Mutations cause different phenotypes that can be passed from parents to offspring
The most fit individuals in a population - those with
adaptations - Survive to pass on their alleles to offspring
Environments have limited resources such as food, habitat,
mates
more offspring are bom than can survive
.: The potential for populations or a species to increase in number
:: Genetic variation of individuals within populations
:: Competition for limited resources within the environment that individuals need to survive and reproduce
The proliferation of organisms that are better able to survive and reproduce in that environment
