^Sorry, by sentence I ment post.
Continuing my train of thought on this matter, it would make more sense if a fish and a lizard were cousins, than a lizard being a direct decendant of a fish. Somone please correct me if im wrong though. It just seems to me that it works out better for the laws (or at least how Ive interpreted them) if there was a single type of creature way long ago who had some offspring which went on to mutate into what is now crustaceans, some of its offspring mutated into Fish, some mutated into amphibians, and from the amphibians into terrestrial lizards? Rather than a lizard coming from a fish. If they were all descended from one central creature, million of years ago, it would explain how they can have traits today which bring them together, and have developed further mutations such as the diverse species, and labryinth organs. Im just thinking online now though.
And congratulations most of everyone on remaining fairly mature through 14 pages of posts.

NinjaChibi said: Sure they show me a fish and then another species of fish with some different lungs. But still the lungfish is still a fish. It isn't a lizard. It`s STILL the same species just a different variety.
I feel I must point out that you contradicted yourself in that sentence. A lungfish cannot be both "another species of fish" and "STILL the same species just a different variety". The only time that a different variety occurs within a species is as a breed. This also almost always only occurs in domesticated animals such as the horse, cat, rabbit and dog which have developed recognizable breeds through selective breeding (and unfortunately culling) performed by humans.

The lungfish is a seperate species, but is a member of the same KPCOFG as mulitple other living beings. i dont know how far up the chain a fish becomes a lizard cousin though.

If you want a practical exmple of evolution at work, one that was well documented and has undeniable proof, try the peppered moth story. http://en.wikipedia.org/wiki/Peppered_mo... It went from white, to black, and then to white again. You may argue that one of those was caused by 'less genetic information`, but the reverse also happened, so somewhere, genetic information had to be added. That`s my rant. Thank you and goodnight.

Thus, the population's ears would get pointier and pointier on average over succesive generations. Now imagine the opposite, pointy ears become a sign of the devil or some such. All my descendants are hunted down and killed. No more pointy eared babies, problem solved. This is how the environment can select for certain traits, and eliminate others. The main factor is change in the environment. And if you need a practical example, think about that one lucky lady a LONG time ago that had slightly larger breasts than average. Now, the average breast size in the world is growing steadily. Evolution at work, people.
