Science thinkmag says it’s time to reconsider what we mean by the word “gene”

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 […]

Just an accident.

The Y chromosome had been reprieved earlier from its status as a vestige about to disappear, but this is newish.

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 […]

In 2013 Larry wrote On Beating Dead Horses I was reminded of this while reading Salvador Corova’s latest post on Uncommon Descent because he refers to beating dead horses [If not Rupe and Sanford’s presentation (8/6/13), would you believe Wiki? In this case, yes]. I’m not going to make any comments. Read it and weep […]

In 2013 functions were identified for many of these “intrinsically disordered proteins” (IDPs), as they are sometimes called.

Larry actually had some rare kind words for me. He said here Cordova is correct. Thanks for the kind words, Larry! Larry goes on to argue that organisms can tolerate lots of mutations and still reproduce. Yes, I agree, but reproduction is not the real thing in question, it is the existence of designs. I’ve […]

No one talks of life there (unless we introduced extremophiles?).

For a number of years, many of us at UD have made the argument that evolutionary theory, in practice, is of almost no help whatsoever in getting at the secrets of biology. I’ve taken the position personally that it actually hurts, and that it is not a matter of indifference to the study of biology […]

Researchers found non-coding DNA was source for new genes in fruit flies.

Here is a piece over at Phys.Org dealing with “long, intergenic non-coding” RNA. “When we removed the specific lincRNA, we looked at the mouse brain and the progenitors were reduced. As a consequence probably, the population [of neurons] that sits on top of the cerebral cortex are reduced … It’s likely that in the future […]

Is someone keeping track of all this for an Atlas of Junk DNA?
