How might Allen's and Bergmann's rules be influenced by culture? That is, how can people of various body sizes and shapes adapt to different environments? Group of answer choices Allen's and Bergmann's rules are not influenced by culture. Humans and human ancestors have extensive histories of using material culture to adapt to various environmental challenges such as the use of different clothing for different climates. Culture does not play a role in how humans and human ancestors adapt to environmental challenges.

Step 1
Allen's rule states that in cold environments, animals tend to have shorter limbs, ears, and tails to minimize heat loss. Bergmann's rule suggests that animals in colder climates tend to be larger in size to better conserve heat. Show more…

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, cranial capacity of modern human populations, quadrupedal nature of most mammals, and larger nasal apertures of archaic humans.

1) What is Allen's rule? 2) According to Allen's rule, we would expect to find a relationship between cormic index and climate, growth, and development. A higher cormic index corresponds to relatively shorter legs, while a lower cormic index corresponds to relatively longer legs. Are your body proportions characteristic of ancestry in a cold climate (cormic index above 0.5) or warm climate (cormic index below 0.5)? 3) Are genetic adaptations to climate solely responsible for the variation observed in human body proportions across the globe? What other factors may influence an individual's relative body proportions? [HINT: Think about other topics we've discussed that influence growth.]
