Darwin’s process of natural selection has four components.
- Variation. Organisms (within populations) exhibit individual variation in appearance and behavior.
- Inheritance. Some traits are consistently passed on from parent to offspring.
- High rate of population growth.
- Differential survival and reproduction.
