Evidence of Bergmans Rule in Indigenous Inhabitants of Different Climates stressFrom a laymans point of view, Bergmanns 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 portion than the indigenous peoples of the Congo or Papua New Guinea. There are other noniceable differences as well. bingle of these is postulated by Allens rule which states that populations of a geographically widespread species living in warm regions leave behind have longer extremities (arms and legs) than those living in cold regions. On other species, Peter Mayhew came up with the side by side(p) finding that for bird species, there was a pattern on the variables associated with latitude and body size, though not ubiquitous, that would reinforce Bergmanns Rule (Mayhew, 2006, p. 70).ReferencesRittner, Don and MacCabe, Timothy L. 2004, Encyclopedia of Biology, New York H.
