soo if u had domesticated cows, and then u just release them into the wild, they'll get back to their original wild selves?

Obviously not at once. But over several/many generations they tend to look more and more like the wild animals they were originally bred from.

Variation due to environment can even be detected in humans. During WW1 Australia was settled almost exclusively from British and Irish stock yet Australian soldiers were noted to be generallyl several inches taller than their native English allies. The change came about in only 4 or so generations.

 A perfect example of the "wild cow" you are talking about are packs of wild dogs.  There are many packs of wild dogs that roam around and hunt and are actually more dangerous than wolves.  Just dogs that have gone back to nature for one reason or another, and/or bred with wolves.  Feral cats are also an example.
 An interesting example of adaptation to environment is frogs that change their sex due to a lack of the opposite sex.  There are frogs that will actually become fully functional females or males if facing a shortage.  Kind of an extreme example but there ya' go!
  Another interesting one is polar bears that have moved inland from lack of territory and game that are found with brown fur, (I think it was brown, not black,) as they are not in the snow anymore.  Kind of like a soldier changing his camo.

First, the cows would have to be able to survive in their new environment.  This is not necessarily a given.  Many, if not most of the traits that originally made it possible for such beasts to survive in the wild have been bred out of them.  In that at least some of the genes of their wild ancestors remain in them, if they are capable of surviving and the wild environment into which you're releasing them is similar to that of their wild ancestors, then it's reasonable to assume that they'll eventually resemble the original animal.  That's the theory.  To some it's perfectly logical, to others, hogwash.
  A Nazi scientist, Lutz Heck, did experiments in back breeding of extinct wild cattle.  The results are still very controversial:

  He also experimented with back breeding a relatively recently extinct European horse, the Tarpan:

   DNA had yet to be discovered in Heck's time, of course, so he used physical characteristics of the extinct animals as his guide.

Um luke 1. there are several creationist theory various skin tone for one adam none of them involve evolution, adam had jewish type skin, I know one family with seven kids who are predominantly hawiian, Fillipino ,and samoan (sp?), and they are like a crayon box varying from very white to very dark . Also Noahs sons split up into various parts of the world (they likely had different skin tones )  and later they adapted to their enviroment . Micro-evolution is not difficult to prove at all for instance if you worked hard enough you could easily create a new breed of dog however , macro-evoluton is quite different ,macro-evolution would be working hard for a long time to make a banana into a dog  . If you have any other questions about creationism feel free to send me a pm.

Good idea.

Wow, real live creationists.

Please understand that I don't necessarily agree that Heck brought back any extinct species.  It's just interesting that he was able to make look alikes by selective breeding.  I don't agree with or support Heck or any Nazis.
