Thanks for the pings as always.

Some state that "99% of mutations are harmful"
Y'all are much more up to speed on this point.

I can give one example of where a 'harmful' mutation, was of a benefit. Sickle cell anemia. In the old areas of malaria, the mutation allowed the mutants to survive longer than the non-mutants who had no resistance to it. In the short term, it conferred a great benefit, in todays world, it is a miserable affliction. I thought Tay-sachs had something similar to it. What about Lactose-intolerance?

Any clues are appreciated!
