81. Higher mortality rates could be construed as such

But in terms of child-birth, the "selection" happens after the mother proves to be viable and is not dependent on the viability of the offspring. According to the study I posted, the responsible variable was most often nutrition, rather than genetics.

In some ways, our civilized society is instead selecting people who are maybe more tolerant of nutritional deficiencies or infections that are only prevalent in civilization; while these traits may sound important, in nature, they may of been widely ignored (as deficiencies and infectious bacteria was far less common) and instead the "strongest" were the fastest, smartest or hardiest of the bunch would be selected. Post-foraging man has threw natural selection in a bit of tailspin (which isn't good if we will one day head back into nature).

Other mortality rates do play important roles in selection, as well as population control among foraging groups. Another behavior of foragers that promotes population control is breast-feeding as well, which can typically reduce fertility of nursing mothers.
