In the heterozygous condition, it does offer some protection from malaria.

That may be true, but it does not address my statement above nor my other statement in the post which deals with the fact that it would be disastrous for a group that had this condition in order to survive malarial infection. It would kill 1/4 of their children. Clearly people do survive living in malarial infested areas without the benefit of this mutation. Let me also remind of why this is not the kind of mutation that would verify evolution - it adds nothing to the organism that leads to greater complexity and new functions of which there had to be tons of in order for man to have descended from bacteria.
