S. Walker at Inconcinnus Sermo has posted some excellent observations about intelligent design creationism and organism behavior.

Has anyone ever wondered why intelligent design never really talks about anything but complexity and molecules or just complain about all the ‘holes’ in evolution (NOT)?

Walker continues:

How about infanticide? How would intelligent design explain infanticide? This would be a real test of the ID paradigm.

Indeed. Does intelligent design creationism predict and explain infanticide?

Evolutionary theory does. Here in Alaska, any brown bear sow with a cub will go to considerable trouble to avoid interaction with a male, because the male will frequently attempt to kill the cub. It makes sense that the bear would do this - the chances of a particular cub being his offspring are very small, so eliminating a cub almost always eliminates the genes of a competing male. It also makes the sow sexually receptive more quickly, thus increasing the male’s chances of mating. By this means males who commit infanticide make their genes more frequent in the population. In other words, in this case, the genes that make infanticidal bears perpetuate themselves in the gene pool.

What about infanticide in humans? There are many cultures in which people committed infanticide under various circumstances. Some cultures set deformed children out of doors to die by exposure. While not morally defensible in our culture, in a society in which resources are scarce, doing this makes a certain amount of perverse sense - you want to expend what little in the way of crops that you have on children who are healthy and vigorous. Evolutionary theory predicts that those parents who expend the least on children of low fitness will better perpetuate their genes. Just because a baby is lost this year, doesn’t mean you can’t try again next year, or the year after, when crops are good.

In addition to these well known forms of infanticide, other cultures have committed infanticide for other reasons. The ancient Israelites killed¹ all of the children of the city Ai in a military assault. In a society based on genetic relationships², killing all the inhabitants of a city you wish to take by force means that your clan can avoid competition with the remnant of a competing clan. By eliminating the children, they eliminate long-term resentment that can work against them in the future. But it also eliminates the conquereds’ genes. Evolutionary theory shows that what at first might seem to be merely a political policy also has a genetic effect: genes that influence people to kill “enemy” children - if any - will have an advantage over the genes of peaceful people - they will, on average, be slaughtered by the former, not vice-versa.

While evolutionary theory explains this brutality, it also suggests a solution to the problem. Knowing that the natural process of evolution encourages some nasty behaviors in our fellow man is a powerful realization. While very few people condemn competition, virtually everyone believes competition should be fair. It is pretty obvious that in the genetic lotteries, killing helpless children is an unfair tactic - you reap a big genetic reward with little cost and little risk³. Without evolutionary theory, we wouldn’t have this insight - the only thing standing in the way of people killing their neighbor’s babies would be a vague distaste over the noise, or perhaps the mess. There’d be an emotional reluctance, perhaps - but we wouldn’t have any knowledge about why such a thing is wrong.

Evolutionary theory also suggests ways that society can respond to this bloodthirstiness and suppress the killing of children. One potential way to do that is to found a religion in which an all-powerful sky god condemns the killing. Unfortunately, the god of the most popular religion in the United States is depicted as being pro-infanticide⁴. I guess that explains why this idea hasn’t worked out.

Obligatory good art: Giotto’s Massacre of the Innocents.

Another way is to create a government that (1) protects each of the society’s productive members right to exist, and (2) allows them to make effective decisions about when to reproduce. There’s a potential evolutionary advantage to leveling the genetic playing field in this manner. By ostracizing and penalizing child-killers, their genes will be less perpetuated in your society’s gene pool. As a result, your gene pool should be more diverse, rather than dominated by genes influencing infanticide, thus possibly making the species more survivable in the face of changing environmental conditions.

And by giving adults the means to prevent reproduction, the genetic competition is played out in terms of strategy, instead of violence and force. Those who are best at determining when to reproduce, and how many times, prevail in the genetic lotteries. To the extent that genes determine good decision making, this is a recipe for evolving a smarter society.

So much for the beneficial insights of evolutionary theory. Let’s leave aside the peaceful morality that proceeds from evolution, and explore what intelligent design has to say on the issue.

I started with a Google search, and I was disappointed to find that Walker is correct when he says that intelligent design creationism is silent on the issue. I found nothing from an intelligent design creationist on the web⁵ that said anything about intelligent design creationism’s views on infanticide.

That leaves us to explore the issues for ourselves. As Walker notes:

What characteristics of the unknown designer might we infer from infanticide? … [T]he issue here is that ID as a theory is doomed unless something is known about the designer and that information can be used to generate hypotheses about the real world.

That’s a real problem, because intelligent design creationists frequently refuse to say who or what the creator/designer is. But we can obviously go the other direction here. Infanticide is widespread, not only among people, but also in nature. This is observed fact. Given this, what does it say about the designer/creator?

What it necessarily must say is that the designer/creator found nothing wrong with killing children and helpless young animals. Otherwise, this capability would not have been built into creation. Even if we accept the rather ad-hoc and evidence-lacking assertion that “the fall” corrupted creation and infanticide did not exist prior to then, organisms could not be physically capable of infanticide if the tools for it had not been built into life in the first place.

Intelligent design creationists say that biological structures are intelligently designed to fulfill their functions. If so, that means that the biological structures that animals use to kill babies were intelligently designed for the purpose of killing babies.

Furthermore, infanticide is practiced by organisms that are incredibly diverse. Even plants do it. Bacteria do it. Lobsters do it. The list is incredibly long, and as far as I can tell every class of organism does it. That suggests that not only does the designer/creator condone infanticide, but that he’s positively enthusiastic about it.

This picture of the creator/designer is not, I would suggest, the kind of supernatural power or little green alien that my readers would enjoy hanging out with.

Of course, science is all about finding out what is true, and not about gathering support for what you want to be true. So all we need to do is look at the evidence. Evolutionary theory makes several predictions and provides powerful explanations for what we observe in the biological world - including infanticide. It is so successful at this that it it responsible for originating or explaining - or both - all of our knowledge of biology. Every day, more scientific studies about evolution are conducted, and every day, all of them show that evolution is sound.

Meanwhile, intelligent design creationism? It explains nothing. Even infanticide, which it explains, presumably, by hypothesizing a bloodthirsty infanticide-loving designer/creator, is better explained by evolutionary theory. But it goes beyond this. An intelligent design creationism that explains infanticide with a designer/creator that approves of violence against children cannot cope with the simultaneous presence of altruism in organisms - while evolutionary theory does.

Not only does science better explain what we know about infanticide, in a modern civilization evolutionary theory shows us how the problem it represents can be solved. Meanwhile the primary accomplishment of intelligent design creationism has been to demand that the government subsidize the teaching of its nonsense by raising taxes on the populace so stickers can be placed in texbooks and teachers can be forced to offer religious indoctrination in science class.

4. In Joshua 8, god is said to not only have approved of, but to have planned, the killing of the children of Ai. In 1 Samuel 15:3, god commands the slaughter of infants. Psalms 135:8 & 136:10, god is praised for killing babies. Psalms 137:9, god commands babies be dashed against the rocks. Exodus 12:29, god plans and carries out the killing of the oldest child of every family in an entire country. Etc. [↩]
