Human Childbirth Is Not Uniquely Difficult Among Mammals

Human childbirth is commonly viewed as uniquely difficult and dangerous. The reason: the combination of bipedalism and large brains creates a tight fit between the baby and the birth canal. Research at the University of Vienna has now shown that many other mammals - from domestic livestock to wild species - face similar birth problems and mortality. In some species, these complications even occur as often as in some human populations, such as hunter-gatherers without modern medical care. The findings suggest that difficult childbirth is not uniquely human. The study was published in Biological Reviews.
