Please, this BIOLOGY question is A LOT of points on my test. Thank you. Species of crocodiles alive today are much smaller than in previous eras of the earth. An early theory as to why crocodiles became smaller was centered around limited food availability, a newer theory now suggests climate temperatures could be an important factor. For this problem, we will examine the food scarcity theory.

Explain how crocodiles might have changed over time based on the theory that there was limited food availability. Include in your explanation of change how Natural Selection may have played a role, including all four requirements of Natural Selection (Variation, Heritability, Overproduction, Reproductive Advantage)
