THE
LONG AND THE LONG OF IT
My boys and I have a
running joke. Whenever we see an obvious display of God’s
beauty, power, design or sense of humor in the world around us, we
nudge each other and say: “It sure was lucky that this thing
developed by pure chance over billions of years!” “It
sure was lucky that over bazillions of years the salmon developed
the ability to alter its entire metabolism from
freshwater-friendly to saltwater-friendly and back again, and then
to be able to find its way back upstream to its original
birthplace (sometimes hundreds of miles) to spawn!” Yup;
sure was lucky.
Consider the giraffe. A
mature bull giraffe is about 18 feet tall (the tallest on record
was George, at the Chester Zoo in England. He was 20 feet tall).
As you know, much of that height is in his neck. Because of the
pressure required to pump blood all the way up that thin neck to
the brain, the giraffe needs a tremendously powerful heart, and
his heart can be as much as 2 _ feet long (yours is roughly the
size of your fist!). Sure is lucky that he has that huge heart!
There’s a little
potential problem, though, every time he goes to take a drink.
When the giraffe lowers his head that big heart is no longer
working against gravity, it’s working WITH it, and so the
mighty heart pump will literally blow the giraffe’s brains
out as he is trying to get his drink. What a bummer! Animals with
blown-up brains don’t last long, so there go all the
giraffes.
But wait! The arteries
up the neck are equipped with a series of check-valves that close
as the giraffe lowers his head, shutting down the blood flow to
the brain. Sure is lucky he has that! Even at that, the pressure
remaining after the last check-valve is still enough to burst the
small vessels in the brain. Poor giraffe!
But wait! At the base of
the brain is spongy tissue which absorbs that last rush of blood
so that the brain is safe. Sure is lucky he developed that! But
another problem arises - so to speak – when the giraffe
lifts his head back up from his drink. Now the blood all rushes
AWAY from the brain, causing the giraffe to pass out cold and
collapse. Now he is easily eaten by any passing predator, and the
African plains are loaded with those. Eaten animals can’t
propagate their species, so there go all the giraffes again. Rats!
But wait! The veins
going down the neck also have a series of check-valves which close
down the blood flow away from the brain. Then that spongy tissue
at the base of the brain squeezes the absorbed blood into the
brain as the system is equalizing again, so the giraffe is up and
running (literally) without skipping a beat (literally). Sure is
lucky he has those features, huh?
The real point here is
that any one of these features – by itself – is
actually detrimental to the giraffe’s survival. Together,
however, they form a perfectly designed system that allows
giraffes to thrive and survive. But they would have to be in place
simultaneously, functioning together, or the giraffe could never
have survived. A slow, gradual process could never allow giraffes
to make it, because ALL of the parts must be working together FROM
THE START, or the animal is dead.
Statisticians have
clearly shown that the complexity of life could NEVER arise by
pure chance/evolutionary processes. How much greater the
impossibility of giant-sized hearts, artery check-valves, spongy
brain base, and vein check-valves all having spontaneously (and
simultaneously) developed by luck!
That’s not lucky,
that’s miraculous. But a miracle demands a Miracle-Worker.
Do you know Him? Do you belong to Him? He calls out to us through
His Creation. He instructs us through the Bible. Keep your eyes,
ears and heart open to Him. After all, you don’t want to
leave your eternity to chance! See ya next week.
