In the previous section I described the argument that many biologists have endorsed for thinking that the hypothesis of evolution by natural selection is more likely than the hypothesis of intelligent design. This argument considers the observation that organisms are often imperfectly adapted to their environments and construes the design hypothesis as predicting that organisms should be perfectly adapted. This version of the design hypothesis presupposes a very definite picture of what God would be like if he existed.
Actually, in the previous section Sober was primarily concerned with creationism. This is made rather obvious by the chapter title. It’s as if he was writing about Creationism and then Intelligent Design burst on the scene and he had to change things up to make it appear as if the two are the same. But what’s a philosopher of biology to do?
The point here is to demonstrate how evolutionary arguments are in fact theological rather than scientific. This is admitted by a major philosopher of biology. This OP was motivated at least in part by claims by Rumraket that the genetic code ought to be perfect if it was designed. Arguing that it’s not perfect, therefore it’s not designed. To quote Sober, “This version of the design hypothesis presupposes a very definite picture of what God would be like if he existed.”
What does this have to do with actual science, if anything?
Why do biologists (and Rumrakians) require the foil of a perfect designer God in order to make their case for evolution?
What reason do we have to believe that an intelligent designer would ensure that her organisms were perfectly adapted to their environment?
What reason do we have to believe that natural selection leads to organisms that are imperfectly adapted to their environment?
