Those that lack this fitness level, on the other hand, either do not attain the age of reproduction or bear fewer offspring than other organisms. Genetic variety in a population impacts an organism’s physical traits, which is required for evolution. Some of these features may boost other organisms, transmitting them to their progeny (Phelan, 2021). For instance, he realized that the shells of Galápagos tortoises differ considerably depending on the island they live on.
