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.
Evolutionist Ian Musgrave has the explanation for this unexpected finding. Illustrating the bend-but-don’t-break property of evolution, Musgrave explains that those truly unique genes that we find are actually de novo genes.
Of course, I should have thought of that—de novo genes.
But wait, isn’t that the point? Aren’t de novo genes an unexpected finding? Of course they are. They arise entirely too fast, and those de novo genes for whose origin which we have some understanding reveal anything but evolution. Indeed, there is compelling evidence that new genes can be manufactured in response to environmental pressures. You can read more here.
You’ve probably heard that evolution has not been falsified. That’s true—it is the predictions of evolution that have been falsified. Evolution is a fact.
