Chalnoth, dealt with your claims and arguments very well, but I just wanted to play as well.
Again, this is the typical response of the opposition to anyone who questions any tenant of evolutionary theory. The problem is that the primary rationale for neo-Darwinist evolution through random mutations and genetic drift...is the lack of conclusive evidence of non-randomness, intentionality or design.
The lack of conclusive evidence for hyptheses #2 and #3 doesn't constitute support for hypothesis #1. It violates Chamberlain's Rule of Multiple Working Hypotheses.
Random mutations happen. Spread a culture of E. coli on a plate with a certain antibiotic and nutrients and incubate it for a few days. The result is a few surviving colonies that have developed resistance due to random mutation. You can also apply a mutagenic agent like UV light for instance, which will increase the number of mutations and thereby number of surviving colonies. These simple experiments doesn't need any other guiding forces than the light randomly cutting DNA and the cells trying to repair the damage often resulting in mutations. You're free to believe some God is directing these light beams towards specific places on the DNA strings and guiding the enzymes in such a way that these mutations somehow
always seem to happen within a certain probability distribution, making it look completely random, go ahead and believe that. But before you can show that these processes are directed, "random" is how it looks and how best to describe it.
Genetic drift is inferred from evidence and holds explanatory power. And you neglected to mention natural selection in your entire post, which is of course overwhelmingly supported by both evidence and logic.
These things certainly aren't accepted based on the rejection of other things, but because they are well supported on their own and holds explanatory and predictive power.
If evolution is driven by an external (or innate) intelligence...and that intelligence happens to be God...Then the banishment of the subject from the classroom is a War on Science.
Science requires evidence. It could be that your God somehow interferred with the process of evolution, or that magical gnomes did it, or we could just as easily suggest an infinite number of other unevidenced explanations. But without evidence it's not science, and shouldn't be taught as such.
We don't know what drives evolution of species. We pretty well know what drives evolution within species.
It's the exact same process, simply on a longer timescale. Within species variants naturally arise when there's a geographic barrier or distance that prevents or complicates interbreeding. Sooner or later the populations will be so different that the members won't be able to produce fertile offspring together even if the geographic barrier is removed. These things has been observed, it's not just in theory.
I don't have any problem at all with teaching that the neo-Darwinist hypothesis is the most widely accepted version of evolutionary theory. I do have a problem with the dogmatic defense of neo-Darwinism as the only acceptable theory.
Thing is, the TOE is the only
scientific theory that explains biodiversity. If there was a valid alternative, supported by the same amount of evidence, it would indeed deserve equal time. But there just isn't. ID is as far from science as it gets. It's untestable, unfalsifiable, unevidenced, subjective speculation and it's proposed in a fallacious manner (i.e. argument from ignorance and false dichotomy). There's no scientific work done using ID, there's only an effective propaganda machinery that strives to increase public pressure on politicians to force it into science class. This cartoon illustrates the issue quite nicely:
If God did it...God is not supernatural.
If the universe has a collective consiousness...it's not supernatural.
If it's random mutation and genetic drift...the fossil record shouldn't constitute clear evidence of punctuated equilibrium.
Actually the evidence both indicates instances of phyletic gradualism and of punctuated equilibrium (which is also gradualistic, but with greatly varying speeds). Gould made some good points, though he was quite the provocateur using too strong language from time to time and often had to back peddle and clarify. Notice however that even though he misbehaved like he did, his (and Eldredge's) ideas were considered and absorbed by many scientists. This fact alone shows clearly that evolutionary scientists are anything but dogmatic, even though Gould loved calling them that.
