Why is human childbirth so dangerous and inefficient?

1.13K viewsBiologyOther

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?

We have big heads and narrow hips

Big heads for our big brains, we can even fully develop them in utero because then our heads would be too big, that’s why our babies are so helpless.

We have narrow hips to walk bipedally. No other living specimen is bipedal and gives live birth.
