“Logically derived from confirmable evidence, evolution is understood to be the result of an unguided, unplanned process of random variation and natural selection.”
The statement was that if it is imaginable, a person should be able to build it. I see nothing that specifies it has to have evolved.
We synthesize natural products (a result of evolution) all the time.
Now, you may disagree with this signed statement but - this appears to me as a “wedge” document from scientists/philosophers/writers that are intent on turning science from methodological naturalism towards philosophical naturalism
We understand the trajectories of objects in the solar system to be unguided and unplanned (unless you think there are angels pushing them). Was Newton therefore a philosophical naturalist? I don't think so!
