"Since energy input is required for evolution can I assume that energy is in the form of heat since, other than kinetic energy of wind and wave or perhaps the potential energy of falling objects, I doubt any other kind existed back in olden times."
So long as you include radiant energy as heat.
"Also, since the change in entropy [delta S] is defined as [delta Q, the heat added] divided by the absolute temperature [T], is it fair to assume that the entropy of whatever organism received heat is increased?"
I'll go along with that.
