Definition of endothermy in US English:



  • See endotherm

    • ‘Toward the end of the reign of dinosaurs, some animals, the future mammals and birds, evolved endothermy.’
    • ‘‘How did endothermy evolve in mammals?’’
    • ‘The main basis for the faster absorption of nutrients in mammals to fuel endothermy and increased activity relative to reptiles has been shown to be a much greater intestinal surface area in mammals.’
    • ‘Two evolutionary events that shaped current vertebrate life were the transition from water to land, and the development of endothermy.’
    • ‘Different lines of evidence indicate that endothermy as it is known from modern birds and mammals may not have been feasible for most, particularly larger, dinosaurs.’
