The science of DNA has a problem; the book of instructions for life is nowhere to be found. This book suggests that DNA is all passcodes, accepting only the correct instructions to build anything from a fish to an elephant. Information flows from the species and family to build a body and mind, creating instinctive knowledge and behaviour with a control system. That same system occasionally allows information flow from mind to mind, which we call telepathy. This revelation answers unsolved questions relating to heredity, evolution and psychic experiences; making sense of life and consciousness.
