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.
Consider that a square inch
of human hair contains over 20 feet.(6
meters).of
blood
vessels, the same length of one's small
intestine.
All the components of the
blood system had to appear at the same time or this complex system comprising
various mechanisms just would not fulfil the necessary requirements for
successful blood clotting needed when you cut yourself. Blood coagulation
is a paradigm
of the staggering complexity underlying even apparently simple bodily processes.
In addition, mtDNA
gives us added information.
One blood component, fibrinogen.(a
protein which
converts to fibrin
by the workings of thrombin
when ionized.calcium
is present).is
a composite
of six
protein chains, containing twin pairs of three different proteins.
Electron
microscopy has shown it resembles a barbell with an extra set of weights
in the middle. When a cut occurs, thrombin.(another
protein).alters
to slice off.(called
a protease).several
small pieces from two of the three protein chains in fibrinogen. Large
numbers of fibrin.(the
trimmed protein).form
an aggregation.
The protein doing the slicing operates.only
long enough as is necessary, otherwise the whole blood system would
clot. Another organism controls the thrombin. Millions
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.
Why, if evolution be true,
is there two different clotting systems?
Vertebrates,
crustaceans.(crustaceans
are invertebrates
like shrimp, crabs, lobsters,
having a hard outer shell).and
other arthropods
have a protein
based clotting system.
Others like the sea
urchins, worms, etc., have a very low vascular
pressure and can seal any leak with their white
blood cells. It's a slower system for a slower species.
Hemoglobin:
There is no evidence in hemoglobin
alone of an irreducibly
complex designed system, although the function of the individual components
is remarkable. The hemoglobin molecule
is comprised
of 574 amino acid
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
paradox
was, if each protein depends on activity by another, how could the system
have ever arisen? Of what use would any part of the scheme be without the
whole
ensemble?"
Cells contain information
for building several different types of hemoglobin. For example, one is
optimized for carrying
oxygen in
the blood of adults, but yet another is found in the
fetus
which has a greater affinity
for
oxygen capture
from the mother's blood. Both are perfected for their unique functions.
Hemoglobin has 4 component
proteins.(2
sets of 2 different types).sticking
to each other. Hemoglobin binds oxygen.(like
you would catch a football and hold it, running with it, later releasing
it when you've reached your destination, a touchdown).in
a manner which is able to fully saturate in areas such as the lungs, yet
releases oxygen when needed by peripheral tissues.(an
amazing process); however unlike the.extremely.complex
AMP
system, the interaction does nothing beyond the functioning of the individual
components.
Among animals, hemoglobin
has many differences and many similarities when compared with human hemoglobin.
Do these similar sequences support descent from a common ancestor? If you
concur,
then the question to answer is how comparing shows how a complex biological
system achieved its function.
TPA:.The
chance by evolution, that random duplication and recombination of thirty
thousand gene
pieces could produce the four different types of TPA.(Tissue
Plasminogn Activator).clotting
proteins
appearing one after the other, is approximately 1/1018.(one
tenth to the eighteenth power).
With these odds, if a million people played the lottery year after year
it would take about one thousand billion years before anyone.(not
just a particular person).won
the lottery. One thousand billion years is roughly one hundred times the
current estimated age of the Universe. In other words, it is impossible
evolution.(if
it were true).could
be involved at all. Evolution deals in chances. But, evolution has.absolutely
no chance at all!
