Can evolution theory work from a "plan" over generations ? I saw something rather interresting on TV one day, I believe it was National Geographic. or something like that. The TV program was about the historical evolution and development to animals living in the sea to then develop lunghs and feets to be able to walk up on land. What I think I saw on TV, that's I'm not realy sure about is that some marine animals develped some bone structures to later from the rear feet over generations and thousands of years. Can this really be true ? If this evolution therory of Mr Darvin should be true, shouldent the changes and that "design improvements" that were obtained be done in smaller steps so that each generation should make some benefits of each change ? I think that an evelution theory that is based on a thaught or a principle that everytning just happend as a coincidense where the stronger individuals survived, so we got some lions and some tigers, and some monkeys as well, contra the evolution therory with the buildt in long term plan behind it. I think "believing" in a evolution therory where everything happend by coincidence contra believing in the evolution theory with the long term plan behind it will be two quite different beliefs. Is there anybody that knows examples of development history of some species that has such a form that the "design changes" first can serve to give some usable improvements after generations of development ? Could the historical deveoplment of the species have happen due to some coordinated development plan behind it or has it all happened more as an result of coincidence. Is there any proven facts that can indicate that the one or the other way of seeing things might be the right one ?
