Bigger newborn babies, statistically speaking, have a better chance of survival than tiny ones. So long as they can get out of their mothers’ bodies safely, that is! A study in Proceedings of the National Academy of Sciences suggests that the modern practice of Caesarean section is rapidly altering human evolution. Ever bigger babies carrying genes for ever smaller pelvic bones can now survive, the authors say, leading to bigger babies and more moms with small pelvic dimensions in the human population.To read the rest, click on "Are Humans Evolving Through Caesarean Sections?", written by obstetrician Dr. Elizabeth Mitchell.
An estimated three to six percent of newborns around the world cannot negotiate their way through the birth canal. This mismatch of baby’s head and mother’s pelvis is called fetopelvic disproportion, or cephalopelvic disproportion (CPD). Before the advent of safe obstetrical intervention through Caesarean section in the 20th century, CPD was often a death sentence for these babies and their mothers, and those who managed to be born with great difficulty often suffered severe damage.
