Cesarean Births Could Be Affecting Human Evolution, Study Says (bbc.com)
CanadianRealist writes: Larger babies delivered by cesarean section may be affecting human evolution. Researchers estimate cases where the baby cannot fit down the birth canal have increased from 30 in 1,000 in the 1960s to 36 in 1,000 births today, [according to estimates from researchers at the University of Vienna in Austria.] Science Alert reports: "In the past, larger babies and mothers with narrow pelvis sizes might both have died in labour. Thanks to C-sections, that's now a lot less likely, but it also means that those 'at risk' genes from mothers with narrow pelvises are being carried into future generations. More detailed studies would be required to actually confirm the link between C-sections and evolution, as all we have now is a hypothesis based on the birth data." Agreed, more studies required part. Cesareans may simply be becoming more common with "too large" defined as cesarean seems like a better idea. It's reasonable to pose the question based simply on an understanding of evolution. Like it's reasonable to conjecture that length of human pregnancy is a compromise between further development in utero, and chance of mother and baby surviving the delivery.
Yes. A study done at the University of Dublin concluded that if your parents didn't have any children you probably won't either.

Ah no. Sorry. Cuba in fact has more doctors. Cuba is a doctor factory - they literally export them all over the world. Greece is up there, but lags behind several countries.
Why? Are you scared of becoming a big baby?
You just came here to brag that you've sampled a statistically significant number of women.

Clearly, 120% of a number is not a 20% increase.

I agree. Unwashed lettuce can give you worms, and raw eggs can carry salmonella.

Caesars carry risks.
Especially if you're a Gaul, or believe in Rome remaining a republic.

Q: What's the easiest way to tell if someone is a vegan?
A: Just wait, they'll tell you.
Some breeds of dogs, bulldogs maybe?, HAVE to be born via C-section. The puppies can no longer fit the natural way.
And now some women have to have children born via C-Section. I think this is proof that bestiality is on the rise.

Trump was in the white house a few weeks ago and he did shake Obama's hand. Coincidence? I think not.
