A useful change occurs in an organism but it is not in reproductive cells. What will be its importance in evolution?
Answer and explanation
Correct answer: It will have limited importance in lasting evolution because it will not pass to offspring
Evolution is a change in inherited characteristics of populations over successive generations. A change in body cells, such as stronger muscles produced by exercise, may help that individual but normally does not alter the genes in its reproductive cells. Therefore it is not passed to offspring and has little direct importance in long-term evolution. A useful trait can spread evolutionarily only when its information is heritable and reproduction transmits it.
