Evolution


steph_86 Wrote:But a more serious problem, resides with the issue of Original Sin. It is said that, death entered the world through the sin of the First Parents. Literally, their sin threw the whole order of creation into disarray and disturbed the natural equilibrium thus introducing death and discord in natural creation. If evolution did occur as stipulated, there is a serious problem involved. Indeed, evolution is as defined, an unguided process which through the concourse of chance produced the different forms of life out of non-living water. Because the process is unguided, there is enormous trial and error involved in the process. This of course, is Darwinian evolution as defined in current thinking. If we speak of theistic evolution, there still remains the issue of explaining how it is that death could have existed in a perfect universe before the appearance of man. Evolution, requires that the different forms of life go through successive forms which are always more adapted to their natural environment. For this reason, it puts into question the whole edifice of God's benevolence and perfection in his creation of the world. If evolution did occur, it involves that, the world as it came into being was not perfect. And this, seriously refutes the idea that imperfection entered creation through the Sin of the Origins.


There was a thread a while back that touched on this  ...  I think the consensus was that, prior to the Fall, non-human life like animal and plants did not share in the immortality enjoyed by Adam and Eve.  So death entering the world with Original Sin refers to the consequences for our first parents and their descendants rather than nature as a whole.  If this is right, it might not be impossible to reconcile a succession of pre-human life-forms with divine providence.

What I find hard to swallow about evolution is how natural selection can produce very complex biological structures.  In his book The Blind Watchmaker, Richard Dawkins attempts to account for the evolution of the eye by arguing that any complex organ can evolve provided there is sufficient time for a sufficient number of sufficiently small mutational changes to occur.

Dawkins' logic seems watertight but I have a hard time grasping how this abstract theoretical model works in practice. Dawkins emphasizes that the mutational changes must each be infinitesimal. They would presumably have to be if the emergence of the biological structure in question is not to be derailed, if it is to continuously develop as a fully-functioning complex organ. But how can such infinitesimal mutations provide a significant advantage in terms of natural selection?  Obviously eye x 0.5 is better than eye x 0. And I can accept that eye x 0.75 could provide a significant evolutionary advantage over eye x 0.5. What I don't see is how eye x 0.500000000000000000000000000001 provides a significant advantage over eye x 0.5.

In principle this applies to the evolution of any organ (although presumably the more complex the organ, the more miniscule the mutations must be that lead up to it.)  Take the textbook example familiar to every schoolboy -- the giraffe's neck. The current scientific consensus is that modern giraffes evolved from animals with much shorter necks.  What degree of neck elongation can reasonably be expected from a single chance mutation? A few millimetres? Centimetres? If it s no more than that, what immediate survival benefit would it provide?
