@turpywurpy @NathanielHart72 @drawnoutofshape @jean_phoenix_ @FrancisHayden1 Can you find a biology paper (peer reviewed) that characterises what a sex is in your imagined way? Just for starters, here is one on the evolution of sex that defines what a sex

@PetreRaleigh Never? "Biologically, males are defined as the sex that produces the smaller gametes (e.g. sperm), implying that the male and female sexes only exist in species with gamete dimorphism (anisogamy)". https://t.co/O3icoMDYIg

@ThemBread @ThiccZelda @GlennZinny @LumiRueLuv @tedxlondon @n1kk1m Here is one such paper. Please do read. https://t.co/3GsgARBPd6

@galbenedekk @JonathasG4 @fuckhotline @notAfanOfgayPpl @SalafisUnveiled @Khalidalzarouni Peer reviewed biology is quite clear on this definition of what a sex is and research is focussed on explaining how two sexes evolved. e.g. https://t.co/3GsgARBPd6

@ElleTrudgett @dev_deets Here is a paper that uses recent modelling to explain why there are two sexes and only two sexes. Does your “model’ have any peer reviewed biology papers modelling to explain what is observed? Nope. I trust you read the paper.

@PinkRangerAnna1 @fashionfwdfello @Emmy_Zje Here is just one example of an actual peer reviewed biology paper that discusses the evolution of the two sexes. A full glossary is supplied. https://t.co/3GsgARBPd6

@TheKarotte @Ghostthatwalks9 @avegansocialist @salltweets You do not understand what a sex is. This is a biology paper on its evolution with a full glossary. https://t.co/3GsgARBPd6

Why you need any more than 2 sexes. From a logical and evolutionary perspective, it doesn't make any sense.
