WebThermoregulation is often cited as a potentially important influence on the evolution of hominins, thanks to a highly influential series of papers in the Journal of Human Evolution in the 1980s and 1990s by Peter Wheeler. These papers developed quantitative modeling of heat balance between different potential hominins and their environment. WebK.C. Mendoza, J.D. Griffin, in Encyclopedia of Behavioral Neuroscience, 2010. Thermoregulation is a dynamic, homeostatic interaction between an organism’s internal processes and its external environment, to maintain a stable, physiological temperature. Among mammals, thermoregulatory heat loss behavior includes vasodilation, panting, …
