It is therefore scientifically correct to say that 'natural selection has been proved to be an agent of evolutionary change' - we can, in fact, prove it by doing. But it is totally illegitimate to claim that the discovery of this mechanism - natural selection - proves that the cause of evolution 'was automatic with no room for divine guidance or design'.
