Roaches have been living on earth for an amazing amount of time. If the second law was driving evolution towards more dissipative (i.e., larger, warm blooded) forms of life, why has the roach stayed essentially unchanged? Clearly a larger roach or a warm blooded roach would dissipate more energy, but neither such creature exists.
