Forces of "Nature" limit dissemination of information

Force of nature gave life its asymmetry Excerpt: “In 2011, Meierhenrich and colleages showed4 that such light could transfer its handedness to amino acids. But even demonstrating how a common physical phenomenon would have favoured left-handed amino acids over right-handed ones would not tell us that this was how life evolved, adds Laurence Barron, a chemist at the University of Glasgow, UK. “There are no clinchers. We may never know.” My comment:I think the clincher is the creation of the…

Physics denied; pseudoscientific nonsense accepted

  The events depicted are now portrayed in the context of Genome Dynamics Events, which are biophysically-constrained RNA-mediated events. RNA-mediated events lead to amino acid substitutions that differentiate the cell types of species. For example: “…the so-called alpha chains of hemoglobin have identical sequences of amino acids in man and the chimpanzee, but they differ in a single amino acid (out of 141) in the gorilla.” Dobzhansky (1973) See also: God, Darwin and My College Biology Class By DAVID P.…

Seemingly futile cycles are not thermodynamically futile

Scientists discover an on/off switch for aging cells The switch controls the growth of telomeres, the timekeepers of cells September 19, 2014 Excerpt: Understanding how this “off” switch can be manipulated–thereby slowing down the telomere shortening process–could lead to treatments for diseases of aging (for example, regenerating vital organs later in life).” My comment: Seemingly futile thermodynamic cycles of protein biosynthesis and  degradation appear to be confusing. I’m somewhat certain that the folks at Salk realize that cycles of biophysically-constrained…

Quantum physics meets Evolutionary Psychology News

Capturing the motion of a single molecule in real time as it oscillates from one quantum state to another September 18, 2014 Excerpt: “It also moves researchers a step closer to viewing the molecular world in action — being able to see the making and breaking of bonds, which control biological processes such as enzymatic reactions and cellular dynamics.” My comment: The making and breaking of bonds controls all biological processes. Luca Turin tried to do move researchers a step closer…

RNA-mediated species diversification from microbes to primates

Mycobacteriophage-drived diversification of Mycobacterium abscessus Biology Direct (15 September 2014) OPEN ACCESS Excerpt (with my emphasis): “Widespread occurrence of phage sequences in almost all studied M. abscessus complex isolates suggests that the rate of prophage invasion is faster than the rate of mutation, implying rapid evolution of M. abscessus.” My comment: The faster rate of prophase invasion suggests ecological adaptations occur more rapidly than evolution. That may be why no experimental evidence of biologically-based cause and effect suggests that evolution…

Biophysically constrained beginnings of RNA and DNA

Any anonymous participant in the discussion of: DNA may have had humble beginnings as nutrient carrier (Sep 01, 2014 by Adam Hadhazy) asks: “when are you going to keep quiet?” In a series of responses, I have explained the problem I have with honoring his request. The following excerpts from Wikipedia and other sources are loosely strung together because there is no point to providing more extensive details of biologically-based cause and effect until others accept the fact that mutations…

Order and disorder: Ecological adaptations not mutations

In the context of order and disorder that includes what is known about quantum physics and light-induced amino acid substitutions in plants and animals, as well as the control of the functional rearrangement of influenza hemagglutinin, I’m beginning to see even more confusion/obfuscation enter the picture of biophysically-constrained ecological adaptations. The nutrient-dependent ecological adaptations are now being put into the context of mutation-initiated natural selection and the evolution of biodiversity (i.e., “Evolution for Dummies”). ECOLOGICAL ADAPTATIONS (not mutations) Nutrient-dependent changes in…

Your comment is awaiting moderation

After I posted 5 of the 14 comments to the National Geographic site during discussion of Mercenary Ants Protect Farmers With Chemical Weapons by Ed Yong, I got the message: “Your comment is awaiting “moderation” Typically, that means I will not be allowed to continue participation in the discussion I started, which is why I am blog-posting my comment here. Perhaps I have been too harsh in my responses to people who keep politely telling me I am WRONG. Perhaps,…

  • What Darwin proved: there’s no such thing as a species
    GENETICS As Animals Mingle, a Baffling Genetic Barrier A short stretch of DNA is challenging what it means to be a species. By: Emily Singer August 5, 2014 Excerpt: “Scientists have dubbed such regions of the genome “islands of speciation.” The persistence of such islands is a phenomenon that has been observed in a variety of […]
