The concept of natural selection includes these observations and conclusions: By chance, heritable variations exist within a species. Species produce more offspring than can survive. Offspring with favorable variations are more likely to survive and reproduce. WebDec 29, 2024 · Evolution: Natural Selection Natural Selection Evolution, the change of species over time, is the central unifying theme of biology. Biological evolution occurs through natural selection. Natural selection is the result of overproduction of offspring having variations, these variations struggling for survival, and the subsequent survival and …

Natural selection. Natural selection is a process where organisms produce more offspring than can survive and the organisms with the best adaptations live to pass on traits to their offspring. WebFitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group).
