Turtle embryos play a role in determining their own sex
By moving around the egg to find what Richard Shine, a professor at Macquarie University of Australia and one of the co-authors, calls the “Goldilocks Zone”—where the temperature is not too hot and not too cold—the turtles can shield against extreme thermal conditions imposed by changing temperatures and produce a relatively balanced sex ratio. “This could explain how reptile species with temperature-dependent sex determination have managed to survive previous periods in Earth history when temperatures were far hotter than at present,” he says.
