1) Inheritance: When the offspring gets genes/traits from their parents2) Overproduction: When that species has too many offspring and there isn't enough resources for everyone3) Survival of the fittest: When a challenge comes, the ones with the genes that will help them survive, survive4) Differential Reproduction: When they have babies with different information and genetic make up making them different
