It depends in this case on the definition. If you are speaking hot/cold/tepid, these are relative terms, subjective of typical human ranges of acceptable temperatures.
As absolutes? No.
Heat as a measure of energy? Well, then it’s definitional.
Evolution =/= heat however unless it is defined properly.
When it is left open and vague, it becomes a subjective issue.
Heat (as measure of energy) has a simple definition. Its simplicity and lack of human subjective controversy (until we get down to the smaller levels of scope – smaller being relative to what we’re accustomed to), affords it a more factual status generally speaking.
But for evolution to acquire such status? A lot of internal and external debate has to settle down first.
It does not have the luxury of settling down just yet. It’s close? Yes. But not there yet, not until the hyperbole and excitement die down.
So heat is not entirely equivalent to evolution nor evolution entirely equivalent to heat. Science is social – something you mustn’t forget. It is always social.
