@BowsacNoodle @Fullycaffeinated AQUINAS
"With respect to the particular nature the female is something defective and occasionatum, for the active force in the male semen intends to produce a perfect likeness of itself in the male sex; but if a female should be generated, this is because of a weakness of the active force, or because of some indisposition of the material, or even because of a transmutation [brought about] by an outside influence"

Now we all know the Y chromosome was once an X Chromosome until it got hijacked by some unknown parasite that adapted it by injecting it's own material into it & dumping everything else in it couldn't use & the X Chromosome became less, it became a shell of it former self & the parasite adapted the X Chromosome to accommodate it's own descendents until they can invade a woman's body and develop inside her, feeding off all her resources .

So Aquinas is part right in his claim, but he just happen to pick the wrong sex, that's all
