The mutations that make us human - Understanding Evolution

WebIn evolution, fitness is about success at surviving and reproducing, not about exercise and strength. Of course, fitness is a relative thing. A genotype’s fitness depends on the environment in which the organism lives. The fittest genotype during an ice age, for example, is probably not the fittest genotype once the ice age is over.
