Common descent is well supported by the evidence in the broken GULO gene (along with myriad other independent lines of evidence in the haplorhine primates). The fixed mutations in the broken gene form a nested hierarchy that matches phylogenies for functional genes. Interestingly, the substitutions differ from those in guinea pigs, which appear to have had an independent loss of GULO. These threads of evidence amount to more than claiming that common descent is only better than pure chance.
But common descent is, in fact, not “well supported” by this evidence. Evolutionists continue to repeat their mantra, but this evidence does not support common descent anymore than a pig with a cold nose supports the claim that pigs can fly. It is true that if pigs can fly, then we would expect to find pigs with cold noses. But we would hardly conclude that the hypothesis that pigs can fly is strongly supported by pigs with cold noses.
Nor do the “independent lines of evidence” support common descent any better. Indeed, the evidence leaves little doubt that what seemed obvious is, in fact, obvious. Common descent not only is intuitively silly, it is scientifically silly as well.
There is, for starters, that little problem of mechanism. Though they can’t supply the details, evolutionists say that a long, lucky, series of garbled, random mutations and other flukes of variation led to the millions and millions of species with all their incredible designs.
Or again, there is the problem of the biological patterns that don’t fit. From the striking similarities found in distant species to the profound differences in otherwise allied species, the predictions of common descent have been falsified many times over.
If ever there was an idea that doesn’t work scientifically, this is it.
It is true that there are patterns that, when taken in isolation, do fit common descent. The vitamin C pseudogene is an example. But this doesn’t magically dissolve the multitude of scientific problems. Yes, the evidence is consistent with common descent, but so too is the rising sun consistent with geocentrism.
As if sensing a problem the evolutionist, in typical fashion, makes a quick switch to metaphysics with a series of rhetorical questions:
If we were to reject common descent, is there some theory dealing with common design that provides a better explanation for a shared, broken gene in a line of otherwise apparently closely related species?
This is the heart of evolutionary thought. It is not that evolution makes sense (it doesn’t), it is that evolutionists believe it is the only choice. Rhetorical questions such as this one are common with evolutionists. A key to understanding evolution is that evolutionists think this line of reasoning is scientific, that such questions can be answered with a high level of certainty, and that in particular the answer is “no.”
But of course, contra evolutionists, science has no way of making such ultimate truth claims. It cannot know all possible explanations. As such scientists do not make sweeping claims that no such reasonable explanation is possible for observations, such as the vitamin C pseudogene patterns. Evolutionists, on the other hand, do.
Another evolutionist wrote that the vitamin C pseudogene pattern is a prediction of evolution given that it is found in certain species. He writes:
For example, given that humans, gorillas and orangutans all have this pseudogene, common descent predicts that chimps will also have it.
This seems reasonable, but since evolution and common descent have made so many false predictions, then certainly we must conclude they are false by modus tollens. If evolutionists use successful predictions to promote their theory, then shouldn’t the many false predictions mean something?
Religion drives science, and it matters.
