Much medical literature attributes persistently high rates of very low birthweight (VLBW) to “dysregulated” gestation. We offer the alternative view that natural selection conserved well-regulated, though nonconscious, decisional biology that protects the reproductive fitness of women by...

Individual-level research reports that adverse environmental conditions during infancy increase the risk of mortality later in life. Extending this model to populations implies what we call the "diminished entelechy" hypothesis in which birth cohorts subjected to virulent environmental insults...

Literature describing environmental influences on human conception and gestation implies that the ratio of male to female live births should vary positively over time with the population's ability to produce and distribute goods and services. No direct test of this hypothesis appears in the...

For all climatic regions, mortality due to cold exceeds mortality due to heat. A separate line of research indicates that season of birth predicts lifespan after age 50. This and other literature implies the hypothesis that ambient temperature during gestation may influence cold-related adult...

"Relational egalitarians propose that the ideal of equality is primarily an ideal of social relations. Yet contemporary workplaces are characterized by hierarchical employer-employee relationships. This raises an urgent practical question: are the employment relationship and other workplace...
