KC- did you go to work or are you reading the book looking for "simultaneous mutations"?
I looked and can't find it.


ID Guy should check out page 109 (my emphasis):

In order to go straight from regular hemoglobin to C-Harlem, the right mutations would have to show up simultaneously in positions 6 and 73 of the beta chain of hemoglobin. Why is that so hard? Switching those two amino acids at the same time would be very difficult for teh same reason that developing resistance to cocktail drugs is difficult for malaria– teh odds aghainst getting two needed steps at once are the multiple of th eodds for each step haeppening on its own.
