Ebook Natural Selection and the Evolution of Life Expectancy
This research advances an evolutionary growth theorythat captures the pattern of life expectancy in the process of development, shedding new light on the sources of the remarkable rise in life expectancy since the Agricultural Revolution. The theory suggests that social, economic and environmental changes, that were associated with the transition from hunter-gatherer tribes to sedentary agricultural communities, and ultimately to urban societies, affected the nature of the environmental hazards confronted by the human population, triggering an evolutionary process that had a significant impact on the non-monotonic time path of human longevity.
Moreover, the theory indicates that the deterioration in the health environment in these transitions enhanced the genetic potential for longer life expectancy, thereby providing the genetic infrastructure for the dramatic impact of recent improvements in health infrastructure on the prolongation of human life.
