@DreadPirateEsk @KatyMontgomerie First: https://t.co/08gonmS3df gives a good definition. 2: the application of the definition is consistent, verifiable, and repeatable. 3: lets stop using individuals with DSDs as a tool. They are either male or female.

@pascualita420 @Paul_Ilett It is. There are two sexes in all anisogamous species. (This also includes people with DSDs, as they are still either male or female, never a 3rd sex) If you want to read more about the billion+ year evolution of the two sexes:
