members of a population exhibiting a specific phenotype -- what in tarnation does that mean?
'''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.
