Instinct, by definition, is a hard-wired behavior. It does not have to be learned. Therefore, it is passed on from generation to generation. Therefore, it is encoded in DNA (as preconfigured neural structures?) Therefore, it is a chicken and egg problem. Does it mean that a successful (possibly essential) behavior is transcribed to DNA somehow? How can DNA aquire a map to the physical world? When you consider that an Arctic Tern circumnavigates the planet during migration, or that a salmon knows how to get back to its place of birth, I am floored as to how this behavior could have been encoded for by chance, and equally floored by the prospect of a DNA transcription process where behavior is essentially 'recorded' in DNA. Am I way off base here? Is there something simple that I am missing?
