@Corrupted_Eden @0fficialW @Rap But - as a pretty decent guy; I am happy to help you on your journey of learning about how sex has evolved and how human sex is differentiated. Two interesting papers that I strongly recommend you spend time reading. https

@JustYur45919312 @Stonks_Mayne @deplorable_diva @amazingatheist You clearly don’t have a good understanding of the concept of ‘sex’ as it applies in this context. Because if we’re not talking about biology, then what ARE we talking about?? https://t.co/JLC
@beowulf1331 @WinnowingWind @us_sean @Vipergal7 @joe_nca @Elios0 @andyhartzler @HoughtonUniv Sex is a categorical dichotomy of male and female based on the billion-year old reproductive strategy of anisogamy. In that time, only two sexes have ever evolve

@parsonsj @AraquelBloss @Do_the_reading @SEBiBow @ConanLogic @jack_turban Well we can always rely on what biologists tell us. The two sexes emerge as a direct consequence of anisogamy and gonochorism. So, a male orgamism has developed along the evolved p
@kungfuhobbit The reality is that sex is a billion year old reproduction mechanisms that arose from anisogamy. This has been stable for all that deep time - no new sexes - no continuum of sex. We know why that is too... 6/x https://t.co/3GsgARBPd6

@EnbyCalledRenby @herefortoday_ @faoi @Mayhem5OO @ElleDalmayne It's gametes, Ren. There are exactly two types of gametes in each anisogamous species. Being infertile is not a third gamete type, nor does it impact your sex. https://t.co/O3icoMDYIg
