David's theory of evolution (Evolution)

DAVID: I'm sorry you object to my reasonable approach, not to question God's thinking.

dhw: It is not God’s thinking but your own which I am questioning, and you have told us that your theory is not illogical so long as we do not apply human reasoning to the actual history. Are you telling us that you are divine? Why don’t you just agree with yourself and acknowledge that even though your theory defies human logic, and is one of several possible explanations of how and why evolution happened, it’s the only one you’re prepared to believe.

Please accept that I view God in change and running the show as He wishes. That is the faith you cannot accept. Remember faith jumps a chasm.

DAVID: How does a new species survive if problems are not prepared for in advance? The predators would have a feast and the newly arrived guys would be gone.

dhw: The new species is the RESULT of the old species finding solutions to the new problems. Millions of bacteria die when we invent a new killer, but they don’t all die, and the survivors eventually find a solution. (They remain bacteria, but I’m simply describing the process: organisms react to new problems; solutions are not provided in advance.) Pre-whales may have entered the water because food was scarce on land; pre-eared moths may have begun hunting by night because so many were being killed during the day. The environmental change then triggered the anatomical changes which led to speciation: marine life led to flippers replacing legs; hunting in the dark required enhanced sensitivity to sound – hence the ears.

To my knowledge, no one describes pre-ear moths. As Gould noted to his consternation, the fossil record shows giant gaps, no itty-bitty changes as Darwin assumed. You want the pipe-dream of minor adaptation morphing into new species. There is n o fossil su[port for your Darwin hope. Darwin gave us a concept of evolution with common descent, nothing more.

DAVID: […] The issue between us remains. How did that happen? Moths with ears are a slightly different new species, which requires design. Your answer for speciation is not my answer. As you have kindly noted my 'Atheist Delusion' book is a very strong argument for design.

dhw: Once more, you have forgotten that the issue here […] is your ANTICIPATION theory (as opposed to RESPONSE). As for how speciation happens, nobody knows. Your theory is that your God either dabbled or foresaw every future environmental change and/or problem, and preprogrammed the first cells with every response and/or solution, (though approx. 90% of species would be left to die). I propose (theistic version) that he gave cells the intelligence to work out their own designs. The rest of your post repeats and dismisses my theory, and glosses over the incredible complexities of your own by simply insisting that “only minds design”, which is not the issue between us. (Now bolded by dhw – see below.)

DAVID: That only minds design is exactly the issue. Advance design is required for new species to handle new problems.

dhw: Yes, design requires minds. You say only God has a mind - apart from humans - and I suggest (theistic version) that he may have created cellular minds (though of course nothing like our own). No, advance design is not required to handle new problems. You say you believe in common descent: this means that each new species is formed from existing species. When existing species are confronted with a new problem, either they solve it or they die. (New conditions may also offer new opportunities to existing organisms.) The RESULT of this interaction – i.e. the interaction only begins when conditions change - between organism and environment may be minor changes (adaptations) or major changes (innovations), though there is no clear borderline between the two.

There is a clear line. New species have clearly unexplained new features. That they fit the new requirements of their lives is not an explanation of how it happened. That is your constant plea, which is totally illogical, as illustrated below:

dhw: As above, bacteria continue to die until they find a counter to new medicines; pre-whale leg cells are restructured to form flippers BECAUSE they have adopted a marine way of life; pre-eared moth cells (I have no idea which ones) are restructured to form ears BECAUSE they have adopted a nocturnal way of life. And now I can only refer you back to my previous post, with the two theories and my comments bolded.
