| The timing of endothermy in the development of altrical birds. |
| Two evolutionary events that shaped current vertebrate life were the transition from water to land, and the development of endothermy. |
| That complex scenario, involving endothermy and preadaptations, has no name as yet. |
| Some dinosaurs may have been so endowed, and although they seem to have possessed the cardiovascular system necessary for endothermy, that capacity does not conclusively prove that they were endothermic. |
| Hair for insulation is a correlate of endothermy, the physiological maintenance of individual temperature independent of environmental temperature. |
| Toward the end of the reign of dinosaurs, some animals, the future mammals and birds, evolved endothermy. |
