Document Summary
The warmer environment you are adapted to, the larger the crural index is. Recognized that body size, body proportions and climate have correlations between one another. Bergmann"s rule: body mass tends to be greater in population that live in cold environments. The bigger you are, the less skin you have for your internal mass. You can control internal body heat better if you are smaller. Allen"s rule: shorter appendages are adaptive in cold climates. Both conditions, such as being smaller and smaller appendages, result in increased body mass to surface area. This is more effective at preventing body heat loss. Mid-facial prognathism (their nose is what sticks out the most) The back of their skull are fairly flat; more common in. They have a retro-molar gap behind their wisdom teeth, there is a space. They don"t have much of a chin.
