In the previous post I described the debate among evolutionary biologists over the so-called adaptive hypothesis. Some biologists believe that natural selection has the power to drive evolution in adaptive directions, and that most changes that we observe in organisms are there because they confer some adaptive benefit. Other biologists believe that most of the changes we see in organisms over time are due to neutral, non-adaptive processes. You don’t need to take my word for the existence of this debate. Michael Lynch, an eminent evolutionary biologist, lays out the case against the power of natural selection in a paper called “The Frailty of the Adaptive Hypothesis,” 1 published a few years ago for an evolutionary symposium. In it he Read More ›

Stephen Meyer’s new book, Signature in the Cell, continues to get lots of coverage. Dr. Meyer was recently interviewed for CNS and you can watch a video of the entire interview on the SITC website here. Also, over at Uncommon Descent Robert Deyes is reviewing the book chapter by chapter. When the 19th century chemist Friedrich Wohler synthesized urea in the lab using simple chemistry, he set in motion the ball that would ultimately knock down the then-pervasive ‘Vitalistic’ view of biology. Life’s chemistry, rather than being bound by immaterial ‘vital forces’ could indeed by artificially made. While Charles Darwin offered little insight on how life originated, several key scientists would later jump on Wohler’s ‘Eureka’-style discovery through public proclamations Read More ›

Editor’s Note: Ann Gauger is a senior research scientist at Biologic Institute. Her work uses molecular genetics and genomic engineering to study the origin, organization and operation of metabolic pathways. She received a BS in biology from MIT, and a PhD in developmental biology from the University of Washington, where she studied cell adhesion molecules involved in Drosophila embryogenesis. As a post-doctoral fellow in the Department of Molecular and Cellular Biology at Harvard, she cloned and characterized the Drosophila kinesin light chain.

A long-standing controversy exists among evolutionary biologists that is little known outside of professional journals. This controversy is significant because it deals directly with the question of how evolutionary processes produce functional changes in organisms — whether or not the changes we observe are due to adaptive processes guided by natural selection.

Why such a controversy? In his landmark book On the Origin of Species, Darwin proposed natural selection as a force sufficient to account for the organismal complexity and diversity we see around us today. But Darwin knew nothing about genetics or molecular biology. He knew nothing about how variation among organisms was produced or inherited, or what the limits of variation might be. He knew nothing about population dynamics or how difficult it might be for a slightly advantageous trait to spread throughout a population.

In the many years since Darwin wrote his book, scientists have learned much about these topics, and as a result, they have identified four forces driving evolution, not just the one known to Darwin. The four forces are natural selection, mutation, recombination, and genetic drift, and when taken together they affect evolving populations of organisms in sometimes surprising ways. This has led to the controversy I outlined above concerning the efficacy of natural selection to drive evolution in adaptive directions.

Picture a majestic T. rex receiving the tablets of the Ten Commandments in its undersized forelimbs, or an elegant octopus crucified on an old rugged cross with four crossbars instead of one.

Such images are what Kenneth Miller presumably has in mind with his comforting Darwinist thought that intelligent creatures were guaranteed to pop up even in the course of an evolutionary process of purely unguided, purposeless churning. You see, he tells us, evolution was bound to “converge” (as theorized by Simon Conway Morris) not necessarily on a human being but on — well, as Miller has said, it could have been “a big-brained dinosaur, or… a mollusk with exceptional mental capabilities.” Just for fun, let’s grant the scientific merit of “convergence” — though many Darwinists, in fact, do not. My argument here is not with Miller’s science but with his imagination.

A Roman Catholic and a Brown University biologist, Ken Miller is one of those theistic evolutionists who want other religious believers to feel there’s nothing in Darwin to offend religious sensibilities. He and others (such as Obama’s favorite geneticist, Francis Collins) invite us to imagine God being delighted with such creatures, noble and impressive in their way, as the culmination of the evolutionary process that He chose not to guide. But what if the intelligent creature that resulted from all the purposeless churning, and that was intended to reflect God’s own image, had been something really horrible.

That’s the scenario that an author I enjoy, a committed Darwinist and atheist — H.P. Lovecraft (1890-1937) — allows us to contemplate. In his terrifically imaginative horror stories, most set in a spooky, antiquated New England, the great theme is that humanity is but a tiny, unimportant speck in an unimaginably vast universe that has cast up innumerable varieties of extraterrestrial beings, some of which have colonized our planet. Darwinists love him. If you follow PZ Myers’s blog, you’ll know PZ linked the other day to an “Unholy Bible” — Holy Scriptures tweaked along Lovecraftian lines (Genesis 1:1: “In the beginning Cthulhu created R’lyeh and the earth”).

Many of Lovecraft’s creatures are so repellent that when a human being encounters them, he’s as likely as not to die right there on the spot from the sheer terror. Here’s a description of one, depicted in the form of a little statue at the beginning of “The Call of Cthulhu”:

Advocates of Intelligent Design and others who practice skepticism toward the pomposities of much of modern Darwinism can be forgiven a little amusement when they see their detractors engaged in an internal squabble that highlights the philosophical absurdities of the scientistic rationalism that pervades much of modern Darwinism.

Ever since the publication of Jerry Coyne’s New Republic article, “Seeing and Believing,” the Darwinists have been engaged in a three-way tug of war over the issue of “accommodationism.” The gnawing and snarling has pitted three camps against each other in a contest over the right way to wage the PR war against the Intelligent Design movement for the hearts and minds of the scientifically naive.

The Three Non-Amigos

There are, first, those who, scornful of any public dissembling, declare outright their unapologetic commitment to metaphysical naturalism. Generally speaking, these are the New Atheists, whose online champion for several years has been P. Z. Myers, a professor of biology at the University of Minnesota who is perhaps most famous for his public desecration of the Eucharistic Host, a one-time publicity stunt that only temporarily overshadowed his more regular and customary nastiness toward those who consider his narrow scientific reductionism … well, narrow. Coyne, a University of Chicago scientist, has recently joined Myers at the head of the pack.

On one hand this group has called on scientific organizations like the NCSE to take a neutral position in regard to whether Darwinism is reconcilable. On the other hand, they favor a wider war on religion as the only ultimately victorious Darwinist strategy. These are the crazy uncles of the movement — those who the mainstream Darwinists would rather not let the neighbors see.

CSC Director Stephen C. Meyer recently appeared on Jan Mickelson’s talk show to discuss his new book, Signature in the Cell. Now you can download audio and listen in as Meyer discusses Francis Collins, Carl Sagan, the information embedded in DNA, and how arch-atheist Richard Dawkins anticipated the title of Dr. Meyer’s new book.

In May, pro-Darwin-only education advocates issued a press release lamenting that “25 percent of biology teachers do not know it is unconstitutional to teach creationism.” Then last month the National Center for Science Education (NCSE) publicized its new “Creationism and the Law” web page, which states that “Since 1968…, U.S. courts have consistently held that ‘creationism’ is a particular religious viewpoint and that teaching it in public schools would violate the First Amendment of the Constitution.” While these statements are legally correct, they leave out a crucial point of law that the NCSE may not wish to publicize: “scientific critiques of prevailing scientific theories [may] be taught provided that such curricula are enacted with the clear secular intent of enhancing Read More ›

Discovery Institute senior fellow David Klinghoffer has written an insightful column in The Jerusalem Post on the evidence for design in DNA — and what it means for materialism: DNA are three letters full of paradox. What they represent remains little understood by the public, yet they are on everyone’s tongue. Amid the chatter of popular culture, the truth gets lost that DNA is one of the most powerful clues we have of the existence of a spiritual reality, maybe to the existence of God. An acronym for deoxyribonucleic acid, DNA refers to the form taken by the biological information that directs the production of proteins and other cell components. In 1953, James Watson and Francis Crick famously described its Read More ›

In case you missed your chance to listen live last week, you can now listen to Dr. Stephen C. Meyer’s interview on the nationally syndicated Michael Medved Show here. Meyer and Medved discuss the information revolution and the challenge it presents for Darwinism, as well as the argument for intelligent design from information.
