In article number 2000050, Barbora Straková et al. speculate that environmental sex determination in amniotes evolves via a heterochronic shift of sex change from the adult to the embryonic stage in a hermaphroditic ancestor. Subsequently, the loss of responsiveness to environmental stimuli (stress) led to genotypic sex determination, where the sex is decided at conception. Cover image by Tereza Unzeitigova.
