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?

So I should make a new thread for my new questions?
Not all creatures have clotting blood. Incredulity does not make for a good argument.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.
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).

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*
thanks for the link, and your commentsyou 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....

Huh, that's pretty interesting. He sounded like a pretty staunch creationist back then, too.btw anyone notice that Chris posting at the beginning of this thread now has an atheist icon?
