A very interesting paper by Peter Godfrey-Smith argues yes…
Here is a selection from the article for those who may not want to read its entirety.
I will give a very simple example (similar to one found in Dawkin’s The Blind Watchmaker). Suppose we are explaining the evolution of the human eye. Building the genetic basis of the human eye involved bringing together many genes. Consider a collection of genetic material, Y, that has everything needed, as far as genes go, to make a human eye, except for one final mutation. So this background Y is such that if new mutation M arises against Y, it will finalize the evolution of the human eye. Initially, Y was rare in the population — it was the product of a single mutational event that produced Y from yet another precursor, X. Selection can make the appearance of the eye more likely by making Y more common. This increases the number of independent “slots” in which a single key mutational event will give us the eye. If the intermediate Y remains rare in the population, then additional mutations are much less likely to produce the human eye, because the right mutation has to occur in exactly the right place – in an lineage where Y is present.
I hope a discussion on the nature of evolution is pursued following this post.
