A Darwin quote for Darwin Day

For Darwin Day, I thought I'd (re)post one of my favorite Darwin quotes. Here it is:
I cannot persuade myself that a beneficent & omnipotent God would have designedly created the Ichneumonidae with the express intention of their feeding within the living bodies of caterpillars, or that a cat should play with mice. -- From a letter to Asa Gray, 22 May 1860

The Ichneumonidae is a family of wasps. A very big family. It is, in fact, one of the largest families in the largest class of animals, the insects. There are over 60,000 species of ichneumonid wasps, each one, according to creationists, specially designed by God. My question for them is the same as Charles Darwin's: Why? Why would a beneficent and omnipotent God do such a thing?

To understand the question, it is necessary to know a bit about the ichneumonids. First of all, most are parasitoids, which means that their larvae develop inside the body of a living host, which they slowly eat alive. Eventually, when the wasp larvae pupate, they erupt out of the body of the host that they have gradually consumed, tormented, and destroyed as larvae.

It is easy to see how such a thing could exist from an evolutionary standpoint. The body of a caterpillar is good food for larvae. It's not surprising that some organisms have evolved to take advantage of it. But what kind of a God would purposefully design it to be that way?

I have heard five different answers:

  1. God originally made everything good; there was no suffering or death until the fall of Adam. Then all hell broke loose. Animals immediately began to kill and eat each other, and predators, parasites, parasitoids, and pathogens roamed the earth. (Creation Ministries)

  2. God made things nasty right from the start just to show us how important we are to him. He knew that Adam would sin, so he made nature cruel to show us the serious nature of sin. (Dembski's Defective Design Inference)

  3. God made everything good and then Satan messed everything up. (Gregory Boyd's Cosmic Warfare Theodicy)

  4. God likes it just fine the way it is. He created it that way for is own pleasure. He likes to watch things suffer. (David Snoke)

  5. God couldn't help it and had nothing to do with it. He would have liked to create a kind and peaceful world, but he had to let things play out according to the laws of nature, over which he had no control. So the ichneumonid wasps just evolved, along with everything else, over millions of years while God sadly watched from a distance, unable to affect the outcome. (Ken Miller)

For each of these answers, though, I have a question.

  1. How did things change so quickly? Were the 60,000 ichneumonid species specially created by God the moment Adam sinned? Or did God magically turn 60,000 butterfly species into parasitic wasps? Or did they all evolve (super)naturally in a few thousand years?

  2. How do the ichneumonids teach us about sin? Until about the time of Darwin no one (except God) even knew they existed? Yet God created them just for us, just to teach us a lesson?

  3. So Satan created the Ichneumonids? Along with scorpions, spiders, snakes, and sharks? He must have been a busy guy!

  4. How could a kind and loving God create things just to watch them suffer?

  5. A God who can't create or control anything isn't a God at all.

Here are some cool videos about the Ichneumonids.

The first one is from David Attenborough's marvelous "Life in the Undergrowth."

And here's one showing a Ichneumonid wasp (Megarhyssa sp.) drilling through the bark of an oak tree to deposit an egg in the tunnel of the siricid wood wasp, whose larva the Maegarhyssa lava will eat alive from the inside in the traditional Ichneumonid fashion (just like God intended it to be).

Whose face do you see on the moth?

Isn't it great? Jesus has returned again -- this time on the back of a moth in east Texas.

But I'm not so sure that it really is Jesus. I mean, aren't those horns on the top of his head? And what about those long, goat-like ears and beard? It looks more like Jesus' little brother Satan to me.

I may be wrong, but I think the species of moth that God selected for Jesus' (or Satan's) image is Eacles imperialis, the imperial moth. It's common in the southern United States and is known for its variable dorsal markings.

But take a look at this one (from Butterflies and Moths of North America). Who do you see on its back?

Now that is not Jesus, folks. It's either Satan or Muhammad -- without fingerprints they're hard to tell apart. (And what are those pigs doing on each side of his head?)

The Bible and the Quran agree: Insects have four legs

In a previous post, I mentioned that the Bible and the Quran agree on the worth of a woman. A woman is worth about half as much as a man.

Well, here is something else they seem to agree on: insects have four legs.

Here's what the Bible says:

Even these of them ye may eat; the locust after his kind, and the bald locust after his kind, and the beetle after his kind, and the grasshopper after his kind. But all other flying creeping things, which have four feet, shall be an abomination unto you. Leviticus 11:22-23

And here's the Quran:

Allah hath created every animal of water. Of them is (a kind) that goeth upon its belly and (a kind) that goeth upon two legs and (a kind) that goeth upon four. Quran 24:45

It's true that neither holy book comes right out and says that all insects have four legs.

But the Bible says that locusts, beetles, and grasshoppers (which are the ones you are allowed to eat) have four legs, while "all other flying creeping things, which have four feet, shall be an abomination unto you." So that would seem to include insects in God's "four legged, flying, creeping things" taxon.

The Quran is a bit less clear, but it too seems to imply that insects have either zero, two or (more likely) four legs.

Isn't it nice that the Bible and Quran agree on something?
