Allen"s rule- very cold environments= less surface area= shorter statue= more thermal retention. Very hot environment=more surface area= longer statue=less thermal retention. Inuit- traditionaly diet is high in fat and low in vegetation, as they hunt what is available to them. Walrus, seal and polar bear are more often eaten, much of pelt and bones repurposed int tools.
