PZ Myers: The Anti-Authoritarian Authoritarian

Is there a religious influence and authoritarian tradition in science? Evolutionists such as PZ Myers reject any such notion. Though Myers relies on the usual theological truth claims that are fundamental to evolution, he is sure that science is free of all such nonsense. When he is not busy shutting down scientific inquiry with religious dictates, he reassures his readers that science is a process that empowers questioning and change.  Read more

The Evolution of Evolutionary Thought: Why Historians Analyze Evolutionists But Not Evolution

One of the reasons evolutionists are convinced their theory is true is because of the way the species compare to each other. The patterns we find amongst the species, say the evolutionists, prove Darwin’s idea beyond a shadow of a doubt. Such arguments pervade the evolution genre—from textbooks to popular literature—but what exactly do they mean? To understand this we must understand the evolutionary mind. These arguments have circuitous histories and baked-in assumptions that are now long forgotten. But they are worth remembering. Here is one example.  Read more

DNA Methylation in Bacteria

How do bacteria respond to environmental challenges and signals so quickly and effectively? In addition to genetic modifications there are a series of non genetic, or epigenetic, modifications. Genetic modifications change the sequence of nucleotides that, for instance, comprise a protein-coding gene. In that case the resulting protein is modified to better handle the environmental challenge. Epigenetics, on the other hand, involves various other types of modifications. For instance, the three-dimensional structures of proteins may be dramatically altered, or tiny chemical signals—methyl groups—may be added to certain proteins or DNA sequences. As with genetic modifications, many of the epigenetic modifications are heritable, so the adjustments are passed on to later generations.  Read more

What You Think You See is Not What You See

Those textbook diagrams showing the supposed evolution of vision reveal a real blind spot, for there are big problems with this evolutionary narrative. For instance, the biochemistry, even in primitive eyes is numbingly complex. The notion that it evolved is nowhere motivated by the scientific evidence.  Read more

Why Evolutionists Say Evolution is a Fact

Evolutionists say evolution is a fact, every bit as much as gravity is a fact. That is remarkable. We see and even feel gravity everyday. Evolution, on the other hand, entails rather dramatic, one-time, events that were supposed to have occurred long ago, when no one was around to witness them. How could we be sure of such a theory? There must be some extremely powerful and compelling scientific evidence for evolution to make it a fact as gravity is a fact. That is what one would think. But, surprisingly, there is no such evidence. When evolutionists try to explain why evolution is a fact, it is a tremendous anticlimax. Consider this example from evolutionist Massimo Pigliucci:  Read more

Scientific American: The Banality of Evil (ution)

Katherine Pollard’s Scientific American article from last year, about what makes humans different from chimpanzees, is an unfortunate example of the banality of evolution. Charles Darwin’s theory, updated to account for a variety of surprise evidences, is taken as fact and this leads to a remarkable level of credulity. Whatever we find in biology, it must be the product of evolution. This leads evolutionists away from a whole range of possible investigations and interesting questions. Instead, they drone on with the same, tired, evolutionary explanations that are so predictable. Here are a few passages of note from Pollard’s article:  Read more

Evolution’s Appeal

Scientific problems with evolution don’t really matter. This genre of thought scratches too many itches to let science bring it down. Traditionally those itches have mainly been theological and philosophical. Now, as the evolutionary narrative subsumes human nature, new itches emerge. Geoffrey Miller, an evolutionary psychologist, provides a peek into this latest addition to evolution’s appeal. This quote appears in a fancy, inside cover advertisement run by the John Templeton Foundation, in the May 2009 Scientific American:  Read more

Histone Inspectors: Codes and More Codes

By now most people know about the DNA code. A DNA strand consists of a sequence of molecules, or letters, that encodes for proteins. Many people do not realize, however, that there are additional, more nuanced, codes associated with the DNA. For instance, minor chemical modifications (such as the addition of a methyl group) to the DNA provide bar-code like signals to the protein machinery that operate on the DNA. This DNA methylation influences which genes, along the DNA strand, are read off. And this DNA methylation itself may be modified to provide additional information.  Read more

Does the Evidence Support Evolution, or does Evolution Support the Evidence?

For all their disagreements, evolutionists strongly agree that evolution is a fact, just as gravity is a fact. There is no question that evolution occurred. And since evolution is as certain as gravity, those who do not assent must not be rational, or they must have ulterior motives. If there are scientific questions about evolution (and there are), they merely relate to the question of how evolution occurred, not whether evolution occurred. Those who point out that the scientific evidence does not bode well for evolution must understand that such evidence can in no way call the fact of evolution into doubt. The scientific evidence can only bear on questions of how evolution occurred.  Read more

Junk DNA: The Real Story

By now you have probably heard about so-called junk DNA. In recent decades the genomes of a growing number of species have been mapped out. Not surprisingly, scientists did not understand how many of these DNA sequences worked. For instance, repetitive sequences are common, but what do they do? As these data accumulated evolutionists increasingly viewed such sequences as useless junk. Then, years later, various functions began to emerge as our knowledge grew. This junk DNA story is the latest version of what seems like a repeating bad dream that goes like this. Scientists discover something new in biology but don’t understand it. Evolutionists, unaware that they are staring at a design whose complexity dwarfs their puny understanding, decide it Read More ›

Evolution: A One-in-a-Billion Shot

It is no surprise that there are scientific problems with evolution. Its predictions are continually turning out to be false. It undoubtedly ranks number one in faulty expectations. For instance, one of its primary predictions, common descent, has badly failed. The reconciliation of the molecular and the visible, morphological, features has been a major problem in trying to resolve the evolutionary tree. The molecular and morphological features often indicate “strikingly different” evolutionary trees that cannot be explained as due to different methods being used.  Read more

Evolution and Evolvability: A New Kind of Science

The basic idea behind evolution is rather simple: in times of difficulty not everyone survives, or at least not everyone reproduces. Those who are faster, bigger, taller, stronger, smarter, or whatever it is that makes for successful reproduction, will do just that. And those who lack the requisite capabilities will not reproduce, or not reproduce as prolifically. One way or another, the result is that, in those difficult times, future generations are more representative of the winners. The traits of the successful reproducers are passed on more often. This means the population undergoes a change—it evolves.  Read more

The Genome of a Microbial Eukaryote: You Can’t Make This Stuff Up

New research is confirming the evolutionary conundrum of early complexity. The research shows that a microbial eukaryote, Naegleria gruberi, shares a large number of genes in common with other eukaryotes. And why is this a problem? Evolutionists have resorted to many incredible just-so stories of convergence. From intricate spider web designs to entire vision systems, evolutionists have been forced to say such designs, because they are found repeated in distant species, have evolved more than once. And while the supposed independent evolution of these striking designs is silly, even these evolutionists have not yet said that similar genes evolve independently. Until and unless they resort to such a fantasy they must say that similar genes in different species have arisen Read More ›
