Our next installment of bad evolutionary arguments comes courtesy of dang near half the commenters in the super-long debate thread in which I've been busily embarrassing the naturalist crowd.
I had asked what commenters' favorite lines of evidence for evolution was. A few responses showed that Hox genes were up there.
I asked neil, who has also done some commenting around here, to "explain how specifically this supports the idea that there *WAS* a common ancestor many billions of yrs ago". He answered:
Because of the pattern of those genes in living organisms. There is a clear predictable pattern of their distribution. Patterns of differences in sequence and duplications are perfectly consistent with what common ancestry predicts.
This is the same pattern repeated for other genes, ERVs, for pseudogenes (found out what they are yet?) etc.
So what's the big deal with Hox genes? They "(define) a region or position in the embryo", thus influencing more or less what parts grow where in the developing baby organism.
It's not my intention, nor is it very interesting to me, to re-summarise what Myers said in the linked article, but apparently evolutionists find it very significant that they can exercise their powers of assumption with Hox genes as their foil.
Just look at how Myers himself makes the running leap straight into midair:
There are also a few gaps; with duplication comes redundancy, and the possibility of deletion without detriment, and so we also see some examples of culling duplicates in our history.
Speaking of history, one of the things we can do with a phylogenetic analysis of the Hox cluster is see fascinating aspects of our ancient history...The anteriormost and posteriormost genes in the complex are the most different from one another, so we can surmise that they diverged earliest, and have had the most time to accumulate differences.
To repeat, the question at hand here is this: Is the data best explained by the hypothesis that a Designer DID all this, or the hypothesis that unguided natural selection working on random mutations DID all this? We're asking about what happenED. Notice that there is no argument given to take us from Point A to Point B in this.
The fact - Hox genes exist.
The interpretation - They diverged early on.
But what about...?
The interpretation - The Designer made them that way. To almost quote neil, but to go ahead and take him to the logical conclusion he so fears, "Patterns of differences in sequence and duplications are perfectly consistent with what a Designer hypothesis predicts."
Only two answers have been given so far, and I'll discuss the other one in my next BEAR post.
For now, today's answer is perhaps best revealed by neil.
No not with what a designer predicts. Only with what a designer mimicking common descent would predict.
That is precisely the point. Neil here concedes that the data is just as well explained by a Designer.
It looks like it could have evolved. Sure, whatever, fine. A Designer could also have done it. When I ask for proof for evolution in the context of a debate about ID, I'm expecting you to share some of your "mountains of evidence" with me that could not just as easily be evidence for ID. Get to work.
