I was not aware Thomas aquinas was an evolutionist, Dave. Do you have a quote from him please ,that demonstrates that .         I see a TV programme that had john Mackey talking in a church not far from me .   Dawkins turned up and sat in the audience with his TV Entourage. Seems he did,nt challenge him in the meeting but after made some assertions to which I thought McKay answered well.   I have no idea whether he had declined debate with polkinghorne , but I do know Dawkins won't debate qualified scientists , creationists who might be considered equal , but you often see him on YouTube taking on what might be called easy targets.       Basically ,your definition of who serious scientists and theologians is self serving, ie, who agree with your view, or at least are not YEC,s however highly qualified.
