Survival and Adaptation

What is natural selection?

• The process by which certain traits or characteristics become less common in a population over time, based on their impact on survival and reproduction.

• The process by which certain traits or characteristics become more common in a population over time, regardless of their impact on survival and reproduction.

• The process by which certain traits or characteristics become more or less common in a population over time, based on random chance rather than their impact on survival and reproduction.

• The process by which certain traits or characteristics become more or less common in a population over time, based on their impact on survival and reproduction.

• Traits that are not influenced by the environment.

• Characteristics or features that are only present in non-living things.

• Characteristics or features that enable an organism to better survive and reproduce in its environment.
