Show transcript
There are differences in the features of individuals of the same species, and this is called variation.
Some variation is caused by the environment (e.g. injuries) or lifestyle (e.g. exercising to grow big muscles).
Environmental variation is not heritable, it cannot be passed on to offspring.
Some variation is caused by genetic information (e.g. the instructions for making claws or camouflaged skin).
Genetic variation is heritable, it can be passed on to offspring.
