dogs cannot become cats

Adhering precisely to the (now accepted as irrefutable fact) process of evolution, you cannot get from Dog to cat, because each represents a local maxima of the environment. Think wave peaks on the ocean, each represents a local idealised state - evolution will take the DNA towards a peak every time, but to go from Dog to Cat, you would have to move away from a local maxima, and survival of the fittest would eradicate those furthest from a peak (where the environment has scare resource). If there are no resource scarcities then the unfittest (e.g. fat americans) don't get eradicated. Its nice to know that there is now experimental evidence allowing evolution to go from being a scientific theory (experimentally shown to be accurate and peer reviewed for professional consensus) to fact (actually demonstrated in a lab)
