The main reason Evolution isn't a law is because it cannot be repeated and get the real results. Evolution is the change over time. In this case evolution changes an orgainism such as a finch. The finche's beakes changed over a time period so that it could survive more easily in the changed enviorment. Evolution happens to orgainism and animals because of an enviormental change like a decrease in food or maybe an earthquake. Mostly its because the normal cycle for an animal or orgainism had changed so it has to adapt or die out. This process is called natural selection-change so that a species wouldnt die out. Another
reason evolution isn't a law because it hasn't been observed and still hasn't been able to be proved. http://en.wikipedia.org/wiki/Evolution
