ID’s Broken Watchmaker Analogy
Should we all pack up and go home with such erudite opponents as this?
Watching Intelligent Design – Alexander Nussbaum Free Enquiry April / May 2012 Volume 32, Number 3 (edited exerpts below)
Watches are a product of intelligent design and are often used as an example of such by creationists in their beloved – and deeply misleading – analogy.
Watches are a poor analogue for living systems, as they bear one characteristic that is common in products of intelligent design but absent from the products of biological evolution. Watches tend to be engineered for performance far beyond what is needed in use. Evolved living systems never display this kind of overdesign except, arguably, in certain characteristics used for sexual selection.
Biological evolution makes use of what is already available and generally produces not optimal design, but rather design just good enough to survive. Biological evolution is a master of jerry-building, of making do, and of overlooking design flaws as long as reproduction is achieved before the system dies.
For the human brain, amazing product of evolution though it is — capable of calculus, creating computers, and even of reaching the Moon — is also a deeply flawed belief machine that is unable to shake itself of delusions like creationism.
