Answer

Brief Explanations:

Natural selection requires heritable variations in traits. These variations allow some individuals to have a survival and reproductive advantage. Traits acquired during an organism's lifetime are not passed on in natural - selection (Lamarckian inheritance is incorrect). Offspring do not have equal survival probability, and there are usually more offspring than the environment can support, which leads to competition.

Answer:

heritable variations for some traits
