Heat is a form of energy (the kinetic energy present in the vibrations of atoms or molecules). Radiant energy can be turned into heat energy. Potential energy can be turned into heat energy, nuclear energy can be turned into heat energy, electrical energy can be turned into heat energy, magnetic field energy can be turned into heat energy and chemical energy can be turned into heat energy. There is no such thing as "physical" energy (in terms of Physics). Also your use of the term "evolved" can not be applied to a changing in type of energy, the term refers to the genesis of living things.
