In a way it was a crazy question to ask if macro-evolution is true. After all, they are not closely related. They are about as far apart as they can be and still be in the same class of organism. As the article concedes, these two groups would have evolved echo-location independently of one another, so what would the odds be if they used more than a few of the same genes to do it?
The vast number of genome regions which have to change together to successfully acquire the ability to echo-locate is problem enough for the macro-evolutionary hypothesis. The results of their study astounded them and made the macro-evolutionary hypothesis even harder for thinking people to accept. It turns out almost 200 genomic regions were virtually identical in the two groups of organisms. "We had expected to find identical changes in maybe a dozen or so genes but to see nearly 200 is incredible," explains Dr Joe Parker, from Queen Mary's School of Biological and Chemical Sciences.
They chalk it all up to the power of evolution of course, because they have an "evolution of the gaps" bias. Whenever they see something that "astounded" them, as this did, they chalk it up to the power of evolution via some undefined pathway. They called this an example of "evolutionary convergence". Honestly though, a finding like this gives a lot more support for the Intelligent Design Theory. That is, two vastly dissimilar organisms can share the same genes because they had a common Designer, who used a similar idea for a similar function in the same genes of the two groups. Under that scenario, it is not necessary for the two groups to have had a common ancestor in order to wind up with the same genes.
Evolutionary convergence used to mean animals which were not related had a similar form due to performing similar functions. The classic example is sharks and dolphins. Their physical forms were shaped in a similar way by a common function. Evolutionists are trying to shoe-horn this idea into the exciting findings they are making in genetics. But it doesn't fit. There is no reason to expect that the same genes would be adapted in both species for such a novel function as echo-location. It is basically describing "conservation" of individual genes that were not inherited from a common ancestor, which of course goes against the very definition of conserved genes.
Example: If I build a grandfather clock from metal shards, and a man in China does the same, the faces of our clocks may look alike, but there is no reason to expect that a specific part from my clock would even exist, much less fit, in his clock. Evolution shapes the end result, but the means to get to that result are supposed to be random, chance changes being selected for or against by the environment. When the means are the same, it is a mark against the hypothesis, or would be if they were not trying to rig the terms of the debate so that no matter what the evidence shows, "evolution did it". That's an "evolution of the gaps."
It is just a way of saying that whatever happened, evolution did it. If sharks and dolphins look similar but have different genes to breath, why evolution produced the differences, while if dolphins and bats use the same genes for echo-location, why, evolution did that to. It makes the idea impossible to falsify via the scientific method. Which of course, means that it is no longer science at all.

This article is not directly related to the Christ-centered model for early Genesis as described in my book. Still, I ask you to get the book...
The study found more than 200 genomic regions that were virtually identical. They expected convergent evolution to produce maybe a dozen but they found 200! Naturally their conclusion was just that "convergent evolution is just more powerful than we thought." Because whatever happened, evolution did it. But when the results surprise so much, and so outstrip the power of the known mechanisms, the fair-minded person might wonder if they are missing something. If there is an unseen hand in all this using similar solutions for similar problems in species which are not at all close on the evolutionary tree.
ReplyDeleteThe point about the theory of evolution having predictive power is sort of working against naturalists here. If a dozen are predicted and 200 are found that's not a very accurate prediction. It points to something beyond the process you are putting all your chips on being involved. The earth had help in bringing forth kinds. It looks like evolution from some angles, but it wasn't just nature. Nature had help.
