interesting! do you know the allele that causes sickle cell anemia is an adaptation to fighting malaria? 2 alleles give you sickle cell anemia having just one offers you malarial prevention.

Did you know, that if you take
every single person killed in a
terrorist act around the world in
the last twenty years, and you
add to that all the lives lost in
the Middle East since 1967 --
the 6 Day War -- and you add to
that every single American life
lost in Vietnam, in Korea, and in
every single American
engagement since then -- Iraq,
Afghanistan... If you take all
those lives and you multiply by
two, that's the number of
children that die of malaria every
single year. 90% of those deaths are in subsaharan africa.
