Factors in Natural Selection Variation exists within every population
Competition Organisms produce more offspring than can survive There is a struggle for survival
Adaptations Traits that help an individual better survive in a particular environment
An organism does not change because of need or desire to survive. It already has the variation. Those that don’t have the variation, will NOT survive.
Survival of the fittest Some organisms are more fit for their environment Ex: Peppered Moth
Natural Selection Overtime, the traits that allowed individuals to survive and reproduce, those traits become more common in the population
Natural Selection at Work Many colors already exist Orange and yellow m & m’s are camouflage against the candy corn!
If m&m’s could reproduce……. Eventually, we would see more & more yellow and orange m & m’s in the population Individuals best fit for their environment will survive & reproduce
Decent with Modification Evolution Each species has descended, with changes, from other species over time Genetic change in a population over time
