Nobody knows how the mechanism works, but now you expect me to know. .... I suggest that organisms respond inventively to environmental change, just as we know they respond adaptively. If I knew how they worked things out, even the Nobel Prize wouldn't be a big enough reward.-You have admitted life is complex, but your statement above glosses over the issue of inventing new biochemistry for the adaptations you say happens as, 'organisms respond inventively to environmental change'. Any advance requires new proteins among millions of possibilities, plus coordinated complexes of old proteins. So far DNA or the whole genome does not seem to contain a way to do that.
