@SamuelHamerIOM Each sex is defined with respect to a gamete type. This paper on the evolution of sex explains why there are two sexes and what is distinct about each sex. https://t.co/3GsgARBPd6

Trans folks are getting it slowly that sex is indeed binary. Watch their next move: rewriting the history of biological research, claiming that the gamete argument was invented post 2018 to spite trans people 😳 @EU_ScienceGeek

No, this has been the definition for woman, or an adult human female since we understood humans had gametes and their role. Do not even try to pull this recreation of history. Woman has always been adult human female, and females have been linked to ova.
