Answer

Brief Explanations:

Natural selection requires heritable variations in traits. These variations allow some individuals to have a survival and reproductive advantage. Traits improved during an organism's lifetime are not relevant as they are not heritable. Equal survival probability for all offspring would not drive selection. There must be more offspring than the environment can support to create competition.

Answer:

heritable variations for some traits
