So, Dr. Zassenhaus is teaching right now in my lecture class about basic Mendelian genetics. He told us earlier this week that he was making a presentation today in reference to Intelligent Design and Evolution, so I’ve been looking forward to this all week because I haven’t heard much discussion amongst Ph.D. scientists that I know and the sources I’ve read through discussing the subject rarely consult pure molecular biologists and biochemists…and I came away from the presentation with a few interesting points…
First of all, Zassenhaus began the discussion talking about the Kreb’s Cycle. For those who don’t remember, this is a pathway in mitochondria (an organelle in our cells) that converts relatively simple carbon chains into other forms, generating ATP, which is the “currency” that creates energy in our bodies. Since it is a cycle, the products begin in one state, are converted to another state, and are then returned to their original state to start the cycle once again. One of the classic Intelligent Design arguments is that this process is not reducible; one cannot remove a part of this cycle and still have it function, leading them to suppose that an intelligent creator must have created this pathway. The process couldn’t have simply “appeared” on its own, already functioning.
The problem with this assumption, as Zassenhaus further enumerated, is in the fundamental argument for Intelligent Design: that life is too complex to have just happened. The argument, as he states, is the classic “Watchmaker Analogy,” such that if you are walking in a field and see a watch, you know that it didn’t simply appear, but that someone had to make it. The problem is that all of Intelligent Design arguments stem from that one analogy. There is no evidence besides it. The one scientific study he could find that tried finding true evidence was carried out by a mathmetician (Dembski) who said that the chances of such a thing appearing is something like 10^-170 (that’s one time in 1,000,000[continue to 169 “0”s…]), which is unbelievably small…bordering on impossible…
As Zassenhaus concluded, these probabilities outline a huge flaw in the thinking: where Intelligent Design advocates believe such a pathway just sprung into existence, and was created by someone else, biologists for years have viewed the formation of proteins/enzymes/etc. differently, as individual subunits that are added on and removed to provide a different function that wasn’t there originally. Therefore, those statistics don’t apply to the way we know biology to work. Sure, it says that such a thing as the Kreb’s Cycle appearing out of a soup of random amino acids is really small…but the chances of a different protein forming out of that soup is very possible, and then that protein adding on other parts of different proteins is also possible…slowly adding together to form the pathway we know as the Kreb’s Cycle.
In short (’cause I wasn’t, overall…), the moral is: Intelligent Design advocates have yet to produce true, testable, scientific evidence beyond the flawed probability studies. Is Intelligent Design still possible? Of course it is! But, as Zassenhaus said, teaching it alongside Evolution on equal footing as a viable scientific theory is, quite simply, nuts. In that room of 20+ Ph.Ds., there were none that defended Intelligent Design in the way it has been portrayed as a science. They all believe it should be relegated to a philosophy class, not the science classroom. Unfortunately, the “powers that be” refuse to listen to the scientific community on what should be taught and what shouldn’t be.
Figures…
So, in that vein, can anyone give me evidence to the contrary that isn’t based on “evidence by analogy?” I know that Andy S. already gave me information on another theory…hehehehe…
