Evidence of Bergman’s Rule in Indigenous Inhabitants of Different Climates Essay From a layman’s point of view, Bergmann’s Rule could be quiet evident in the differences of anatomical physiques of people near the equator and inhabitants of the arctic region. Nordic and Eskimos have relatively larger body mass than the indigenous peoples of the Congo or Papua New Guinea. There are other noticeable differences as well. One of these is postulated by Allen’s rule which states that populations of a geographically widespread species living in warm regions will have longer extremities (arms and legs) than those living in cold regions. On other species, Peter Mayhew came up with the following finding that for bird species, there was a pattern on the variables associated with latitude and body size, though not ubiquitous, that would reinforce Bergmann’s Rule (Mayhew, 2006, p. 70).
