If macro-evolution is a fact, then we should find the precursors
for our organs within our alleged ancestry, related species, and not in
totally unrelated ones. If instead, the species of the various phyla reflect
the hand of an intelligent Designer, we might instead find these traits spread
out among the various living things as unconnected patterns in a patchwork
quilt.
Instead, we find common traits and organs within unrelated phyla. Interestingly, evolutionists have a term for this commonly
found un-associated mosaic of traits - "convergent evolution." Paleobiologist and
evolutionist, Simon Conway Morris, reflects on one example:
·
The idea is this: that convergence – the
tendency of very different organisms to evolve similar solutions to biological
problems – is not just part of evolution, but a driving force. To say this is
an unconventional view would be something of an understatement. To start with
an example of convergence (itself an astonishing phenomenon), take the “camera
eye” – an eye comprising a lens suspended between two fluid-filled chambers,
and the kind of eye which you are using to read this feature…If you go to the
octopus and, if you’re not too squeamish, dissect it, you’ll find that it has a
camera eye which is remarkably similar to our own. And yet we know that the
octopus belongs to an invertebrate group called the cephalopod mollusks,
evolutionarily very distant indeed from the chordates to which we belong. Cambridge
Alumni Magazine (#65 Lent, p. 32)
·
The common ancient ancestor of mollusks and
chordates could not possibly have possessed a camera eye, so quite clearly they
have evolved independently. The solution has been arrived at by completely
different routes.
How is it that we and the Octopus share the same eye? Convergent
evolution! How does this explain the existence of this strange relatedness? It
doesn’t – not at all! It merely suggests that there must be some undiscovered
force that causes nature to replicate itself in entirely different species on
many occasions – a “driving force” that directs mindless evolutionary processes
to find the identical adaptive solutions. Sounds like design to me!
Morris concludes that the evidences of “convergent evolution”
require a radical rewriting of evolution. However, he doesn’t see an
intelligent Designer as a necessary ingredient. Nevertheless, he clandestinely offers an alternative "designer" - a "driving force."
