Back

To be able to eat the food readily available in the environment.

Front

Why are advantageous traits more likely to be passed onto offspring?

Back

Because they are more likely to survive and reproduce.

Front

Why would a population with a large amount of genetic variation be more likely to survive a severe climate change in its environment?

Back

Some individuals will possess traits better suited to the new climate and be more likely to pass them on.
