Inessential does not mean non-functional! Gene guns, transposons, some polyploids, programmed apoptosis, etc.

Strictly speaking gene guns are inessential for living organisms, but does being inessential for life make this tool of genetic engineering non-functional? If there are tools for innovation and exploration, they might not be essential, but does that mean they are non-functional? Of course not! In like manner transposons and some forms of polyploidy might […]

Notice, he chooses ENCODE (“if ENCODE is right, then Evolution is wrong” to rant about). ENCODE = little junk DNA.

There are many “Neutral Theorists” who maintain that there is a lot of “junk-DNA,” among which long, non-coding DNA=lncDNA is some of the “junkiest.” But now consider this from Wikipedia: Nevertheless, despite low conservation of long ncRNAs in general, it should be noted that many long ncRNAs still contain strongly conserved elements. For example, 19% […]

Re the junk DNA guy not doing “politeness” any more when defending his challenged view that most DNA is junk, here is some RNA for him to get started on.

Actually, ENCODE was neither misunderstood nor misreported. Life just wasn’t doing what Darwin’s followers said it was supposed to

If either McClintock or Margulis had been Darwin’s girls, they would have been science heads at an approved high school somewhere. Hip. hip.

3-base periodicity is a well-known non-random feature of the DNA. That is to say, a base will sometimes be repeated 3 nucleotides away. This should happen randomly at a frequency of about 25% if all the bases are equally represented, but I got something that was slightly away from random. 3-base periodicity is a well […]

Stretches of DNA that code for proteins are considered non-random, but what about DNA as a whole? DNA Densely Packed without Knots “‘We’ve long known that on a small scale, DNA is a double helix…But if the double helix didn’t fold further, the genome in each cell would be two meters long. Scientists have not […]

Jean Claude Perez is a self-organizational theorist, he is not a creationist. He has also published papers with an occasional visitor to UD, Andras Pellionisz. If the mathematical/musical patterns Perez has found in DNA are improbable relative to laws of physics and chemistry, then he may have found yet another design feature of DNA, and […]

No one asked Darwin’s followers to insist that most of the human genome is junk. They could come down from the trees any time and no one will even notice maybe.

Can designs be selectively neutral and even deleterious but still functional? Yes. As Allen Orr said: selection can wreck their exquisite engineering just as surely as it built it. An optic nerve with little or no eye is most assuredly not the sort of design one expects on an engineer’s blueprint, but we find it […]

Most molecular evolution is neutral. Done. PZ Myers From wiki: Codon usage bias Codon usage bias refers to differences in the frequency of occurrence of synonymous codons in coding DNA. A codon is a series of three nucleotides (triplets) that encodes a specific amino acid residue in a polypeptide chain or for the termination of […]

Most of biological ID literature is focused on Irreducible Complexity and Specified Complexity (Specified Improbability) and information theory, no free lunch, critique of OOL, the Cambrian explosion, etc, But there is another line of argument that is devastating to the claims of mindless evolution that has been underappreciated partly because it is highly technical, and […]

I wrote here in 2006 that the Designer of life has put steganography (hidden messages in DNA) to help scientists understand DNA. The steganography cannot have emerged via selection or neutral evolution, it is just there, it is a design feature. We typically call them “conserved” sequences, but I’ve argued that “conserved” is the wrong […]
