Ron Numbers gave a brief history of creationism, reminding us that perhaps a majority of the people in the world reject Darwin, and he also emphasized a few facts in that history that many would find surprising.
There was no organized opposition to evolution until the 1920s, when it was marshalled by William Jennings Bryan, who was most concerned about the ethical implications of evolution. He made the point that the popular movie about the Scopes trial, Inherit the Wind, was historically inaccurate. One of the most memorable moments in the movie was when Darrow pinned Bryan down on the date of the creation to 4004 BC…but Bryan had no such preconception. The primary strain of creationism at that time had absolutely no problem with the age of the Earth, and Bryan plainly stated in interviews and speeches that he was a proponent of the day-age theory, in which the “days” of creation week were not required to be 24-hour modern days.
These early creationists had no bone to pick with geology at all, and were unperturbed at the thought that the world was hundreds of millions of years old. The two dominant explanations were the day-age theory, which stretched out the time-span of creation week to cover the whole of geological time, and gap theory, which argued that between the creation of the world mentioned at the beginning of Genesis, and the account of the 6 creation days, there was a long undocumented period of time in which geological history occurred. The latter model was also popular because it was presented in the Scofield Reference Bible, which specifically placed the geological column in a ‘gap’ in the account, and stated that the 6 days referred to the creation of Eden.
The dissenters from this position were a tiny minority, the Seventh Day Adventists, who were regarded as weird by the majority of fundamentalists. The Seventh Day Adventists credited a source of divine information other than the Bible, the prophecies and visions of their founder, Ellen White, who was the source of the idea that Genesis had to be describing a literal six 24-hour day creation occurring 6000 years ago. Her disciple, George MacReady Price, came up with the idea of wedging all of geology into the Noachian Flood. These were not popular ideas.
The mainstreaming of literalist creationism occurred in the 1960s, when John Whitcomb and Henry Morris wrote The Genesis Flood. It’s basically the same nonsense he Seventh Day Adventists were peddling, but Whitcomb and Morris were not SDAs, making it possible for conservative Christians, who regarded Seventh Day Adventism as a freaky cult, to coalesce in the formation of the Creation Research Society. These people had no ambition to convert the research community, but instead wanted to wean bible-believers away from what they considered the compromises of day-age and gap theory.
Another consequence of this shift was that it opened up hard-core creationists to a kind of hyper-evolution: they had to explain how a small ark of fixed size could contain all the animals in the world, so they had to postulate a small number of created “kinds” that diversified into new species after the flood, at a pace evolutionary biologists consider absurd.
In the early 1980s, these new, literal creationists got ambitious and started trying to push into classrooms by legislation, efforts that got stymied by major court decisions in Arkansas and Louisiana, which ruled that mandatory teaching of creationism was unconstitutional. One consequence of the Arkansas decision was that, when the creationists had been anticipating victory, they had begun assembling a creationist textbook. When they lost instead, they had to rewrite to remove the word “creationism” and replace it with “intelligent design”.
Numbers talked a bit about Intelligent Design, and argued that it was different from the previous version of creationism…but not in a good way, or in a milder way. The brainchild of Philip Johnson, Intelligent Design was far more radical than the previous iterations — Johnson opposed methodological materialism, and specifically wants to incorporate god into science. While arguing that ID is something new, though, he also made it clear that it is not because ID is a secular theory — it’s an extraordinarily religious idea, backed by religious proponents, and funded by theocratic extremists like Howard Ahmanson.
He ended by giving us the discouraging news that 65.5% of Americans believe in creationism, and that the movement is expanding beyond US borders to the Islamic and Jewish world, too. Bummer, man. He could have at least offered some hope for the future.
It was a fine evening here in Chicago, with all these superstars of evolutionary biology in attendance. It was also an information-dense evening — I tried to keep up on my little laptop, but I know I missed a lot. Fortunately, I’m not alone: Rob Mitchum and Jeremy Manier were also covering the event, and have a play-by-play available. I’ll just dump what I’ve got here tonight. I do have wi-fi passwords so I can get things up a little more promptly tomorrow and Saturday.
Richard Lewontin opened up with a few deprecatory comments about the religiosity of our surroundings (the talks were given in a chapel) and our purpose, the reverence given to Saint Darwin. He was there to talk about the importance and danger of metaphors, and addressed two of them. The New Testament metaphor of genes make organisms, and the Old Testament metaphor that organisms adapt to the environment.
It’s not true that genes make organisms. Organisms are consequence of interactions between inside and outside, genes and molecules, and the phenotype is not predictable from the genotype. He discussed the classic example of norms of reaction in Achillea, showing growth of clones in different environments. Cloned plants taken from cuttings — so they’re genetically identical — and grown in different environments show different patterns of growth, and, for instance, don’t show a simple relationship between morphology and the elevation at which they’re grown. Another example is bristle number in Drosophila which show similar unpredictable pattern of response to temperature. Another thing to think about: look at the fingerprints on your left and right index fingers. They’re not identical, but they have the same genes and formed in the same environment at the same time. Living organisms are the outcome of developmental and physiological processes influenced four factors: genes, non-genic molecules in the embryo, environment, and random variation.
Biologists have known this for years but have fallen prey to the metaphor of genetic determinism. (He also mentioned another bad metaphor as an aside: the cell as a machine.)
The other bad bad metaphor is the idea that organisms adapt to ecological niches. Organisms do not fit into preexisting niches. You can’t look at “niches” in the environment…there are an infinity of them. The organism determines the niche. A better idea is the concept of niche construction, in which niches change as organisms evolve. Organisms take whats available and integrate it with their biology, and the life activities of organisms determine what is relevant. When did living in water become the niche of the ancestral seal?
Organisms seek out appropriate environments, the idea of microclimate. Put mesic (adapted to environments with a moderate amount of moisture) and xeric (dry or desert) flies in evironments with different zones of humidity, one surprising result is that the xeric flies move most quickly and determinedly to moist areas, more so than mesic flies. It’s not that dry-adapted flies can handle dryness better…it’s that they’re better at finding damp microenvironments.
Lewontin gave several other examples of organisms that respond in sophisticated ways to confound simple interpretations of adaptation: that we all produce shells of altered microenvironments around us by our metabolic activity; that trees can count the number of days of a certain temperature to trigger flowering; that Daphnia measure the rate of environmental change to determine whether to reproduce sexually or asexually; that organisms modulate the statistical properties of their environment by storage.
He suggested that we need to set aside the bad metaphor of adaptation for a less bad metaphor of construction. Unfortunately, this creates a difficult situation for scientists interested in selection, because, for instance, frequency dependent selection means that the addition of new genotypes to the gene pool (which happens constantly) causes fitness to change in unpredictable ways. It’s a game of rock-paper-scissors with a lot more than just three possibilities. He closed by saying that addressing this kind of problem should be the goal of the next generation of evolutionary biologists.
Here’s part of an explanation I’ve liked for a long time: they’re a product of developing cognitive processes that bias the brain to model the world with supernatural shortcuts.

Bill Donohue has put me on his mailing list, so I get these ‘alerts’ from the Catholic League several times a day. Here’s the latest (the colors are as sent to me: I guess it was very important!)
On Thursday, October 29, 2009 at 8:45 am ET, Catholic League President Bill Donohue will appear on Fox News Channel’s “Fox and Friends.”
He will discuss the recent attack on Jesus on HBO’s “Curb Your Enthusiasm.”
“Attack on Jesus”. Jebus, what a loon.
Well, you know what the only reasonable response to such foolishness is. We must watch the Attack on Jesus, and laugh, even if I didn’t think it was that funny.
You know, I still have a stash of holy crackers. I might just have to escalate some more, just to witness Donohue’s public meltdown, and make a point: nobody, especially anyone who is not Catholic, has to revere Catholic icons, and demanding that we do is only gonna get Jesus hurt some more.
I’ll be traveling tomorrow, so I’ll have to miss the execrable Fox and Friends…but I’m sure the swollen and empurpled spitting Donohue will be on youtube when I get back.
It’s rather pathetic when banned loons like “help ma boab” come crawling back, begging to be released from the dungeon…especially when their apologies are this insincere. It just reaffirms why he got tossed in there in the first place.
I’m Sorry
I’m sorry that I trod on someone’s arrogant, over-inflated, preposterous ego. Can I come back onto your blog? I promise I won’t do it again. Pretty please?
No.
I’m liking these CreatureCast videos from Casey Dunn — I showed the first in this series, now here’s the second. It uses very simple animation to illustrate basic concepts…like the evolution of multicellularity in this one.

Every once in a while, this administration gives me a tiny bit of hope. They’ve just come out against the anti-free speech activities of Islamic nations in the UN.
The Obama administration on Monday came out strongly against efforts by Islamic nations to bar the defamation of religions, saying the moves would restrict free speech.
“Some claim that the best way to protect the freedom of religion is to implement so-called anti-defamation policies that would restrict freedom of expression and the freedom of religion,” Secretary of State Hillary Rodham Clinton told reporters. “I strongly disagree.”
It’s a small thing, but good to see. Now they just have to make some long strides forward on a few big things (like, say, a certain war, and health care, and the economy).
Answers in Genesis, that site that tries to promote an alternative view to natural origins, has put up an article to answer that question that I’m sure is pressing on everyone’s mind as we get close to Halloween: Are demons real?. You won’t be surprised to learn that AiG’s answer is that yes, they are.
According to the Bible, demons are real spiritual and personal beings, not just forces or phenomena in the physical and psychological realm. Various Bible passages reveal that they have intellect, emotions, and will. They think, hate, and choose plans of action against God, Christ, and mankind. They especially hate believers in Christ because believers belong to Christ and are foes of Satan.
The Scriptures provide many details about demons. They are spirit beings created by God and responsible to God (Colossians 1:16). They are creatures limited in space, time, and powers. They have become morally perverted and are called “unclean spirits” (Matthew 10:1) or “evil spirits” (Luke 7:21). They promote immoral and sensuous lifestyles (2 Peter 2:1-18). They cause false teachers of depraved minds to oppose the truth and appeal to carnal and selfish impulses (2 Timothy 3:6). They sow false followers of Christ in the world (Matthew 13:37-42). They blind the minds of unbelievers to keep them from seeing God’s salvation through faith in His Son (2 Corinthians 4:3-4).
Wow, they’re everywhere. The best part, though, is the next paragraph.
Demons promote primitive religions, magic, superstition, and worship of evil spirits. They are the dynamic behind idolatry and their devotees, whether worshipers of the gods Marduk, Asher, Zeus, Jupiter, Apollo, Ra, Diana, Aphrodite, or a host of lesser manmade deities.
“Like Jesus,” I ask, innocently?
I will agree that belief in demons is a sign that you’re dealing with a primitive religion and superstition.
