Quote by: Abdullah Yeah OK, using that logic, one could say that, since people born with genetic leg paralysis are unable to walk and so are saved from being killed in traffic accidents, therefore genetic leg paralysis is a "useful genetic feature."

Why not? If it were the case that all people with cars died in accidents, or at least most then we'd be left with mainly paralysed people to mate and pass on their mutate genes.
This is mendelian genetics, it's as basic as it gets. Evolution doesn't care whether a gene is considered useful or not, that is subjective. The selection pressures change with the environment, it is not set in stone.

Quote by: Abdullah You obviously dont know that Sickle Cell Anemia causes the oxygen-carrying capacities to be weakened due to the unsual shape. Mutations are "mistakes in the letters when copying a written text." -Pierre-Paul Grassse of the French Academy of Sciences.

Obviously, I do. I said carrier, which are those with hetereozygous mutated Haemoglobin gene. These people are weakly phenotypic of the sickle cell condition, not enough to cause major health hazard but their increased malaria resistance gives them to the edge over normal Hb carriers.

Quote by: Abdullah A good example is E.Coli, a bacterium whose mutants have been studied very carefully, countless mutations over this long period(since the Permian) have not led to any structural changes.

Tell me, is E.coli a successful organism? Is it struggling to survive in our day to day world?
