'''Natural selection''' is the mechanism in which members of a population exhibiting a specific phenotype that have a reproductive advantage over other members of the population based on the current selection pressures produce more viable offspring giving the next generation a higher percentage of the "favorable" phenotype. This principle was first observed by [[Charles Darwin]] and Alfred Russel Wallace, who noted that organisms which were better adapted to their environment tended to survive longer and reproduce more than less well-adapted organisms. They predicted that over time favorable traits which are inheritable would become more common.

According to the [[theory of evolution]], it is through a combination of natural selection and [[mutation]] that biological complexity and adaptation arise from earlier generations of life. This view is disputed by advocates of [[Intelligent Design]]. See also [[Creationism]].
