: Constant temperature is regulated by metabolism. This adaptation conveys an
evolutionary advantage in that mammals and birds can live in environments where
ectotherms (cold-blooded creatures) would not. Being warm-blooded, however,
does have a disadvantage in that it consumes a great deal of energy and thus
endotherms have to eat more.
: Basically, the chemical reactions constantly going on in your body are what
generates the heat. Also, refer to the second law of thermodynamics.
~ Because you are one of the most thermodynamic guys I know. Never let it be said
that scientists are not a turn-on.
