In an article in the eSkeptic, Who Designed That? Creationism v. Intelligent Design, Tom McIver debunks the professed disconnect between ID (Intelligent Design) and religion. He is at once serious,
All creationist arguments inevitably lead to entanglements with religion and theology with questions regarding the designer’s identity or nature. They result in discussion about the intent of the designer, why ID designed things the way they are. Why sub-optimal design, like human weak knees and bad backs? Why apparent cruelty, such as evidenced by the ichneumons? Why parasites? Why death at all? If a designer is responsible, these all lead to religious rather than scientific responses. We have seen, with respect to predators and parasites, that whatever the response, all creationist explanations end up either confronting or conspicuously avoiding the problem of evil: a religious and theological issue.
Even single species could be designed by more than one entity. The following joke, which I first heard on Garrison Keillor’s Prairie Home Companion, suggests either imperfect design or competing designers: Three engineering students were arguing about who designed the human body. One insisted that the human body must have been designed by an Electrical Engineer because of the perfection of the nerves and synapses. Another disagreed, and exclaimed that it had to have been a Mechanical Engineer: “The system of levers and pulleys is ingenious.” “No,” the third student said, “you’re both wrong. The human body was designed by a Civil Engineer. Who else but a Civil Engineer would have put a toxic waste line through a recreation area?” Maybe the most logical conclusion is that the human body was designed by a committee of engineers!
Uh oh, a committee? That's bad news folks! Since when do committees produce good stuff?
