Theory In Crisis: Iii
If you feel we evolve by chance,
here’s something that you must decide:
the type of steps that you will dance
explaining how blood cells divide.
Now only mammals do this split
which seems odd on the face of it.
For surely wings need oxygen
in the same way; where to begin?
See, mammals have erythrocytes
That have to squeeze in places tight.
Apparently, they found it scary
traveling the capillaries.
And so, it’s said, mutation error
found a way to meet this terror:
eject the red cell nucleus
and slide on through without the fuss.
Capillaries in a mammal:
needle’s eye through which a camel
passes, so the logic jumps:
just remove those great big humps!
And so is formed an apparatus
in an instant, all for gratis.
But wait! No, Darwin’s change evolves
through incremental change, resolves.
First the stem cells must divide
since capillaries are too wide.
Then, as we’ve discussed,
they must pinch off the nucleus.
To do this, cells must build a ring
That somehow pushes everything
within the cell all to one side,
constricting forces, slow applied.
A soft spot in the wall then sprouts;
the nucleus gets pushed right out.
Pinched out just like a bit of dough:
it takes ten minutes, rather slow.
From here, it seems, we pick the best:
enucleated blood cell test.
There cannot be an in-between,
emerging slowly on the scene.
It must appear in one fell swoop
for Darwin filters out the soup,
discarding any useless bits,
unfinished intermediates.
The magnitude of change required:
too great for chance; time has expired.
This leads some learned folk to say
it must have been designed this way.
