With respect to “A “junk DNA” jumping gene is critical for embryo cell development, philosopher of biology Paul Nelson writes to say, In personal correspondence over the past couple of years with a tenured geneticist at a major university who is a “junk DNA” proponent, I’ve pointed out that “x has no function” propositions in […]
Junk DNA: Darwinism evolves swiftly in real time
| June 20, 2018 | Posted by News under 'Junk DNA', Darwinism, Evolution, Genetics, Intelligent Design |
From David Klinghoffer at ENST, on Darwinism and the recent find that junk DNA can alter genitalia: The “junk” view, once a prized piece of evidence for neo-Darwinian theory, is thus reduced to the province of the benighted, the reactionaries who “still refer to [it] as ‘junk’ DNA,” after science has already passed them by. Having […]
Junk DNA can actually change genitalia
| June 20, 2018 | Posted by News under 'Junk DNA', Biology, Darwinism, Intelligent Design |
From at ScienceDaily: Mammals will develop ovaries and become females unless the early sex organs have enough of a protein called SOX9 at a key stage in their development. SOX9 causes these organs to become testes, which then direct the rest of the embryo to become male. The amount of SOX9 produced is controlled initially […]
At Quanta: Cells need almost all of their genes, even the “junk DNA”
| May 26, 2018 | Posted by News under 'Junk DNA', Intelligent Design |
From Veronique Greenwood at Quanta: By knocking out genes three at a time, scientists have painstakingly deduced the web of genetic interactions that keeps a cell alive. Researchers long ago identified essential genes that yeast cells can’t live without, but new work, which appears today in Science, shows that looking only at those gives a […]
Amazing! A new way “junk DNA” is useful, admitted
| April 11, 2018 | Posted by News under 'Junk DNA', Intelligent Design |
From ScienceDaily: Their findings, published recently in the journal eLife, indicate that this genetic “junk” performs the vital function of ensuring that chromosomes bundle correctly inside the cell’s nucleus, which is necessary for cell survival. And this function appears to be conserved across many species. This pericentromeric satellite DNA consists of a very simple, highly […]
Researcher: Dark DNA raises fundamental questions about evolution
| March 12, 2018 | Posted by News under 'Junk DNA', Evolution |
From Adam Hargreaves at New Scientist, No doubt you have heard of dark matter, which is thought to make up over a quarter of the universe. We know it’s there; we just haven’t been able to detect it. Well, something similar is afoot in the genome. My colleagues and I have dubbed this elusive genetic […]
Junk DNA watch: Alus can have their memory re-programmed on several levels

From Sal Cordova at Creation-Evolution Headlines: Chris Rupe co-authored the book Contested Bones with John Sanford to tell about the inadequate evidence for human evolution. The book is almost entirely about bones and the fossil record, but there are 3 pages in that book that refute claims by evolutionary biologists that the human genome is […]
New hypothesis as to why flowering plants predominate
| January 15, 2018 | Posted by News under 'Junk DNA', Evolution, Genetics, Intelligent Design, Plants |
From ScienceDaily: Scientists have found an explanation for how flowering plants became dominant so rapidly in ecosystems across the world — a problem that Charles Darwin called an ‘abominable mystery’. In a study publishing on January 11 in the open access journal PLOS Biology, Kevin Simonin and Adam Roddy, from San Francisco State University and […]
Thought for the Day: “False sciences” make the method come first
| December 21, 2017 | Posted by News under 'Junk DNA', Intelligent Design, Philosophy, Science |
Philosopher Étienne Gilson (1884–1978): A scientist never begins by defining the method of the science he is about to initiate. Indeed, the surest way of recognizing false sciences is by the fact that they make the method come first. The method, however, should derive from the science, not the science from the method.” – Etienne […]
Viruses hijack “junk” (non-coding) RNA, turns out many non-coding functions “have not been identified”
| December 13, 2017 | Posted by News under 'Junk DNA', Intelligent Design |
From Nicholas S. Heaton & Bryan R. Cullen at Nature: Long non-coding RNAs (non-coding RNAs more than 200 nucleotides long) have roles in many aspects of cell biology4,5.
