Why is human childbirth so dangerous and inefficient?

Question

I hear of women in my community and across the world either having stillbirths or dying during the process of birth all the time. Why?

How can a dog or a cow give birth in the dirt and turn out fine, but if humans did the same, the mom/infant have a higher chance of dying? How can baby mice, who are similar to human babies (naked, gross, blind), survive the “newborn phase”?

And why are babies so big but useless? I understand that babies have evolved to have a soft skull to accommodate their big brain, but why don’t they have the strength to keep their head up?

Answer 1

95% of all births have no complications. There is a reason for that there are 8.1 billion people on the planet.
