Green sea turtles do not develop into males or females due to sex chromosomes, like humans and most other mammals do. Instead, the temperature outside a turtle egg influences the sex of the growing embryo. And this unusual biological quirk, scientists say, endangers their future in a warmer world.

Already, some sea turtle populations are so skewed by heat that the young reptiles are almost entirely female, according to a new report in the journal Current Biology.
