Van Valen (1973) characterized evolution as the control of development by ecology. Sex
determination in fishes provides some clear examples of this “control” in operation. Teleost …

The optimal regulation of vertebrate sexual development and reproductive function involves
integration of internal physiological signals, indicative of an individual's sexual status and …

A masterful guide to human development that redefines the nature versus nurture debate A
much-needed antidote to genetic determinism, The Dependent Gene reveals how all traits …

A general problem in evolutionary biology is that quantitative tests of theory usually require a
detailed knowledge of the underlying trade‐offs, which can be very hard to measure …

Traditional sex-change theory cannot explain the existence of protogynous species in which
the largest females do not change sex when provided an opportunity. We present an …

The colors of 51 species of Hawaiian reef fish have been measured using a spectrometer
and therefore can be described in objective terms that are not influenced by the human …

Fishes are by far the most diverse group of vertebrates. This fact is in no way, however,
reflected in their use as model organisms for understanding sexual selection or parental …

In many species of animals, males may achieve reproductive success via one of several
alternative reproductive tactics. Over the past decade or so, there has been a concerted …

Social control of sex change occurs in a variety of hermaphroditic fishes; upon removal of
the dominant individual, the largest individual of the opposite sex typically changes sex and …

Protogynous hermaphroditism, female-to-male sex change, is well known among reef fishes
where large males monopolize harems of females. When the dominant male disappears …
