We know that all biological systems demonstrate plan and purpose both in their being and in how they function. A plan is typically a list of processes foreseen or built in, that if followed using timing and resources, achieves some objective.
Wrong from the get go. The various structures of all biological systems are easy to arrive at by mutation and natural selection.
That's very good news for us Christians, because time and again we see really stupid designs in the animal world.
To say that God directly micromanaged every detail all would mean that God would have to be pretty bad.
One example is poor giraffe’s neck – it has only 7 vertebrae, just like it’s horselike anscestors, so it can’t easily bend it’s neck to drink. Stupid design - not to mention running a nerve 15 feet longer than a direct route would require. Our eyes are put together upside down, which gives us a blind spot. An engineer would be fired for designing an eye like that. The panda’s thumb is rigged from a deformed wrist bone – and so it can’t even bend. The Dodo had useless, shriveled wings – why “design” entire wings that serve no purpose and don’t even work? Whales grow teeth in the womb, only to reabsorb them before birth – why? It’s because they evolved from land animals with teeth, but now it’s just a stupid waste to make the teeth.
That brings up a good way to find these examples - look first at creatures that evovled in one environment, but then moved to another, like whales, sea turtles, ostriches, penguins, etc. Who but an idiot or a sadist would make sea turtles and whales have to breathe....... air?!?!?! Or lay their eggs on land?
There are hundreds of examples like this, many in the human body. For God to purposefully design this, he would have to be incompetent or cruel.
Of all the kinds of life on earth, most of them are parasites. Ouch. If you were a good god, would you design most kinds of life to be parasites?
Why design cruel things, like the wasp that paralyzes the spider, and then lays eggs on it so the larvae slowly eat the spider alive? Can you imagine what it would be like to be slowly eaten alive by worms inside your own body?
Speaking of the human body, some of the best examples come from that - and not just diseases or malfunctions. For instance, look at the idiotic design of the eye, with the nerves coming off the retina into the eye, then needing to punch a hole to get back out again! An engineer would be fired for being so incompetent a designer. Or the birth canal - why not route it out the belly, like a natural C-section? simple. Or the stupid plumbing of the prostate gland - causing urination problems? Just plumb it around the gland instead of through it. Duh. But no, we are left with these incompetent designs and others, like the throat prone to choke, the backwards freshwater kidneys (see
http://www.talkorigins.org/origins/postmonth/may05.html), "wisdom" teeth that no longer fit our evolved, shorter jaw, and so many more.
It still amazes me that the people who blame God for all of this incompetent, infernal, or incomplete design (
http://www.geocities.com/lclane2/id2.html) are those who claim to worship this God. Creationism leads to a direct indictment of God, something that Jesus himself warns us Christians to avoid.
In Christ-
