Question

what will cause natural selection in a species? genetic variation between individuals availability of unlimited resources to individuals the maintenance of the same genetic makeup from one generation to another environmental stability

Explanation:

Natural selection occurs when there is genetic variation among individuals in a population. This variation allows some individuals to be better - adapted to their environment and more likely to survive and reproduce. Unlimited resources would not cause natural selection as there would be no competition. Maintaining the same genetic makeup across generations does not drive natural selection, and environmental stability does not directly cause natural selection as it doesn't create differential survival and reproduction pressures.

Answer:

genetic variation between individuals
