Question
Bergmann's Rule, referenced in the slides for cold-climate populations such as the Inuit, states that:
Correct Answer
Option B is the correct answer.
Detailed Explanation
Bergmann's Rule states that within a broadly distributed taxonomic group, populations and species of larger body size are found in colder environments, and those of smaller body size in warmer regions. Larger, stockier bodies have a smaller surface area-to-volume ratio, reducing heat loss.
Hint
Larger, more compact body shapes help conserve heat in cold climates.
