In this week’s Nature, an analysis of the human genome has shown tracing 4,692 homologous recombinations backwards in time leads to “24 distinct groups”. They say their work supports a “‘punctuated’ model of evolution.” I don’t have access to the entire article (maybe somebody does), but the language contained in the abstract is the kind that we might associate with “front-loading”; viz., “Our analysis reveals that human segmental duplications are frequently organized around ‘core’ duplicons, which are enriched for transcripts and, in some cases, encode primate-specific genes undergoing positive selection.”

I did a Wikipedia search for “duplicon” and found nothing; but a Google search gives the following article: Abstract Only. Duplicons appear to be something that is seen at the chromosomal level, and involves low-level repeats of the chromosome. The description this week’s Nature authors give of a duplicon “enriched for transcripts” seems to strongly suggest that the rearrangements that have taken place in the “duplicon” have resulted in more of the genome being expressed. The image I have of what might be taking place comes from my very ancient familiarity with computer programming, and, assuming programming essentials haven’t changed much, it is this: in a computer program there are decision nodes and “go to” nodes that redirect the program to various subroutines, these subroutines being present at some numbered location along the length of the program. If for some reason one subroutine in the program were substituted for another, the program would probably still run, but the output would certainly be different. And, if additional “go to” nodes were “copied”, more subroutines would be expressed. Likewise, if you have genetic instructions along the string of nucleotides that redirects the genetic program to some other downstream part of the genome that allows some particular protein/regulatory function to take place, then, through recombination, different “subroutines” might be inserted, or more signals for transcription might be included.

Maybe this is straining the programming analogy, I don’t know. But in any event, what the authors are reporting doesn’t sound to me like information is being generated (gradualism), but that already present information is being more robustly used (punctuated model of evolution).

Any thoughts?

I just received this by email. Check out the link given. Some time back, David Anderson provided UD with high-quality amusement here. Dear friend, I’m contacting you with this because you’ve given me some previous encouragement, posted a link, or been in contact in some other way in the debate over Darwinism, creation, intelligent design, etc. Many of you will know me as the author of “Does Richard Dawkins exist?” I have just put online a major new audio-visual presentation: “Is belief in divine creation rational? (responding to atheist claims).” The talk is 77 minutes long, accompanied by slides (combined courtesy of Google video), and goes over quite a wide field – rationality, morality, laws (or not?) of logic, Richard Read More ›

ToTheSource.org Exclusive Flew Interview Benjamin Wiker: You say in There is a God, that “it may well be that no one is as surprised as I am that my exploration of the Divine has after all these years turned from denial…to discovery.” . . . But wasn’t there a point in the “argument” where you found yourself suddenly surprised by the realization that “There is a God” after all? . . . Anthony (sic.) Flew: There were two factors in particular that were decisive. One was my growing empathy with the insight of Einstein and other noted scientists that there had to be an Intelligence behind the integrated complexity of the physical Universe. The second was my own insight that Read More ›

The concept of IC is that an IC system has no *functioning* precursors with the same function. Zachriel’s program (and other similar programs randomly generating phrases) don’t challenge IC because the target phrases do not have functioning precursors. As in, they do have precursors but they do not provide the same meaning. Thus, if IC was taken into account normally these words would not promote survivability. If Darwinists would deal with programs instead of phrases they would understand quickly what a functioning precursor is.

Here is a modification of the Phrasenation program that I’d find interesting and possibly even relevant to discussions of ID. I’d like suggestions on how to more accurately reflect the problem Darwinists face.

In a post a couple of days ago I asked the class to discuss a little computer program designed to “illustrate” natural selection.  Of course, the class jumped all over it and easily demonstrated how ludicrous the program’s assumptions were.  That day I got the following emai:

First, let me agree that the simulation does [not?] make a good case for RM&NS, but that is because the simulation itself is poor.  One of your more astute commentators makes the comment that intermediaries should themselves be words, to be ‘viable as life’.  This can be done. Zachriel . . . has a very good simulation that will do that. http://www.zachriel.com/mutagenation/

I am just a humble lawyer, so evaluating Mr. X’s claim that this simulation really is as “golly gee whiz right on the money” as claimed is beyond my ken.  So I asked Gil Dodgen, UD’s resident programing expert, to review the program and give me his take.  His kind reply is below. Read More ›
