Yes. Humans have evolved to do a lot of really cool things. But having an easy childbirth is not one of them. This is primarily for two reasons. The first reason is that we have big heads to house our big brains. The other reason is that we have relatively narrow hips. Bipedal movement requires narrower hips, so we can keep our feet underneath us. The net result is we have a big head that needs to fit through a small opening. We even evolved to give birth very early in the gestation process. If we give birth earlier the baby is smaller and less likely to kill the mother. This is one of the reasons human babies are so useless when born.
