• Evolution acts on populations rather than on individuals.

• The Hardy-Weinberg Principle depends on a finite population, no mutations, no migration, and no genetic drift.

• Cooperation can improve the state of a population even though competition and natural selection would seem to favor those that are selfish.

• Group living has benefits and costs but for some species, the benefits outweigh the costs.

• In finite populations, there is greater genetic drift, a greater chance of a decline in fitness, and a loss of the frequency of heterozygosity.
