms that mate and reproduce with one another.
