We propose that mammalian homeothermy was was acquired in two steps. The first step enabled mammals to invade a nocturnal niche without an increase in resting metabolic rate. The second step enabled them to invade a diurnal niche and involved the acquisition of higher body temperatures and metabolic rates.
我们提出,哺乳动物的恒温性是分两步获得的。第一步使哺乳动物能够在不增加静息代谢率的情况下进入夜间生态位。第二步使它们能够进入日间生态位,这涉及到获得更高的体温和代谢率。
