体型越大 对应表面积面积其实越小散热的程度-体型越大程度越低代谢是立体的 表面积散热是平面的食物多才会大笑话*大型化...所以胖子 比较不怕冷我个人观点== 不要喷我我记得还有一个法则也是支持胖仔更不怕冷==In a 1986 study, Valerius Geist claimed Bergmann'srule to be false: the correlation with temperature is spurious; instead, Geist found that body sizeis proportional to the duration of the annual productivity pulse, or food availability per animal during the growing season.[33]来看一下study写什么In large mammals body size at first increases withlatitude, but then reverses between 53 and 65° N,so that small body sizes occur at the lowest andhighest latitudes. This is predicted by the hypothesis that body size follows the duration of the annual productivity pulse, so that body size is a function of availability of nutrients and energy during periods of growth. Correlations between body size and temperature are shown to be spurious. If reduction in relative surface area is indeed an adaptation to conserve heat, then mammals should increase in size from south to north at rates two orders of magnitude greater than they do. Bergmann's rule has no basis in fact or theory.太好了
