The recent "American Scientist" just happens to be a little gold mine of relevant or semi-relevant topics to our discussions.
Another article in the Nov-Dec 2003 issue is: "Survival of the Fittest Molecule"
They are using evolutionary theory and mechanisms as a way to produce proteins useful in disease fighting. A vacine for dengue fever is one such project.
As an aside there was one bit that made me think a bit about something I didn't have clear.
"Becuase preserving a low mutation rate is important for complex organisms, the principle source of functional genetic diverisy is recombination between sister chromosomes from existing point mutations." ... "Indeed, recombination followed by natural selection is the foremost mechanism of organic evolution."
When discussing how evolution could get from one point to another I have often been a bit too focused on mutations. It is important to remember that a few mutations can be used to create a lot of genetic change through the recombination mechanism.
The method described forces muations, recombination and a selection process to get to useful protein products. Any medically useful products produced will be a direct consequence of evolutionary theory.
