question: Animals with better fitness have a better chance of passing their genes onto the next generation, this process is known as?
distractor3: fitness selection
distractor1: survival selection
distractor2: natural evolution
correct_answer: natural selection
support: Like the animals pictured above, all animals have behaviors that help them achieve these basic ends. Behaviors that help animals reproduce or survive increase their fitness. Animals with greater fitness have a better chance of passing their genes to the next generation. If genes control behaviors that increase fitness, the behaviors become more common in the species. In other words, they evolve by natural selection.
