If drift represents the default state, then selection is a perturbation from that default rather than a prerequisite for the theory's application

This last pattern of argument can be extended. Indeed, given that every natural system undergoing selection also undergoes drift, evolutionary theory is arguably applicable also to systems that undergo drift even in the absence of selection (in the focused sense). Gradually reduce the importance of focused selection in the above system of equations, that is, gradually reduce the differences between \(w_{D}\), \(w_{H}\), and \(w_{R}\). Is the point at which the values equalize so momentous that i
