(This is an edited text of a note I sent to Dr. Edward Feser, author of the book
Aristotle's Revenge.)
Biology has no
explanation for speciation, and the problem of explaining evolution is an
insuperable one for biology.
The very
existence of an empirical science of genetics condemns Darwinism. That
genetics can be an empirical science with predictive powers requires a high
degree of faithfulness in the transmission of genetic information from one
generation to the next. Geneticists would be astonished and alarmed if a
flock of chickens bred to produce white eggs would have one hen that faithfully
produced a purple one. (Long story, the hen that produced them was
genetically of the grandparent generation.) A biologist would be shocked
if an egg produced by a chicken hatched an eagle. All the dog breeding
experiments over hundreds of years have only ever produced dogs, never a cat or
even a wolf. The teleology all points to faithful reproduction.
Then there
is the problem of directedness of evolution. Why only upward and why only
occasionally? Why aren’t apes spontaneously and to this day
occasionally giving birth to proto-humans? It was started once, a few
million years ago and never done since - why? (Was it a miracle?) There
have been over 7 billion humans born since 1900, so why have we not seen either
a higher state human or a retrocession into a more primitive type like Peking
man?
Even with
simple life like viruses, we hear of new strains of influenza – but these still
produce influence, not meningitis.
The
principle of biology that “like begets like” seems to hold – like a principle
of science! There seems no room for evolution in the manner of genetic
mechanics. All the teleology points to faithful transmission of genetic
information from one generation to the next.
A problem
for philosophy is to identify the thing in which the evolutionary change
occurs: not in the parents, and the offspring is what it is from the moment it
comes to be. So, it can’t be said to be the offspring that changed. (The
offspring is a different substance from the parents) And it can’t be the
species because a species exists in its membership. So there is a problem
identifying in exactly what evolutionary change occurs.
In his
book, The Difference of Man and the Difference It Makes, Mortimer J.
Adler goes through all the philosophical failings of biology in trying to
explain how rational man could evolve from non-rational, primitive apes.
It’s a
wonder how Darwinism even persists as a theory apart from the atheism it seems
to support. Although Aquinas allowed for evolution, I think all we have
that’s tenable is a theist theory. The teleology points to faithful
transmission of information and it would take some kind of external
(miraculous, since it occurs only once) intervention to change the course of
natural teleology.
P.S. I’m open to biology
solving its problems without recourse to theism, but as a chemist I get some
satisfaction at watching Darwinists sputter when challenged. They seem to
know it’s B.S., but it’s all they’ve got.
