According to Bergmann's rule, as temperature increases, body size will decrease. This is because smaller bodies have a larger surface area to volume ratio, allowing for greater heat dissipation, while larger bodies have a smaller surface area to volume ratio, making it harder to dissipate heat in warmer temperatures. Therefore, in warmer climates, natural selection favors individuals with smaller body size.
