Actually, the soul evolved at the same time as a number of other measures to ensure that women's lives would suck. I have on reliable authority that
God hates women. In carefully crafting a species in which the females would have the crappiest possible existence, God came up with a number of fiendish ideas, including corsets and pumps (devices of such eldrich horror that they even cause discomfort to the more cultured males of the species, i.e. me). Sine Dubio, Deus Vult.
1 But the crafty Lord did not limit himself to mere devices to cause women's suffering, he actually placed ridiculous anatomical mistakes in the very flesh of women for the sole purpose of causing discomfort.
2 First off God ran the birth canal straight through the pelvis, and made birth the exclusive domain of women.
3 Alas, that did not cause enough pain to placate the good Lord, so in order to complicate matters further,
4God said unto the half-witted Pre-Adamites to stand on their hind legs so that they could see approaching leopards that tended to snatch the more physically frail women off in the night.
5 And there was great snickering in Heaven.
6 Still, the Lord's great misogyny was not assuaged, so the Lord contributed to the pain of women during childbirth, and to the frustration of humankind in general with his next curse.
7 And the lord said to the half-witted pre-Adamites
8"Go ye, and grow thy skull huge and thin, that they might split when whacked with a rock, and further that they might split a woman's narrow pelvis at birth!"
9 And there was much snickering in heaven, and God got out a case of cold ones.
10 And there was much domestic violence, and there was much pain of women, and this was pleasing unto the Lord.
11 Still, the great and irrational anger to women the Lord held was unquenched, and the Lord went unto his consultant Satan for ideas.
12 The Lord spake unto Satan the Consultant:
13 "Oh horned consulting one who art a ripoff of pan, how is it that I may cause further pain and gnashing of teeth among the women kind of the world?"
14 And Satan, casually reclining in his ergonomic chair replied to the Lord thus:
15: "Oh smiteful one, who art but a rip off of Zeus, there is joy enough to make a man suffer by your own hand, but there is art o make him suffer by his own. Give unto the stupid ones the capacity for religion, and they'll pretty much deal with giving themselves enough grief so you could take the days off and go golfing."
16 And the Lord did so, and gave all of the puny mortals who art the abused playthings of the Lord souls and religion, and henceforth they have adequately generated their own misery.
17 And the Lord spake unto Satan the Consultant:
18 "Thank you O horned consultant."
19 And Satan said "Pay me you cheap b*****d"
20 And at this the Lord was displeased, and told men evermore not to trust Satan the Consultant, who evermore is unemployed except in hell, which is where consultants go anyhow if they can't get good recommendations.
21 And the Lord saw that this was good, and went golfing.
