Cesarean section (surgical removal of a neonate through the maternal abdominal and uterine walls)... more Cesarean section (surgical removal of a neonate through the maternal abdominal and uterine walls) can be a life-saving medical intervention for both mothers and their newborns when vaginal delivery through the birth canal is impossible or dangerous. In recent years however, the rates of cesarean sections have increased in many countries far beyond the level of 10-15% recommended as optimal by the World Health Organization. These 'excess' cesarean sections carry a number of risks to both mothers and infants including complication from surgery for the mother and respiratory and immunological problems later in life for the infants. We argue that an evolutionary perspective on human childbirth suggests that many of these 'unnecessary' cesarean sections could be avoided if we considered the emotionally supportive social context in which childbirth has taken place for hundreds of thousands or perhaps even millions of years of human evolution. The insight that human childbirth is usually a cooperative, even social event in which women are attended by familiar, supportive family and friends suggests that the harsh clinical environment in which women often give birth in the developed world is not the best setting for dealing with the strong emotional forces that usually accompany labor and delivery. We argue that providing a secure, supportive environment for laboring mothers can reduce the rate of 'unnecessary' surgical deliveries.

This book deals with the evolution of modern humans from an archaic ancestor and the differentiation of modern populations from each other. The first section of the book investigates whether modern populations arose from regional archaeic hominin groups that were already different from each other, and argues that, in fact, most lines of evidence support a single, recent origin of modern humans in Africa. The book then goes on to examine ways in which this diversification could have occurred, given what we know from fossils, archaeological remains and the relationships of existing populations today.

The fatness effect, manifest in all six Central American countries, tends to be higher in females than in males and bears a hierarchical relationship to the extent of impoverishment and undernutrition among the countries considered. The effect of fatness level on size attainment is parallelled by hematologic measures, serum and urinary vitamins and serum cholesterol, indicating a nutritional origin rather than energy balance alone.

If confounding variables such as maternal weight and pregnancy weight gains are factored out, the apparent effects of cigarette smoking alone are reduced by no more than 17 %. New values for birthweights of the progency of nonsmoking mothers still reveal a difference between blacks and whites of 267 gm for boys and 261 gm for girls.
