Not that it's significantly better, but there are 5 women, not 3: April Greiman, Jane Metcalfe, Noemi Trainor, Es Devlin, and Dr. Pardis Sabeti. However, they did choose Rosetto instead of Metcalfe for 1997's main photo, so there's a case to be made for 4 (though Metcalfe is in the photos when you scroll down).
