Reply to comment by ElizabethHiems in TIL, the placenta that forms with a fetus isn't created by the mother. It grows from the fertilized egg and some fetuses actually develop outside the uterus attached to the intestines in the body cavity. by darw1nf1sh
There is no tiny uterus if the fetus is formed outside of it. The hormones can kick in and cause contractions but the baby needs to be removed by c section, as you said.

I (gently) threw my puppy into a mound of pillows for years.
Still no Krypto.

Wkipedia is wrong. A five minute google search shows that Roman Palaces sometimes had corridors with doorways coming off them.

How exactly would labour start? Did the oxytocin receptors form on the tiny uterus? Is the lower segment there? If a baby grows in your abdomen then you don’t deliver by caesarean and you won’t go into labour.

Reply to TIL in 1979, in between a double-header, the White Sox exploded a crate filled with disco records to stands of over 50k disco haters. Thousands flocked to the field afterward, which became so destroyed that they forfeit the 2nd game to the Tigers - the last time in AL history. by JackMacWindowsLinux
It's okay that disco left the mainstream because Frankie Knuckles just took out some of the lyrics at a place he DJ'd in Chicago called the wareHouse and people are to this day still listening to that type of music, it's known by the name House Music.

Yes, there would be a risk of defects in wanted pregnancies, in contraceptive failures or sexual assault. As for anatomy during pregnancy, the mothers body DOES see the fetal placenta as foreign, which is why the immune system is suppressed by various mechanisms during pregnancy, so thar her body doesn't attack the fetus. My background is biochemistry and embryology so I DO know a lot about anatomy and maternal vs fetal behavior. The most practical and kind approach would be for anti choice people to not interfere in things they know nothing about. Let the doctor and the woman make decisions about her life and body.

You are implying that men and women are different species

Reply to comment by marmorset in TIL The Dick Van Dyke Show was originally written entirely by Carl Reiner, about stories from Reiner's life, and starred Carl Reiner. The pilot was unsuccessful so it was reworked with Dick Van Dyke playing Robert Petrie. by jamescookenotthatone
And I'm sure Molly Goldberg predates them all.

Ah one of the things that makes me happy is knowing that we know a tiny portion of what’s really going on .

I was taught it is because the Y chromosome sperm are slightly lighter, therefore swim faster and have a higher chance of fertilizing the egg.

He also had important lessons on how landlords are terrible and the KKK was a terrorist organization to be opposed.

No it specifies vertebrae. The vertebrae in our spines have a second set of jaws apparently.

I woulda thought opposite. Cause a species could use more females than males.
Another comment said, for fertilization, it's about equal.

Men universally have a shorter life span than women.
This is due to a number of factors, not least that males make a lot of dumb decisions.
The fact that men are the dominant species may explain the current state of the planet.
I could be wrong, but as a male, I think I'm right.

Sex and gender are different things. Not a fan of inventing new genders every Tuesday though
