Grades 8 - 12 Image On the Origin of Species English naturalist Charles Darwin wrote the definitive book outlining his idea of natural selection, On the Origin of Species. Components of Natural Selection (4 points to keep in mind) 1. Mutations is one of the major sources of heritable variation but mutations occur at random. 2. Studies of natural selection begin with a trait. 3. Natural selection is a process by which the characteristics of a population change over time. 4. Natural selection acts on …The evolutionary concepts that are most important at this level are the four essential components of natural selection — an important mechanism of evolution: Variation: All life forms vary genetically within a population. Inheritance: Genetic traits are inherited from parents and are passed on to offspring. overproduction. more offspring can be produced than can survive to maturity. genetic variation. within a population, individuals have different traits and the traits can be inherited. struggle to survive. compete for food and shelter. Differential reproduction. organisms with the best adaptations are most likely to survive and reproduce.Polygenic traits in a population often form a bell curve distribution. Natural selection on polygenic traits can take the form of: Stabilizing selection: Intermediate phenotypes have the highest fitness, and the bell curve tends to narrow. Directional selection: One of the extreme phenotypes has the highest fitness. Name and describe the four processes of natural selection, using hummingbirds as your example.

It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Natural selection remains the only well-supported mecha-nism of adaptation in evolution. New variation—the ‘‘fuel’’ on which natural selection acts—arises independently of se-lection.
