Variations in a population exist and those variations are inherited.

Living things tend to produce more offspring than can survive.

The ability to change their bodies to fit the environment.

The best luck.

The biggest body.

Darwin called the ability of an organism to survive...

Variation

Fitness

Overproduction

Adaptation
