I'm curious about the degree to which we've really established natural selection as the causative factor. For example, has the possibility that something in the pollutants is interacting with moth metabolism been eliminated?
If I'm not mistaken, (and I might be,) wouldn't the only thing you have to do to check that is remove two moths from the environment, and see if they have peppered babies?
I mean... change from pollutants wouldn't pass on to their offspring, would it?
