Endothermy and activity in vertebrates.

A F Bennett, J A Ruben

    Science (New York, N.Y.)
    |November 9, 1979
    PubMed
    Summary

    Endotherms, or warm-blooded animals, have significantly higher oxygen consumption than ectotherms, enabling greater sustained activity. This enhanced aerobic metabolism was crucial for the evolution of endothermy.

    Area of Science:

    • Comparative physiology
    • Evolutionary biology

    Background:

    • Endothermic vertebrates exhibit higher resting and maximal oxygen consumption compared to ectotherms.
    • This metabolic difference supports a broader range of sustained activity in endotherms.

    Purpose of the Study:

    • To highlight the metabolic disparities between endotherms and ectotherms.
    • To underscore the role of aerobic capacity in the evolution of endothermy.

    Main Methods:

    • Comparative analysis of metabolic rates.
    • Review of physiological data across vertebrate classes.

    Main Results:

    • Endotherms demonstrate five- to tenfold higher oxygen consumption than ectotherms.
    • Ectotherms rely more heavily on anaerobic metabolism during activity.

    Conclusions:

    • Increased aerobic capacity is a key evolutionary adaptation for endotherms.
    • Metabolic differences fundamentally shape the activity patterns and evolutionary trajectories of endotherms and ectotherms.
