Why you keep going on that evolution is the product of chance I will never know. The facts are: mutations occur in DNA and therefor proteins and genes. Without mutations we would not have disease such as certain types of cancer or sickle cell disease. The vast majority of mutations are nuetral in that they don't have any effect on the creature. Some are harmful such as those I listed earlier in this post. Others are beneficial such as the mutations here and here as well as the lizards that had an expanded gut to digest plant matter in the link I can't find right now. These beneficial mutations come about via adaption to the environment via natural selection. Natural Selection is not due to chance. BumFluff122
That sounds like chance to me.
Look at this (Taken from Exploring Creation With Biology, by Dr. Jay L. Wile and Mariyln F. Durnell; published by Apologia Educational Ministries, Inc. Page 299-300):
Neo-Darwinism was the first revision to occur in Darwin's theory. Remember, Darwin pretty much established the theory of microevolution, but when it came around to providing evidence for macroevolution, he was stuck. When scientists began to understand genetics, they understood why he got stuck. As we said before, microevolution is simply the variation of a type within its genetic code. Macroevolution, however, is a completely different story. In order for macroevolution to occur, a species would have to add information to its genetic code. How could that happen? Well, Neo-Darwinists said that it could happen by mutation. You see, Darwin thought that all of macroevolution could occur by the normal changes that happen during the reproductive process. When scientists came to understand genetic, however, it became clear that those kinds of changes only explained macroevolution. Something else had to add information to the genetic code. That something else was mutation.
(Skip down a few paragraphs)
Of course, one big problem with this idea is that there has never, ever been a documented case of a mutation that has made an organism more fit to survive. Most mutations are detrimental to the organism. Some are only mildly harmful, and even fewer seem to be benign...........
There's more of that paragraph, but this will do. The lizard example you spoke of sounds only like microevolution, if not just simply a strengthening of the stomach; like exercising.
