No one is certain about why these animals developed this way over thousands of years, but they do have some guesses. Warmer, cooler weather creates female alligators. It has been proposed [24] that temperature acts on genes coding for such steroidogenic enzymesand testing of homologous GSD pathways has provided a genic starting point.
