Darwin first raised the question of sex ratio evolution, and saw it
as both important and enigmatic. He was, however, unable to make
much headway with the problem and declared it a puzzle for the
future. This particular future arrived about 60 years later, when
R. A. Fisher (1930) pointed out that under autosomal inheritance
half of the genes passed to zygotes in any generation come from
males and half come from females. Fisher noted that this
one-mother/one-father symmetry generates frequency dependent
natural selection on sex ratio, resulting in an evolutionary equi
librium in which half of the reproductive resources are devoted to
daughters and half to sons. Although widespread interest in sex
ratio as a phenotypic trait did not occur for another 30 years, it
is difficult for us to overestimate the impor tance of Fisher's
brief and characteristically cryptic remarks. Almost all of the
innovations in thinking about sex ratio can be viewed as
alterations of one or more implicit assumptions in Fisher's scheme.
The present book on insect sex ratios is testimony to the
fruitfulness of his original ideas and of their descendants."
