You are acting like an ignorant first rate asshole. As example of your ignorance is your lecture about the dangers of an umbilical cord wrapped around the neck. That is, in fact, very common and it is incredibly rare for it to lead to complications. https://unmhealth.org/stories/2022/12/nuchal-cord-managing-d... Which leads to your willful ignorance of the fact that the guy was exposed to a lot of research about prob…
Did you stop to consider that perhaps the reason complications are rare from the umbilical cord wrapping around the neck, is because medical professionals are actively monitoring for it and mitigating the issue?
The link that I provided explains the characteristics of the umbilical cord that have been evolved to minimize the probability of problems. It really isn't a problem. Even in childbirths where people don't worry about the umbilical cord.
This shouldn't come as a surprise. Evolution has selected for safe natural childbirth. Unfortunately in homo sapiens there is a conflict between our recent evolutionary pressure for large heads, the needs of walking, and for safety during childbirth. And so childbirth is much more dangerous for us than for other mammals.
Modern humans also have the problem of mothers in poor health. Reasons vary from drug use, to age, to sedentary lifestyles. Of these, drug use is the most dangerous. Despite most mothers not using drugs, drug use is a factor in something like half of childbirth deaths.
Then there is the list of usual complications. Breech birth, infection, blood type incompatibility, diabetes, heart attack and so on. It is a long list. It interacts with the previous lists - for example breech birth is made more dangerous because of our large heads. Complications from knotting of the umbilical cord is very far down the list of things that go wrong.
