Länk - John Hawks om spelteori & informationsteori, variation i fenotyper
Surely, it seems that the way to adapt to a more variable environment is with a variable phenotype? Indeed, not so. Phenotypic variation is just as likely to make an organism less adapted to a varying environment as more adapted. This is worse than a wash if the environment is unpredictable. The best that selection can do in an unpredictable environment is to minimize heritable (i.e., the genetic component of) phenotypic variation. This is purely a loss-cutting measure, since in generations where the environment is very different from the maximally adapted value, the population fitness will tank.
