Evolution of homeothermy in mammals |
|
| Authors: | A W Crompton C R Taylor J A Jagger |
| Abstract: | 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. |
