This bee mite probably arose in the Eastern or Chinese Honey Bee population and hopped over to the United States in 1987. They quickly infested western or European honey bees.

Perhaps, then, the retina needs to be sort of rewired for the new conditions. There needs to be some plasticity so...Study in Royal Society journal on heritability of female orgasm
