Natural Selection
Natural selection is the process where organisms that are best suited to their environment survive and pass on their genetic traits in increasing number to successive generations. At the same time, organisms that are less adapted fail to survive or multiply at a lower rate, and tend to be eliminated from the ecosystem. In other words, the fittest organisms survive and multiply. Natural selection is key to understanding how evolution works.
