Final answer:
Natural selection would favor organisms adapted for surviving cold temperatures if Earth experienced another ice age.
Step-by-step explanation:
Natural selection would favor organisms adapted for surviving cold temperatures if Earth experienced another ice age. Cold-adapted organisms would have physical and physiological adaptations to help them withstand the freezing temperatures and harsh conditions. For example, they may have thick fur or feathers, a layer of insulating fat, or the ability to produce antifreeze substances in their bodies.
