Just to throw in another ...I'm not entirely sure of how to articulate everything, but this is how I see it.
I don't believe in an evolution where information is magically created from mutations.
No magic. Just changes. Any new mutation in a population adds information to that population. If you want to see the calculations, I can show you how it's figured. But a new mutation, if it reaches fixation can decrease information when that happens. In reality, any time an allele reaches fixation (no other alleles exist in the population for that gene locus) there is a loss of information. But usually, in a healthy population, information increases. Evolution is really neutral as far as information goes.
It's important (at least for me) that we make a clear distinction between Darwinism and modern evolution because both systems tend to be mixed and used interchangeably when there are some important differences.
Darwinism isn't about mutation. He had no idea that genetics was particulate rather than humoral. So the modern theory is mostly Darwin's theory plus genetics.
The odds of mutations being the driving force for evolution are pathetically low.
It's the source of variation, without which, no evolution. And without natural selection, mutations would quickly destroy a population.
Mutations are frequently harmful. If you change the code, it's likely that you're going to get a combination that doesn't work.
Usually. But it's rarely harmful. Most mutations don't do very much. Cytochrome C, for example, has had many mutations, and exists in a variety of kinds, but they all still work. There are some sites on the molecule, though, that can't change because they change its function. And that is lethal, because it does a very specific thing in energy transformation in the cell.
This of course isn't the only issue...because sometimes you're going to get a combination that does work. Statistically speaking, it's bound to happen at some point. The issue is that a single mutation has to spread across an entire population. This requires a whole bunch of fortuitous bottlenecks happening at regular intervals in our history...and the history of other animals. The whole thing is rather miraculous.
Would be, if not for natural selection. Natural selection is quite capable of removing the harmful alleles and keeping the useful ones. Because many alleles are so close to harmless that we can't measure their selective value, it means that a lot of them stick around. And harmful alleles are recessive, which means there isn't a huge problem, unless a lof people marry their cousins. If Lynch is right, this is really a good thing, since it produces enough variation to assure survival in a world filled with evolving parasites and disease organisms.
What makes a lot more sense to me is that the genetic information exists already, and based on the environment, certain genes are switched on and off. In fact, I read an article a while back (I wish I could find it) that explained how cells actually make these changes proactively! We've found evidence that they're aware of their environment and can switch these genes on and off on their own.
Actually, the cell doesn't do it. There's a regulator of some sort that causes the switch to turn on or off, in the presence of certain things. This is not evolution. Evolution is when the allele frequencies in a population change.
In the end though, this has nothing to do with whether or not God created the universe.
True.
