Does temperature-dependent sex determination offer any benefits to turtles, or is it better regarded as a possibly ancestral system of sex determination that has persisted in most lineages of turtles because it works well enough?
What will be an ideal response?
The sexual dimorphism hypothesis proposes that the sex that benefits more from being large as an adult should develop at the temperatures that produce a large adult for that species. The occurrence of three patterns of temperature-dependent sex determination complicates that hypothesis, but does not falsify it. Another perspective suggests that the sex-determining effects of temperature are secondary to the effects of temperature during development on some important functional characterof the hatchlings, such as size at hatching, crawling or swimming speed, or the type of escape behavior employed by an individual, and that selection acts on those characters.
