Conventional wisdom says that people deficient in one sense--such as vision 
or hearing--often acquire heightened acuity in another. These adjustments, of 
course, take place over the lifetime of an individual. Now it appears, however, 
that similar adjustments may occur over evolutionary time. Yoav Gilad and his 
colleagues at the Max Planck Institute for Evolutionary Anthology in Germany 
and the Weizmann Institute in Israel have found a correlation between the loss 
of olfactory receptor (OR) genes, which are the molecular basis for the sense 
of smell, and the acquisition of full trichromatic color vision in primates.
