I don't reject evolution because evolution, as science has observed it, IS simple adaptation......I reject macro-evolution because it is what people like you PRETEND science says about evolution.......it has, in fact, never been scientifically proved.....nor can it ever be......
you require proof of what you yourself believe occurs through the process of evolution?.....a strain of feline enters an isolated area where it experiences a different environment.....it adapts to that environment......a different type of feline results......
interestingly, with an Intelligent Designer involved it wouldn't have to take ten thousand generations.......just the touch of a divine finger on the DNA in utero and it could happen in a single gestation......simple observation shows you how much time can be saved when a Causer gets involved.....why, just in the last five thousand years or so, some small wild feline has been adapted by human manipulation into thousands of different varieties of housecat......think of what could be accomplished by a Causer who could manipulate the DNA with a thought......
