Ayala and Falk Miss the Signs in the Genome

In his recent response to Stephen Meyer’s Signature in the Cell, Francisco Ayala claimed that repetitive portions of our DNA called “Alu” sequences are “nonsensical.” Ayala wrote: “Would a function ever be found for these one million nearly identical Alu sequences? It seems most unlikely.” In his response to Ayala, Meyer showed that Ayala is factually wrong about this. According to recent technical papers in genomics, Alu sequences perform multiple functions. In a rejoinder to Meyer, Darrel Falk defended Ayala and claimed although “a number of functional regions have been discovered within Alu sequences,” there “is no question that many Alu sequences really have no function.” In my last blog, I showed that the vast majority of the genome is Read More ›

Reading Wesley Smith: Why the Darwin Debate Matters

If the intelligent-design side in the evolution debate doesn’t receive the support you might expect from people who should be allies, that may be because they haven’t grasped why the whole thing matters so urgently. I got an email recently from a journalist whom I’d queried on the subject. “All told, I’m on the ID side of the debate,” he wrote, “but it isn’t a pressing interest for me.” Anyone who similarly doesn’t quite “get it” should read our friend and colleague Wesley J. Smith’s new and important book on the animal-rights movement, A Rat Is a Pig Is a Dog Is a Boy. If you follow conservative journalism, you’ve likely heard about the book from the contentious deliberation it Read More ›

A Response to Questions from a Biology Teacher: How Do We Test Intelligent Design?

A biology educator recently wrote me asking how we test intelligent design using the scientific method, how ID is falsifiable, and how ID explains patterns we observe in nature. These are very common questions that we receive all the time from teachers, students, and interested members of the public, and they’re usually legitimate, sincere, and thoughtful questions. In this case, they certainly appeared to be such, and below I post a slightly modified version of my response to the teacher, withholding any information about the teacher to protect his/her identity: Dear [Snip], Greetings and thanks for your e-mail. ID is most definitely testable and falsifiable. It uses the scientific method and explains many patterns we observe in nature. Let’s start Read More ›

Asking Darrel Falk to Pick a Number, Any Number

I have long questioned the assumption that most genomic DNA sequences are “nonsensical” or “junk.” And given the data that have emerged over the past seven or so years, a functionalist view of genome has robust empirical support. It is for this reason that I think many of the arguments presented by the Biologos Foundation are “wrong on many counts,” to borrow a phrase from Darrel Falk. Here is an example. While reading the “critique” of Steve Meyer’s book, Signature in the Cell, by Francisco Ayala, a number struck me that I know to be incorrect. The integer that I am referring to is “25,000” and it is claimed to be the known tally of genes in our chromosomes: The Read More ›

Is Weather Forecasting A Counterexample To Complex Specified Information?: Jeff Shallit on Signature in the Cell

For over a decade, mathematician Jeffrey Shallit has been an outspoken critic of intelligent design. Recently, in a series of blog posts, he has attacked Stephen Meyer’s book Signature in the Cell (SITC) for what he sees as a variety of shortcomings. Some of Shallit’s criticisms merit careful attention, which we’ll present here in weeks to come. Other criticisms, however, are fluffy confections, failing to achieve even the slightness of what Hume called “mere cavils and sophisms.” Let’s look at one such bonbon of sophistry, Shallit’s claim that weather forecasting represents a devastating counterexample to SITC’s argument that complex specified information is, universally in human experience, produced by a mind or intelligence.
