Study Explains Evolution's Molecular Advance
pnewhook writes "The New York Times is reporting that 'by reconstructing ancient genes from long-extinct animals, scientists have for the first time demonstrated the step-by-step progression of how evolution created a new piece of molecular machinery by reusing and modifying existing parts. The researchers say the findings, published today in the journal Science, offer a counterargument to doubters of evolution who question how a progression of small changes could produce the intricate mechanisms found in living cells.'"
It's also immensely disrespectful to our ancestors of well over a million years' span, to deny their existence because it just might, maybe rock the boat a little.
How many thousands of generations of people lived and died over the millennia so that we might be where we are today? And some would deny their very existence. Shame on you!

To be fair, evolution does not disprove of A god...
But it does kinda reduce the likelihood that there is a PERSONAL god who is intimately concerned with all of our activities, and so is a reason to behave in a moral way and more importantly, to then worship that god and tithe to the church who claims to be the bridge between man and god.
(Note, I was not saying that atheists are not moral with the "is a reason to behave..." line, but for some people the existance of a personal god is one of the reasons to behave in a moral manner.)

It's worth noting that most mathematicians already think ideas like Irreducible Complexity and Complex Specified Information are a load of hooey, despite the appeals people like Dembski and Behe make to having made innovative breakthroughs in these areas:

One good blog on this subject I've found is Good Math, Bad Math, and some posts relevant to this topic are:
-CSI is basically incoherent: if you translate the definition of CSI into non-obscure words, it essentially boils down to either "something that contains a lot of information, but doesn't contain a lot of information" or a definition for which EVERY piece of information is specified:

-IC, when translated into math, makes no sense. We can actually PROVE in math that there is no general proof that some system is the simplest possible (which IC requires), much like we can prove that we can never solve the halting problem.

-Even if they did make sense, CSI and IC basically conflict with each other, arguing contradictory things:

Personally, I feel like events such as hurricane Katrina, the tsunami in the indian ocean, and September 11th offer a much stronger proof of the lack of a personal god.
Interestingly, other people look at the same events and come to the exact opposite conclusion.
Wierd, no?

Indeed. Most scientists roll their eyes at the use of "missing link" because it obviously misleads far more than it informs. The basic idea is that we have a family tree of life. There are millions upon millions of branches (species), and billions upon billions of twigs (individual creatures) alive over time, but only a very very tiny proportion are still alive today. That means that there is a far far vaster space of animals that died that are NOT the ancestors of any living creature than there are.
Hence, since fossilization is basically a rare and random crapshoot, the chances of finding THE common ancestor are always unlikely, and we can't even reliably tell if we had. But, fortunately, it's also irrelevant. That's because we can learn more than enough simply by finding a fossil that's past a particular branching point about the creatures that led to those we see today. We are trying to learn the general, overall shape of the tree, and since features all tend to be unique to any given lineage, we can still always tell everything we need about the prior branchings from the random sampling of fossils we have.
Currently we have so many that all the basic connections are pretty clear. And when you add in genetic studies that confirm these relations, the conclusion becomes about as rock solid as can possibly be. Creationists often try to confuse the debate over how particular twigs branch with a debate over whether there even is a tree of life pattern and branching at all.
