Could this intricate,
interdependent system of irreducible
complexity have originated step by step? Can evolution be applied here?
Can it be really be applied anywhere? Yes it can. Here.

All the components of the

successful blood clotting needed when you cut yourself. Blood coagulation

of the staggering complexity underlying even apparently simple bodily processes.

of inborn computers have been programmed by the Creator to regulate
all these functions.
The entire system involves
parts which activate other needed components in the process of clotting.
The entire system is aware of what every part of it is doing at any one
moment. Much more complicated procedures occur utilizing
some twenty five odd
processes and proteins and are described in Michael Behe's book Darwin's
Black Box on pages 82-89.

Others like the sea

There is no evidence in hemoglobin

complex designed system, although the function of the individual components
is remarkable. The hemoglobin molecule

links and 10,000 atoms.
Hemoglobin is made when a large number of proteins
called amino acids agglomerate.
For each red blood cell, there are 280,000,000 hemoglobin molecules. Why
not just 2? Why not 500,000,000? Who designed it to be the way that it
is? There is precision in the invisible patterns behind the scenes.
Did blood coagulation evolve
according to Darwinian theory? Those who know more about blood clotting
than anyone else on Earth are professional scientists and doctors who work
on specs of blood clotting. Their journal is.Thrombosis
and Haemostasis. Professor of Biochemistry, Russel
Doolittle, at the Center for Molecular Genetics, University of California,
San Diego, asks:."How
in the world did this complex and delicately balanced process evolve? The
