The Exosome: RNA Degradation and Evolution

When the cell makes a copy of a segment of DNA the result is called RNA. This long, thin molecule has many roles, including transmitting information, regulating the cell’s activities and helping molecular machines perform various tasks. But when its job is done, an RNA molecule must be broken apart. The job of destroying RNA is crucial for without it the cell’s RNA would rapidly build up and kill the cell. So cells are equipped with an intricate machine that chops up RNA molecules when they no longer are needed. This RNA degradation machine is called the exosome and it is comprised of ten finely-tuned proteins, nine of which form a cylinder through which the spent RNA is threaded. The Read More ›

Plant Growth and Evolution

You probably never wondered how plants know which direction to grow. In the soil the roots grow downward and above ground the plant grows upward. This vertical motion seems as natural as Aristotle’s physics. Doesn’t it just happen? But as one researcherexplained, …  Read more

Tonight’s Feature Presentation: Epigenetics, The Next Evolutionary Cliff

We’ve discussed epigenetics, those incredible genetic regulation mechanisms such as molecular barcodes stamped onto DNA,histones, those incredible DNA packaging proteins that also have their own barcodes, the different kinds of barcodes, and how these marvels have falsified so many evolutionary predictions. If it all went by too fast then maybe tonight’s Feature Presentation will help tell a thousand words. You may need to view it a few times to follow the details, but the underlying plot should be clear.  Read more

Evolutionist: “Evolutionary Processes Not Fully Understood”

Frauke Gräter’s latest paper on how the speed of protein folding evolved begins by stating that the disparity in protein folding times (from microseconds to hours) is the result of roughly 3.8 billion years of evolution during which new protein structures were created and optimized. No citation is given because no citation is available. As usual, evolutionists begin their work with non scientific premises. As if sensing a problem the paper next offers a partial concession: “The evolutionary processes driving the discovery and optimization of protein topologies is complex and remains to be fully understood.” In fact …  Read more

What Really Matters

I believe there are big problems with evolution. But I could be wrong. Or perhaps I’m right but some form of evolution is nonetheless true. Evolutionists, on the other hand, are much more certain and there is a never-ending drum roll of high truth claims from their camp. These truth claims are unwarranted and it is them, rather than the theory itself, that are the problem. So I’m not so much concerned about the theory itself as I am about the certainty with which it is presented.  Read more

Evolution is Getting Slammed Again in This Transcription Factor Research

New research on how certain transcription factors work together is causing major problems for the theory of evolution. Transcription factors are proteins that attach to DNA and turn genes on or off. These regulatory proteins have recently been promoted to star status by evolutionists because their expectation that evolution proceeds by creating new proteins has fallen short. Instead of creating new proteins, our modern-day Epicureanism is now supposed to have reprogrammed how existing proteins are used in a mind boggling circuitry of molecular regulators, of which transcription factors play a major role. As one evolutionist explained:  Read more

RetroVirus Turned Hero: “We Once Thought it Was Junk”

You won’t believe this one. According to evolutionists, millions of years ago a retrovirus infected our ancestors’ genome causing disease, but then through the usual random events, which is to say the usual unknown events, it somehow turned hero and now appears to be highly active and playing a crucial role in stem cells. As one evolutionist admits:  Read more

You Won’t Believe What Politicians Are up to Now

Rep. Rush Holt (NJ), with the help of the atheists at the American Humanist Association, wants Congress officially to designate February 12, 2013 as Darwin Day. And you wondered why our government is a disaster. Holt believes that “Without Charles Darwin, our modern understandings of biology, ecology, genetics, and medicine would be utterly impossible.”  Read more

Here is That New Paper on Synonymous Nucleotides

One of the most common tests evolutionists use, when studying how genes are supposed to have evolved, is to compare the non-synonymous and synonymous genetic differences. That is, if a gene that codes for a particular protein is found in several species, then evolutionists interpret differences in the gene, across those species, as the result of mutations in the evolutionary process. And while most mutations cause a change in the resulting protein amino acid sequence, some mutations do not affect the amino acid that is coded for. These two kinds of mutations are referred to as non-synonymous and synonymous, respectively, and their relative proportions are important to evolutionists. They believe that the while the non-synonymous mutations are important, because they Read More ›

Genes Code For Many Layers of Information

Your internet line carries multiple signals simultaneously and likewise a gene carries multiple biological signals. A gene does not merely code for a protein. As difficult as it would be to randomly find a protein-coding gene sequence, it would be much more difficult to find a real gene because they carry so many more signals. For instance, the gene’s DNA sequence determines the important stability of the DNA copy—the so-called mRNA strand, and the mRNA interactions with proteins such as editing machinery.  Read more

A Marine Mollusk Grinds Down Rock

Algae do not merely grow onrocks, they also grow in the cracks and crevices of rocks making the seaweed organisms a difficult meal for consumers such as Cryptochiton stelleri, otherwise known as gumboot chiton, a marine mollusk off the coast of California. This tenacious chiton solves the problem by grinding down rocks with an amazing set of teeth which contain the hardest known biomineral, magnetite. The outer shell of the chiton’s teeth, as professor David Kisailus explains in his latest paper, develop in four distinct stages:  Read more

For Evolutionists, Crime Does Pay

Why is there no debate over evolution? Why does everyone believe in the Epicurean vision that the world arose spontaneously? Just ask David Coppedge, the IT guy at the Jet Propulsion Laboratory who dared question evolution. Coppedge was an excellent employee who enjoyed his job, but when he openly questioned … Read more

If You Understand Nothing Else About Evolution Understand IFF

Should Christians reject evolution because it violates the Bible by leaving no room for Adam and Eve and the Fall, or should Christians accept evolution because it is the obvious scientific conclusion? That, according to one history professor, is how the debate will be framed at an upcoming conference. If so, it would be an unfortunate repeat of a centuries old false dichotomy and what would be missing would be any discussion of what evolution really is.  Read more

Trending: Evolution’s Information Technology

Art may not imitate life but evolution certainly does. Once the leading edge in biology was breeding and so evolution was cast as a natural breeder. Now the state of the art is genetic engineering and, so, evolution is cast as a natural genetic engineer. And of course the unquestionable trending topic of our time is Information Technology. Just check the employment pages. Do you know Networking, Epic, SAN Citrix, Notes, NextGen, BES, Android, VMware, TCPIP, UNIX, Windows, Active Directory, EMC, Peoplesoft, iPhone, iPad, LANWAN, blade, VoIP, CAT5 and Avaya? If so then you’re trending. And so is evolution. After all, as Matt Ridley explained, “it’s from information technology.” Or as Paul Davies writes this week, “Life’s origins may only be explained through Read More ›
