- ‘Thus, perhaps the commonly asked question whether dinosaurs were ectotherms or endotherms is inappropriate, and it is more constructive to ask which dinosaurs were likely to have been endothermic and which ones ectothermic.’
- ‘The papers cover a substantial range of physiological systems and numerous types of organisms, including ectotherms and endotherms, vertebrates, insects, plants, and bacteria.’
- ‘It is conceivable, therefore, that during the evolution of endothermy there existed a continuum of physiological constitutions that were intermediate to those known from typical ectotherms and endotherms today.’
