Temperature-dependent sex determination (TSD) is widespread in reptiles but its adaptive significance remains controversial. The most plausible theoretical models for the evolution of TSD rely upon differential fitness of male and female offspring incubated under different thermal regimes. Several mechanisms might generate these fitness differentials, and recent work provides empirical support for some of them.
