According to evolution the environmental conditions are indeed constantly changing and that is how new species are 'forced' to transform themselves into other species. Remember natural selection and all that nonsense? One of the things that creates this constant change is differing species competing for food, etc., remember that? According to evolution this competition which occurs all the time because other species are constantly changing too, forces a sort of 'biological war' between species. Have you not read Darwin?
Another example is the Galapagos finches. The rains there are very variable. Remember the El Nino? Comes every seven or eight years? This causes constant changes and is the source of the increase and decrease in beaks in the finches. If forces them to constantly adapt back and forth. If evolution were true and these beaks changed due to mutations, they would not be able to do that. Because evolution is false and the finches's genomes are able to adapt the size of the beaks without mutation they can adapt to the periods of high and low rainfall which constantly occurs there.
