Question

Quizplus · Accepted Answer

Bergmann's rule states that within the same species of mammals, populations with less bulk are found nearer the equator while those with greater bulk are found farther from the equator. This is thought to be an adaptation to help regulate body temperature in different climates. As temperatures increase near the equator, smaller body size helps animals dissipate heat more effectively, while larger body size helps retain heat in colder climates farther from the equator. Options A and B are incorrect because they do not reflect Bergmann's rule.
