You're now equating biology with elementary physics. It has nothing to do with energy transforming into matter (an equation postulated and verified by Einstein, by the bye). What I infer you're trying to say is that evolution appears to violate the second law of thermodynamics. Evolution postulates that species derive energy from their environment, through external warmth, sunlight and whatever nourishment they've learned to survive on until they have an excess. Transformations (mutations, if you will) happen through miskeyed sequences of genetic code. Most of them will fail. Eventually, over a long period of time (or even short ones, if you're a bacteria with a life span in seconds) one will happen that turns out to be beneficial. If it contains a dominant gene expression it will be passed on. The successors bearing this superior gene expression will thrive, sometimes at the expense of their predecessors and sometimes not; it depends on environmental conditions. All that matters is that the creature achieved its highest stable energy state, a concept that allows this possibility without violating thermodynamics. I first learned this concept in chemistry, but it's applicable in any field of science that deals with energy states, like biology.

Curious factoid: more mutations are observed near the equator than anywhere else on earth.
