Note: I posted this originally in the C&E forum as the conversation that sparked the idea occurred there. But it may be more appropriate here.
The creationist notion of evolution and speciation would seem to owe a lot to the philosophy of Plato. This was brought home to me particularly in a conversation with Mark T, though he is not the only one to make similar points.
In Platos philosophy, material things lack perfect existence. They are little more than shadows of real things. (Parable of the Cave). What really exists are eternal forms. The forms are eternal, immaterial and perfect templates of which concrete material individual instances are contingent, mortal and imperfect copies. Each rabbit, each chair, each instance of the colour red is an imperfect replica of an eternal and perfect form of a rabbit, a chair, the colour red which exists beyond the material world. The form constitutes the essence (being) of everything that is, but no one material instance of a form comprises the whole essence of the form.
Now compare that with the common creationist explanation of a kind and its evolution. The original created kind (which may have been taken on to the Ark) is said to be fully-formed, perfect and to have had a genome which included all the possibilities of all subsequent variations in the combined gene pools of all species emanating from it.
Now when a part of the population of the original kind adapts to a particular environmental pressure, it can only do so by emphasizing some aspect of the genome and not expressing other parts. So it no longer expresses 100% of the kind genome. It has become an imperfect copy of the original kind.
Similarly, if speciation occurs and a part of the original kind becomes a separate species from the rest, it can only do so by losing some of the information in the original genome of the kind. By the same token, the remaining population has also lost some of the original genome---a part found in the new species, but not retained in the remaining population. So now we have two less than complete copies of the original kind.
As speciation continues, the original genome keeps splintering into smaller and smaller portions, so that each new species is based on a less complete copy of the genome which the kind began with. At some point, it must become impossible to generate a new variety or species, because there would be too little of the original genome left to support existence.
So, if one begins with a Platonic concept of a perfect ,whole kind, the only thing evolution can do is create incomplete copies of that kind---and the more variation, adaptation and speciation there is, the less complete each is in comparison to the original.
It seems to me the bible itself gives us a different image, best expressed in Jesus comment on the mustard seed: a small seed, which grows into a bush large enough for birds to nest in. How do we get a large bush from a small seed? By adding to it. It grows. It adds roots and a stem, then small branches, then branches on branches, then more branches as the earlier branches grow larger to support more new branches. Even if some branches are removed, the others keep producing.
And this is the scientific image of evolution. Not of beginning with a whole form and splintering it into varieties, but of beginning with a seed which adds structure and new branches and branches on branches and more and more branches. New species are not subtractions from an original whole; they are additions to the growing family tree. The gene pool is not divided again and again and again till it is too small to divide any more; rather each new variety adds new potential to a gene pool. And speciation creates a new gene pool---just as one can take a branch from a plant, develop new roots on it, and start a new tree. And this tree can also grow and add new possibilities to those it brought from its parent tree.
God didn't reveal himself in the beginning to one of the great Mesopotamian nations. Instead he called one person (Abraham) and grew a nation, actually several nations, from his seed to be the vehicle of his revelation. When his people needed a new king, God did not direct Samuel to a full-grown mature man to lead a rebellion against Saul, but to a boy tending the sheep and grew him into a leader. And although huge crowds followed Jesus, only a tiny group were called together to plant the seed of the church in the world and grow from there.
Evolution also proceeds from the small start of simple unicellular life and over generations adds and adds and adds new growth, new varieties, new species as living things spread out and explore and adapt to new environmental pressures. It seems to me that evolution is another expression of Gods mustard seed principle. And that if creationists abandoned their Platonic interpretation of created kinds for a biblical mustard seed interpretation, the so-called conflict of science and scripture would disappear.
