Natural Selection
Natural Selection1. Variation: There is Variation in Every Population.2. Competition: Organisms Compete for limited resources.3. Offspring: Organisms produce more Offspring than can survive.4. Genetics: Organisms pass Genetic traits on to their offspring.5. Natural Selection: Those organisms with the Most Beneficial Traits are more likely to Survive and Reproduce.
The order is not that important. The fact that all of the steps are intertwined IS important!
