Instincts, do they exist?

[Unit000]

Sorry, you're right I was jumbled up there...Had other things on my mind when I was writing that. But and instinct can't be anything you learned. Then it's not an instinct. Like the first time someone throws a ball at you it hits you square in the face. An instinct is totally preprogrammed data...So anything that is learned in any way totally rules it our as an instinct. I'm kind aundecided though. Because many things people claim to be instincts are either learned from other creatures or a just simple reactions caused by stimmuli to the nerves. But An example of instinct has to involve the Great White. As you may know the Great White is born and then left alone almost immediately. But somehow they all develop the same hunting technique of cruising along the bottom and utilizing their body camouflague to ambush prey. So ruling out learning this technique leaves only one possible explanation for such a complicated manuever and that's that it knew it all along through pre-programmed data in it's brain.
