What should a good Christian "origins" science program cover?

I originally published the following post in my personal blog. I am now (in 2016) republishing here those articles from my blog that have to do with the focused subject matter of biblical questions and faith. --JAH

Considering the discussion over the last few days, I thought I would attempt a first-draft summary statement of what I think a really quality Christian science program would cover when it comes to origins.

My view: A top-quality science curriculum should discuss the various views and talk not only about the arguments in favor of each view, but about their problems . . . i.e., why advocates of each view are in favor of the view, and why opponents find fault with them. –It can be exceptionally difficult to present all of these positions fairly, but, I believe, fairness is necessary.

Okay. So what views should one cover?

Some typical viewpoints I have seen discussed include these:
  • non-theistic evolution
     
  • theistic evolution
     
  • young-earth creationism
     
  • old-earth creationism.
Some may also throw in a discussion of Intelligent Design.

I think such a list is good . . . as far as it goes.

The problem I find--and I am thankful to Ken Ham and friends at Answers in Genesis for opening my eyes to this matter 14 years ago . . . --The problem I find is how such a list tends to cut out any discussion of the biblical evidence. And it is the Bible that leads in AiG's/Ken Ham's young-earth creationist argument. And, in my mind--again in agreement with Ham and AiG--any curriculum that claims to be Christian needs a discussion of biblical evidence to play a central role . . . at least to the extent that the Bible has evidence to bring to the table.

As a result, I believe a discussion of origins requires quite a bit more nuance than the four (or, possibly, five) options mentioned above.

And so I would like to propose the following divisions for discussion/presentation in a thorough Christian "origins" program:
  • Theism or naturalism? --Clearly, Christians will opt for theism. But the topic of biblical theism v. naturalism and, perhaps, pantheism, needs to be discussed. I imagine this is the place you might want to address the Intelligent Design school of argumentation, though I don't see its success as essential to a theistic worldview, nor its failure as a death knell for such a worldview.
Assuming a biblical theistic viewpoint, then, I believe we need to discuss the following matters:
  • Biblical concordism or non-concordism? Some questions to address: How should we read Genesis 1-3 (let alone 4-11)?
    • Should we look for concord [agreement/peace] between what we read in Genesis 1 and 2 (at least) and how a scientist might describe the beginnings of the cosmos, the biosphere and humankind? [I.e.: Even though the language of the Bible, obviously, isn't going to be scientifically precise in any modern sense of the term, do the biblical descriptions of the beginning of the world and humankind generally match what modern scientists would say? Or, put another way: If we look at the “testimony” of science, should we expect to find that it corroborates what we read in Genesis 1 and 2? (If our answer is YES, then we are concordists. Examples of concordist positions: young-earth creationism; progressive creationism (Hugh Ross); gap theory; day-age theory; etc.)]
    —OR—
    • Should we abandon any attempt to find concord between science and Genesis 1 and 2 and, instead, look solely to science for clues with respect to how and when God created? [I.e.: Even though, based on numerous Scriptural references, we should recognize that God created the cosmos and everything in it, should we read the text of Genesis 1 and 2 as something other than literal history and, therefore, not expect or even attempt to show some kind of correlation to what scientists would have to say and what we read in Genesis 1 and 2? –If our answer to this question is YES, then we are non-concordists. Examples of non-concordist positions: John Walton’s “cosmic temple” interpretation; Johnny Miller and John Soden’s “apologetic against Egyptian mythology” interpretation; etc.)]
     
  • Old-earth (i.e., billions of years) or young-earth (i.e., 6,000 to possibly 10,000 or maybe even 12,000 years old)? Questions to ask: What are we to believe about how old the earth is? What evidence do we find for how old the earth is?

    NOTE: For presuppositionalist young-earthers like Ken Ham of Answers in Genesis, the Bible itself provides much or virtually all of the evidence . . . all of the evidence that really matters. As Tas Walker of AiG expressed it to me back in 1999: “Since we believe the Bible is the Word of God, we start with the Bible. . . . The Bible clearly teaches that the world is young. . . . So, now that we have established that the world is young (~6000 years), we are ready to come to the [scientific] evidence.”

    I mention this because, once more, if someone is going to argue against a presuppositionalist young-earth viewpoint, he or she must present strong evidence for why he or she believes the Bible does not teach a young (approximately 6,000-year-old) earth history . . . and/or, even more difficult, convince these evangelicals why the standard formulas of evangelical beliefs about the Bible should be abandoned or reformulated.
    (When I say what I just said, I am referring to such documents as The Chicago Statement on Biblical Hermeneutics which, in Part 2 of Article XIII, declares, “We deny that generic categories which negate historicity may rightly by imposed on Biblical narratives which present themselves as factual.” That certainly sounds good, but how do we know whether a biblical narrative is presenting itself as factual? --The Statement doesn't address the problem. Though The Chicago Statement on Biblical Inerrancy does state,
    ARTICLE XXII
    We affirm
     that Genesis 1-11 is factual, as is the rest of the book.
    We deny that the teachings of Genesis 1-11 are mythical and that scientific hypotheses about earth history or the origin of humanity may be invoked to overthrow what Scripture teaches about creation.
    And the grounds for affirming the full factuality of Genesis 1-11? . . . --I'm sorry. I'm not trying to get into the details of what a solid Christian course in "origins" will cover. But I am trying to tease out at least a few of the ugly/niggly details that such a course--and/or the advocates of certain positions--will need to address.

    My point here was "simply" to show that those who want to argue against a young-earth presuppositionalist view are going to have to address issues related to well-accepted evangelical statements of faith and not only the scientific evidence.)
  • What mechanism did God use to create the earth and all that is within it: Unmediated (“word spoken --[yields]-- thing created”) or Mediated (“word spoken --[creates/establishes]-- PROCESS (some type of evolution?) --[which yields]-- thing created”)? To what kind of evidence can we point for our views?
Once we tease out these four primary questions, we find the following options:

AtheisticTheistic
EvolutionMediated Creation
(i.e., in the current scientific environment,
Evolutionary Creation)
Unmediated Creation

And then, as best as I can understand, these are the theistic options:

Relationship of Scripture and Science
ConcordistNon-Concordist
Age of EarthOld-EarthProgressive Creation (à la Hugh Ross)
-OR-
Mediated (Evolutionary) Creation
(includes Day-Age, Gap, and other
such theories)
Mediated (Evolutionary) Creation
-OR-
(at least hypothetically)
Unmediated Creation
[I am unaware of any unmediated
non-concordist creationists]
Young-EarthUnmediated Creation
(à la Ken Ham)
[Scientific data w/o
concordist interpretation generally
leads away from Young-Earth view]


If you have any additional suggestions, recommendations, criticisms, or other contributions to make, I would be most grateful for your input!

Wonder at beauty . . .

My brother's co-worker Cecilia recently (two weeks ago) received the truly awesome gift of a new pancreas and kidney. Her recovery has been astonishingly smooth--far beyond expectation. And she is, as she says, "flying high" for the last few days . . . which led her to send a letter of thanks (to those who prayed for her) and praise (to God).

"Please, accept this video song as a little something from me to you," she wrote. "Take a moment to listen and perhaps you’ll get a glimpse of what all I experienced." And she included a link to the following video as presented on Andie's Isle. (Andie's version includes Brian Doerksen's lyrics shown line by line at the bottom of the video frame.)

Meteorology--Another look

Yesterday morning, as I normally do, I joined a few men at our church for a weekly prayer time. And we prayed about the recent spate of violent wind storms on the eastern seaboard of the United States. We prayed for the victims. We prayed for our country. We also prayed--actually, I led in this prayer--that if this is God's judgment upon us for any of our country's numerous sins, from our prideful pursuit of financial and material wealth at all costs, including the poisoning of our environment, to our willfulness and ignorance of [as in, willfully ignoring] God, to . . . well, any of dozens of sins that could be chalked up against us . . . we prayed for God's mercy.

And even if these are not God's judgments upon us, still: we prayed for mercy.

As we prayed these things, I got thinking of what I wrote a few days ago about meteorology. I wrote at that time:
When the Bible speaks of the storehouses for rain and snow and wind and the windows of heaven and so forth (Genesis 7:11; 8:2; Job 38:22; etc.) . . . and when it tells us how God controls these storehouses and windows (Job 38:22; Jeremiah 10:13; and so forth), is it not touching on matters pertaining to nature (as well as, on occasion, history)? And assuming this is the case, then when meteorologists speak of high- and low-pressure systems and evaporation and transpiration and sublimation and precipitation, are they not attempting to "disprove the teaching of Scripture or (to have their extrabiblical views) hold priority over" Scripture? If someone wants to say that this is surely not the case, then I would like that person to explain, on Scriptural grounds alone, how and why he or she is right and I am wrong!
And as I thought once more about what I had written, I got thinking that I should come back and say a bit more about this matter of meteorology and science and Scripture.

"Weird" Science #3: Symbiosis, Part 1

This post originally appeared on my personal blog. Ported to Forbidden Questions on 11/21/2011.

I'm writing this as if it is its own separate subject, even though, in my mind, it's not. (It's closely related to what I began to touch on in my preceding post about Soil.)

My friend Perry Marshall encouraged me to read some books by Lynn Margulis, former wife of Carl Sagan. He mentioned her books in his article The New Atheism, Genesis 2 & Symbiogenesis. What he said there intrigued me. But then I wrote to him and he made some stronger recommendations. So I picked up a number of Margulis' books and was promptly impressed.

EXCURSUS

If you have any training in modern biology, you will, I'm sure, find me hopelessly behind the times. But I might as well reveal my inadequate training--or, perhaps, my failure as a student in high school.

Until I had begun looking at Margulis' Kingdoms & Domains, I was still working largely under a two-kingdom model of biology: there are plants and there are animals. Of course I knew there were bacteria and other microbes. But I don't think I ever placed them into a hierarchy of biological kingdoms. I think I considered them as a kind of cross between or not fully within either the plant or animal kingdom.

So it came as quite a shock when I discovered there are at least five biological kingdoms now recognized in the profession: prokaryotic (non-nucleated) Bacteria, eukaryotic (nucleated--i.e., having a nucleus) Protoctista (unicellular microorganisms), and the three eukaryotic multicellular kingdoms of Plants, Animals, and Fungi.

And then, upon a little further study, I found that even Margulis' taxonomy is . . . well . . . a little parochial. I found that many biologists actually prefer to speak of six kingdoms: the prokaryotic Bacteria (now identified as Eubacteria), and the eukaryotic Protoctista (or Protists), Plantae, Animalia and Fungi--as Margulis acknowledges, plus another kingdom of prokaryotes (non-nucleated organisms), the Archae or Archaebacteria, which are distinguished from the Eubacteria primarily by genetic differences.

As Wikipedia says,
Based on such RNA studies, Carl Woese divided the prokaryotes (Kingdom Monera) into two groups, called Eubacteria and Archaebacteria, stressing that there was as much genetic difference between these two groups as between either of them and all eukaryotes. Eukaryote groups, such as plants, fungi and animals may look different, but are more similar to each other in their genetic makeup at the molecular level than they are to either the Eubacteria or Archaebacteria.
Well, it turns out there are other ways of dividing the kingdoms. The Wikipedia article actually concludes with a kind of throw-up-your-hands-in-despair gesture when it says, "[R]esearch in the 21st century does not support the classification of the eukaryotes into any of these systems."

But back to my notes about Margulis.
Margulis' prime thesis in Microcosmos, Symbiotic Planet, and Acquiring Genomes, is that random mutation is a minor contributor at best to genomic drift (and, therefore, evolutionary change-through-time). Far more significant, she urges, is the acquisition and integration of genomic information through symbiotic merger of organisms, . . . most especially at the level of bacteria.

Indeed, she suggests that the nuclear contents of all eukaryotes come from bacteria: the chloroplasts from cyanobacteria and the mitochondria from oxygen-respiring proteobacteria. The basic cell itself, she suggests, comes from a merger of motile eubacteria and protein-synthesizing archaebacteria.

Perry Marshall provides a simple, graphically-engaging presentation of the basic ideas on his Cosmic Fingerprints website.

But he does more than that. A lot more. He proposes that
over the last 3.5 billion years . . . [DNA] has efficiently adapted and evolved from a single cell to occupy every ecological niche imaginable.

From the frozen ice sheets of the Antarctic to the punishing heat of the Sahara. From the ants under your kitchen sink to glorious singing birds in the Amazon rain forest.
Moreover,
This did not happen through accidental random mutation, . . . [but] through an ingenious algorithm that engineers its own beneficial mutations.
In essence, he says, God engineered into DNA (and all the carriers of genetic information--i.e., viruses, bacteria, and all the eukaryotic organelles that bear genetic information) . . . --God engineered these things to work together (through symbiosis) and intermingle (symbiogenesis) and self-adapt and "upgrade" to survive and thrive in virtually all future circumstances.

I encourage you to read Perry's paper. It's quite easy to read and rather inspiring, actually! Even if you're a committed anti-evolutionist. I hope you'll engage in the thought-experiment Perry suggests.

But what I have just written about: That, too, was not really where I wanted to go with this post.

But I think it's as far as I'm going to get.

So next time I'll try to bring Weird Science #2 (Soil, Part 1) together with Weird Science #3 (Symbiosis, Part 1) to generate . . . well . . . you'll see.

Maybe I'll call it Soil Symbiosis. Or something like that.

Self-healing DNA . . .

This post originally appeared on my personal blog. Ported to Forbidden Questions on 11/21/2011.

My friend Perry Marshall just sent me a link to his latest article titled The Mathematics of DNA.

I have to confess, I can't follow all the math. (Or, perhaps more accurately: I have been unwilling to invest the time to figure out exactly what he is saying when he speaks about the implications of certain ratios.)

But ignore the more technical aspects and--as long as he isn't blowing smoke--the article is filled with some very intriguing ideas, indeed!

I'll quote the introduction just to whet your appetite:
Imagine that someone gives you a mystery novel with an entire page ripped out.

And let’s suppose someone else comes up with a computer program that reconstructs the missing page, by assembling sentences and paragraphs lifted from other places in the book.

Imagine that this computer program does such a beautiful job that most people can’t tell the page was ever missing.

DNA does that.

In the 1940’s, the eminent scientist Barbara McClintock damaged parts of the DNA in corn maize. To her amazement, the plants could reconstruct the damaged section. They did so by copying other parts of the DNA strand, then pasting them into the damaged area. . . .

How does a tiny cell possibly know how to do that???

A French HIV researcher and computer scientist has now found part of the answer.
Check out The Mathematics of DNA.

And if you can find anything wrong with what Perry has written, you may be sure he (and I!) would appreciate hearing about it.

Mutualism

This was originally posted 19 January 2008 on my personal blog. I reposted it here on Forbidden Questions on 25 July 2011.

I watched a video series a couple of months ago called Incredible Creatures that Defy Evolution. Truly astonishing examples of creatures which defy evolutionary explanation . . . either on their own--in the manner their bodies are constructed (the woodpecker whose tongue goes over its skull before re-entering the mouth), or in combination with symbiotic companions (the mussel that requires a certain species of fish to incubate its eggs).

Well, I just bumped into a recent story about another symbiotic relationship that "just" doesn't seem to speak well for evolution as the source of all varieties of life on earth. Check out Ants and Trees Rub Each Others' Backs by Randolph E. Schmid.

More on Eliminating the Concept of Purpose in Science

This was originally posted 6 January 2004 on my personal blog. I reposted it here on Forbidden Questions on 22 July 2011.

I mentioned Jacques Barzun's comments about the historical movement that eliminated the concept of purpose in scientific inquiry. Today I was reminded of some more historical data that contributed to the elimination of this concept.

In an audio summary of a recent business book, It’s Alive: The Coming Convergence of Information, Biology, and Business by Christopher Meyer and Stan Davis, I was startled to hear the following three sentences:
Adam Smith wrote that people follow their own self-interest, which leads to the greatest good for all. Charles Darwin's rule says that species adapt or die. That's the meaning of the term "selective pressure."
I was startled by the obvious juxtaposition of Smith's and Darwin's ideas. But the two ideas mesh perfectly. Isn't Smith's concept of the "'invisible hand' of the marketplace" (in which large-scale public good is the inescapable, unintentional, and wholly unconscious by-product of laissez-faire capitalism) . . . --Isn't that "merely," in the social and economic sphere, what Darwin's concept of "natural selection" is in the scientific/biological sphere?

Now that I think of it, weren't the "social Darwinians" in essence turning Darwin's ideas back to their intellectual and historical predecessor: Adam Smith?

Again: this should have been so obvious. I have considered these ideas before in various ways.
  • Gary North, in Crossed Fingers: How the Liberals Captured the Presbyterian Church (Tyler, TX: Institute for Christian Economics, 1996) points out that William Jennings Bryan's objections to the teaching of evolution in public schools was motivated not by scientific concerns, per se, but by social concerns:
    [While, on the positive side, Bryan argued that democracy gave taxpayers the right to control how their funds should be used, he argued] that a ruthless hostility to charity was the dark side of Darwinism. Had Darwin’s theory been irrelevant, he said, it would have been harmless. “This hypothesis, however, . . . teaches that Christianity impairs the race physically. That was the first implication at which I revolted [when I read Darwin’s work]. It led me to review the doctrine and reject it entirely” (from William Jennings Bryan, In His Image (New York: Fleming H. Revell Company, 1922), 107). [Bryan] cited the notorious (and morally inescapable) passage in Darwin’s Descent of Man: “With savages, the weak in body or mind are soon eliminated; and those that survive commonly exhibit a vigorous state of health. We civilized men, on the other hand, do our utmost to check the process of elimination; we build asylums for the imbecile, the maimed, and the sick; we institute poor-laws; and our medical men exert their utmost skill to save the life of every one to the last moment. There is reason to believe that vaccination has preserved thousands, who from a weak constitution would formerly have succumbed to small-pox. Thus the weak members of civilised societies propagate their kind. No one who has attended to the breeding of domestic animals will doubt that this must be highly injurious to the race of man” (Ibid., 107-108). [Bryan] could have continued to quote from the passage until the end of the paragraph: “It is surprising how soon a want of care, or care wrongly directed, leads to the degeneration of a domestic race; but excepting in the case of man himself, hardly any one is so ignorant as to allow his worst animals to breed” (Charles Darwin, The Descent of Man (New York: Modern Library, [1871], 501). . . .

    Darwin in the next paragraph wrote that sympathy, “the noblest part of our nature,” leads men to do these racially debilitating things (Ibid., 502). Bryan replied: “Can that doctrine be accepted as scientific when its author admits that we cannot apply it ‘without deterioration in the noblest part of our nature’? On the contrary, civilization is measured by the moral revolt against the cruel doctrine developed by Darwin” (Bryan, op. cit., 109).

    Darwin was taken very seriously by many Progressives on the matter of charity. In her book, The Pivot of Civilization (1922), Margaret Sanger [founder of Planned Parenthood] criticized the inherent cruelty of charity. She insisted that organized efforts to help the poor are the “surest sign that our civilization has bred, is breeding, and is perpetuating constantly increasing numbers of defectives, delinquents, and dependents” (Sanger, op. cit., 108). Such charity must be stopped, she insisted. . . . “If we must have welfare, give it to the rich, not the poor,” she concluded (Ibid., 96). “More children from the fit, less from the unfit: that is the chief issue of birth control” (Sanger, "Birth Control," Birth Control Review (May 1919).

    --From North, op. cit., pp. 453-455.

  •  
  • David M. Levy in his fascinating How the Dismal Science Got Its Name (Ann Arbor: The University of Michigan Press, 2002) notes, too, how modern economic theory (i.e., economics post-Smith) interfaced with was borne along by--and bore with it--a social Darwinian view.
I don't know where I want to go from here. Primarily I wanted to make the observation that Smithian economics goes hand-in-hand, intellectually and historically, with evolutionary thought, both biological and social.

I guess I would like to make one more observation, this one coming, too, from the audio tape that inspired my comments here.

I am impressed with how theories of purposeless, "self-organization" (such as Smith's and Darwin's) are being turned to practical ends.

In the audio summary of Meyer's and Davis's It's Alive, I heard the story of a John Deere factory that makes seed planters.
The company uses a computer to create a few random schedules that express the sequence of planters to be built in a digital code made of zeros and ones. That code is a set of instructions, just as DNA carries a set of instructions as "genetic code."

This is possible because of a genetic algorithm. A genetic algorithm is a computer program that simulates the same sort of breeding and evolution that appears to take place in nature. The program can test millions of examples of a production schedule using a simulator. It identifies the schedules that work the best, kills the rest, and then mixes parts of the winning schedules to create new ones. In essence, it breeds new schedules. Then the new ones are tested, and so on. Forty thousand new schedules are tested every night, and the winner is the schedule that runs tomorrow's real-life production on the John Deere factory floor. . . .

In using genetic algorithms to set its factory schedule, John Deere applied two evolutionary concepts. One was the idea of recombination, which is known as breeding in the animal world. The other was to exert selective pressure. . . .

In the John Deere example, a schedule that speeds things up is rewarded by allowing it to breed with other fast schedules. A schedule that is slow dies off without breeding.

The cycle repeats through successive generations, and the agents undergo changes and evolve — in this case, getting faster. In life, the change of one species depends on the change of others. Fast foxes help breed faster rabbits. This is often called co-evolution.

Naturalism and the Scientific Enterprise

This was originally posted 26 December 2003 on my personal blog. I reposted it here on Forbidden Questions on 7 June 2011.

I bumped into the following on the website of the Intelligent Design Network.

As the authors explain:
On October 18, 2002, the Board of Directors of the American Association for the Advancement of Science (AAAS) adopted a resolution which seeks to encourage public schools to ban "the teaching of 'intelligent design theory' as a part of the science curricula." This effectively promotes an "Evolution Only" science curriculum. Evolution Only is also promoted by censoring not only ID [Intelligent Design] but also core criticisms of evolution.
