Prompt Human babies of low weight lose body heat quickly, and are more likely than other babies to get ill from infectious diseases. Babies of large body weight are more difficult to deliver via the pelvis, resulting in a higher rate of death in childbirth. Research indicates that babies of “medium weight” have the lowest rate of mortality, and there is a strong selective pressure favoring “medium weight” babies. Questions Which micro-evolutionary mechanism applies in this case? Why?
