Allen’s and Bergmann’s rules are perfect examples of natural selection’s effects on anatomical adaptations to environments in mammals. These include the limb and trunk proportions of Neanderthals.
Answer: Option C
Explanation:
In warm climates, the body shape is linear while in cold climates the shape is more circular and compact and surface area is smaller to volume ratios such effect is called Allen’s Rule. Although when in cold climates body size is large but in warm climates it is small while surface area is smaller to volume ratios in large bodies, such effect is termed as Bergmann’s rule.
Therefore, these rules are the best examples of natural selection’s effect on anatomical adaptions to the environment in mammals. And such rules fit best in extinct species and subspecies of archaic humans belong from Eurasia and forty thousands years ago also termed as Neanderthals.
