How did blood clotting evolve?

[FaithfulServant]

no flirting with creationists. It makes for bad karma.

I'm sorry, but where did I state that I was a creationist? I'm just making a thread asking some questions, which were:

Okay ladies and gentlemen - let's not get off topic arguing about whether evolution created the universe or not

Back to blood clotting...

I am familiar with Professor Doolittle's work - he thinks that it happened by random duplication and recombination of gene pieces.

Ignoring the amount of luck that it would take to get the gene pieces in the right places, I am mostly curious how a protein made from a duplicated gene would immediately have the necessary and sophisticated new properties?

If I am right, duplication means copy - so a duplicated gene is simply a copy of the old gene? So where did the new function come from in the production of prothrombin, plasminogen, proaccelerin, etc?

Anyone care to shed some light instead of continuing your own conversation about other evolution topics?

 

[FaithfulServant]

No one has any idea? If not thats okay, just say so.

The OP was answered. Let the thread die.

Actually, it was never answered, some link was posted about Doolittle, which Ive already read,
So I should make a new thread for my new questions?

Perhaps you should go back and read posts 5 & 6 and study the links provided in them. If you don't think that Miller provides an answer please explain why not.

I know this is an old thread, but I just watched something about blood clotting on tv. I will look at posts 5 and 6 (like said above).

But I really can't see how something so complex could possible evolve like that, especially when it is so essential. I don't see how creatures could last at all without it. I'm sure the evolutionists have come up with some excuse for this, but this seems to be common sense to me.

Not all creatures have clotting blood. Incredulity does not make for a good argument.

enjoy.
lots of precursors to the mammalian blood clotting protein cascade. lots of genetic evidence of co-option, gene duplication and point mutation.
good system to study carefully.

very bad system to point to if you are YEC. or ID.
Behe did in _Darwin's Black Box_ and as a result the scientific data has blossomed....

you do have to judge what you read. *grin*
read doolittle himself at:
http://bostonreview.net/br22.1/doolittle.html

he is probably the best researcher in the field.
i'm a bit prejudiced about him however, a talk with him convinced me to quit grad school and go to seminary....

prejudiced ? I think you mean "biased"

btw anyone notice that Chris posting at the beginning of this thread now has an atheist icon?

Huh, that's pretty interesting. He sounded like a pretty staunch creationist back then, too.
