Jerry Coyne: Human Embryo Has Gill Slits

In his 2009 book Why Evolution is True professor Jerry Coyne, whom people pay to teach their children, informs his readers that “All vertebrates begin development looking like embryonic fish because we all descended from a fishlike ancestor with a fishlike embryo. We see strange contortions and disappearances of organs, blood vessels, and gill slits because descendants still carry the genes and developmental programs of ancestors.” [79] There’s only one problem: it isn’t true.  Read more

Are Gill Slits Really Powerful Evidence for Evolution?

A few years ago I debated an evolutionist who claimed that the human embryo’s gill slits are powerful evidence for evolution. The idea is that as new species evolve, their embryonic development tends to build upon the embryonic development stages of the ancestral species. Imagine a 10-story building is constructed, and then years later a few more stories are added to the top of the building. The first 10 stories would remain unchanged. Similarly, nineteenth century evolutionists expected that the embryonic development of an organism would reflect its evolutionary history.  Read more

Why Eyes Did Not Evolve in the Back of the Head

In a recent Scientific American (July, 2009) “Ask the Experts” column, evolutionist S. Jay Olshansky explains why humans have not evolved eyes in the back of the head. Olshansky makes the argument that (i) natural selection is limited to those designs that just happen to arise and (ii) what happens to arise is not driven by need. In other words, we don’t have eyes in the back of the head not because they wouldn’t be useful, but because early versions never happened to arise there in the first place.  Read more

Origins of the Left & Right Brain

A recent Scientific American article (July, 2009) explains the evolutionary roots of your right and left brain. The article, written by three evolutionists, explains that it was once thought that the hemispheric specialization of our brain (e.g., language in the left hemisphere, spatial thinking in the right hemisphere) evolved in our hominid ancestors, over the past few million years. But it now appears to have evolved orders of magnitude farther back in time. Why the half a billion year change? Mainly because of the accumulation of evidence of hemispheric specialization in a wide array of species. “So what” you ask?  Read more

Falsifying Evolution and Moving Goalposts

Falsificationism has always been an important part of science. Many scientists argue that if a theory cannot be falsified, then it does not qualify as genuine science. That view may be overly simplistic—and it is not falsifiable by the way—but certainly falsificationism is an important tradition within science. Theories are based on empirical data, and it is the empirical data which should have the final say on whether the theory makes sense. Therefore it is curious that evolutionists, while insisting on falsificationism for theories they oppose, suddenly drop this favorite criterion when it comes to their own theory.  Read more

Retrotransposons are not Free

You may have been taught in your high school biology class that DNA point mutations provide the raw material for evolution. Such mutations can cause biological variation which might lead to improved reproductive rates. In those cases such mutations would likely be selected, and evolution would have taken yet another small step. You may have wondered how such unguided point mutations could ever produce the wonders we find in biology. The answer, evolutionists will tell you, is that point mutations are only the beginning of the story. In fact there are a variety of mechanisms, many far more complex than a DNA point mutation, that can produce biological variation. For instance, new research has found that so-called jumping genes, or Read More ›

Evolution and Entropy: The Magic of Sunlight

Does the second law of thermodynamics pose a problem for evolution? Daniel Styer doesn’t think so. In fact, in a recent paper he found that any entropy decrease here on Earth due to evolution would have been dwarfed by the entropy increase of solar radiation contributing to the cosmic microwave background. He writes:  Read more

Arguing with Evolutionists or How I Could be Rich

If I had a nickel for every time evolutionists insisted that they are merely following the evidence, immediately after (or before) making religious arguments, I think I would be a zillionaire. You can read about Jerry Coyne and PZ Myers insisting on their innocence here and here, but this self contradiction is not limited to the big shots. From laboratories to sanctuaries, and dorm rooms to chat rooms, the constant refrain of evolutionists is that the raw data make their idea a fact, but then the supporting arguments are religious. Evolutionists are the proverbial fish that doesn’t know it’s in water, the lampshade partier who doesn’t know he is drunk.  Read more

ORFans and the Theory That (Never) Predicted Them

Because similar species are thought to share a relatively recent common ancestor, they are assumed to have not had much time to evolve differences between them. That explains why they are similar, and it also predicts that such species do not have significant differences. Their genome differences should be minor. This is because evolution is limited by the rate at which genetic variations can appear and subsequently spread throughout the respective lineages. But we now know of significant numbers of unique genes between allied species and even between different variants within the same species.  Read more

Explosive Evolution of Whales Followed by Little Change

You know the drill, new forms appeared rapidly followed by little change. This time it’s whales, the late comers turned allstars of the ocean. Somehow the whale ancestors lost their hind limbs, grinding teeth and pelvises and developed a host of new features with great efficiency. These new features include the fluke tail with its unique vertical propelling motion, the huge filter-feeding jaw, and the ability to give live birth and raise its young in the marine environment. All this while acquiring superior skills in its new marine environment. The latest entry to the community could swim, dive and feed better than most fish and sharks. It all just happened to happen, and with great evolutionary speed.  Read more

A Compass That is Never Right

What good is a compass that is never right? Evolution certainly is not that bad, but it is telling how often Darwin’s idea, mandated to be a fact, is so far off base. Consider for example the kangaroo genome, which turned out to be similar to the human genome. As one evolutionist explained:  Read more

See No Evil, Hear No Evil, Speak No Evil

Just as Charles Darwin dealt with difficulties with his theory of evolution in Chapter 6 of Origins, so too Denis Alexander deals with objections in Chapter 6 of his book Creation or Evolution. And just as Darwin’s logic was often questionable, so too is Alexander’s. The chief problem is Alexander’s rather selective presentation. For an author of a book about the origins controversy, Alexander seems to be remarkably unaware of the actual debate.  Read more

A New Model for Evolution: A Rhizome

Evolutionists have a problem. Their theory doesn’t fit the facts, yet it must be true. They have to constantly change their story, all the while insisting it is a fact. Like a Heraclitean flux, it is constantly changing and yet always called the same thing. Evolutionists are continually surprised by the science, yet they euphemistically call this “progress.” A recent article in The Lancet, suggesting that evolution is like a rhizome, is a good example of evolution’s folly that is so obvious.  Read more

DNA Rules of the Road and Incredulity

Every biology student learns of two massive machines that operate on the DNA molecule. There is the transcription machine that makes a single-stranded copy of a gene, and there is the replication machine that makes a double-stranded copy of the DNA double helix. The former is the first step in the protein synthesis process while the latter is part of the cell division process. But what happens when these different machines meet as they operate on the same stretch of DNA? What are the rules of the DNA road?  Read more

Horizontal Gene Transfer and the Evolution of Evolution: You Can’t Make This Up

What do bacterial resistance to antibiotic drugs and the universal genetic code have in common? They both have been explained by horizontal gene transfer, a mechanism that evolutionists are increasingly using to explain the origin of the species. And what’s wrong with that? First, it makes evolution superfluous and second, it makes evolution ridiculous.  Read more
