I hear you, but ID fails for a lot of reasons, most notably that it isn't a scientific theory. Proponents of ID haven't even bothered to pretend that it's a coherent theory masking as science. Usually the argument boils down to "this is too complex to be described by evolution." See any post by MasterofOrion and his various estates.One of his favorite claims is that the "designer" (coyly not referred to as "God") spontaneously introduced information into the genome of living systems. I don't know if it's been described in more mechanistic detail than that, but I think the idea is that the hallmarks of a "God event" exist if you start looking at things like the Cambrian explosion. The trouble with this specific example is that 1) we don't have DNA from 500-600 million years ago, and 2) the fossil record suggests that this period of rapid evolution was over the span of tens of millions of years (suggestive of a marked increase in evolutionary activity over that time, but not an abrupt step change).'Bottomfeeder Sports said:What is Windows NT? When things start getting complex in a designed world, good designers absolutely start over to eliminate or at the very least hide that complexity. This is exactly where ID fails. The argument that complexity equals design is completely backwards. Simplicity is the result of design, complexity is the result of systems that are evolved.I don't know that I can answer the WHY. I'm sure when the Madden 2013 programmers start their programming, they don't start over, they take the existing programming from Madden 2012 and than add to it. But I'm not going to go down that route too far, because I didn't design humans.
Leaving aside the Cambrian period and its lack of direct genetic evidence, a persistent ID claim is that new species arise because they are designed and directly implemented. From what I have read, how this mechanistically occurs is never articulated, but the argument is that it must be this way because evolution as a theory cannot account for what we observe. This would imply that God -- sorry, the designer -- is continually at work fiddling with the DNA of living things to produce new species and traits all the time. One would assume (I'm not up on the most common claims) that these events would be discrete in nature where you'd find abrupt step-changes in the appearance of species and their corresponding genome. That is, one day something wouldn't exist, and the next day it would exist in grand fashion. Of course, this isn't supported by observation. I think it was an easier idea to float into the mainstream in the day when there were fewer very old fossils to point to (where things do look discrete in a sense due to limited samples), but given the wealth of accessible DNA, we have a much better idea of the progression of life on earth, and certainly we don't see spontaneous appearances of vastly new genomes that show up out of the blue. In fact, one of the most compelling aspects of evolution and the underlying genetics is that there are so many genes and other segments of DNA that are highly conserved, even among seemingly disparate species.
All of this is prelude to the statement that a designer (God, Spaghetti Monster, what have you) would likely leave a definitive stamp of their work in the genetic code. It would be unambiguous and consistent with discrete events. Rather, what we find is this slow progression of accumulated genetic changes that are consistent with the mechanisms that comprise evolution. To think that an intelligent designer would hide their work so carefully so as to appear to be due to an entirely different process that omits a guiding hand is preposterous on its face. In fact, that idea starts to sound a lot like the curious young earth creationist argument that God build the earth to look old. You know, to test our faith.
In science, theories are developed that can potentially be falsified. Evolution is such a theory. The general framework of evolution has persisted for roughly 150 years, even in the absence of genetic theory. Once we added our understanding of DNA, the theory of evolution was dramatically strengthened, especially because it could be tested in countless new ways with very specific expectations. The potential for falsification grew orders of magnitude, yet it persists. Yes, our precise understanding of genetic theory has changed with new discoveries, but the theory as a whole is surprisingly similar to Darwin's first description in 1842. It's an astonishing achievement given the limitations of the available knowledge at the time.
I'm still confused by this suggestion that God shows up to fiddle with DNA every so often. It's a little unnerving, actually.
