Animal behaviour, evolution, and neuroethology are studied. It seems clear from the biological literature summarised here that this is not the case. Behavioural mechanisms for thermal regulation are ubiquitous and can be a significant component of an animal's lifestyle. Small animals can change their body temperature more rapidly than larger ones, so can suspend or resume thermoregulation relatively rapidly.
Thermal considerations can even influence macroevolution.
Such population dynamics cannot be understood without considering animals' responses to temperature. It can be concluded that there is a wide range of biological phenomena within the scope of ALife which can only be fully understood with reference to animals' thermal responses.
