Here, we review recent empirical advances that have improved our understanding of why
and when sex change occurs. We show that sex-changing animals use a greater diversity of …

Application of optimality theory to the evolution of life histories has been broadly successful
in predicting the conditions favoring sex change, the type of change, and the timing of such …

Preface xii an individual can be both a functional male and a female at the same time. In
some of these simultaneous hermaphrodites, an individual may alternate between male and …

The size-advantage model asserts that mating behavior influences the incidence and
direction of sex change in animals. Selection for protogyny (female to male sex change) …
