@Blow_The_Trap Was it this point? https://t.co/Y85ds5szAi In that case, here is a paper describing why two and only two sexes have evolved. https://t.co/3GsgARBPd6
@JustinFREAKINS My sources are the peer reviewed research literature on the evolution of sex. You refuse to engage with the literature when asked if you think the biologists are wrong? https://t.co/3GsgARBPd6
@JustinFREAKINS Do you think these biologist are wrong that only two sexes have evolved based on the two different gamete types? https://t.co/3GsgARBPd6
@JustinFREAKINS Do you disagree with these biologists that only two sexes have evolved based on the two gamete types? https://t.co/3GsgARBPd6
@JustinFREAKINS Sex is defined with respect to gamete types. It is discrete. This is foundational biology. To argue anything else requires some very explicit argument. You cannto show this. Here is just one paper that explains why only two sexes have evo
@KaylinStuff @TheRavey @FondOfBeetles Could you please link me to some of these papers? Biological study demonstrates the firm binary nature of sex. https://t.co/b6Ip6hFpC0 https://t.co/J3v8PTdjDM
@hydropsyche1 @kayleigh_elt @AlphavilleXpres @celestelabedz @NSF Biologists don't make foolish statements about sex being a spectrum. Biologists don't conflate the spectrum of sex characteristics with the binary of sex. https://t.co/HHnlggsj3o

@TheTransJourno @Wommando Yes there is. Having the body type which, barring disease or developmental disorder, produces large sessile, not small motile, gametes. It’s the same in anisogamous species across living organisms. https://t.co/RNlRJz7IyJ

@PStormhuntress @HermioneG_GCF @NihilisticNacho @peacelove1967 @keffals @jk_rowling If you're denying this, then you are indeed pushing an ideological agenda. Every peer reviewed biology paper you can find that defines the male and/or female sex will do so
