each carrying out a specific but limited function—work in concert to form biochemical systems. In turn, numerous biochemical systems interact in an orchestrated fashion to support the activities of even the simplest cells. A molecule’s function contributes to life processes only in the context of the entire ensemble of systems. In other words, for life to emerge, its biochemical systems must come into existence all at once, not step by step. My suspicions of what biochemist Michael Behe years later
