A primatologist explores the mystery of the origins of human reproduction, explaining that understanding the evolutionary past can provide insight into what worked, what didn't, and what it all means for the future of mankind.
Evolutionary selection has been radically relaxed in the human species as a result of the development of civilization, science in general, and medicine in particular. While these advances have hugely benefited current populations, they have to a significant degree released the species from the biological process which created it and maintains its viability. Formerly, natural selection took place largely as a result of differential mortality, but now that most people survive well beyond their child bearing years, selection is determined largely by differential fertility. Aside from genetic illnesses, this new selection is also characterized by a negative correlation between fertility and intelligencethe core of eugenic concern for over a century. Eugenics views itself as the fourth leg of the chair of civilization, the other three being a) a thrifty expenditure of natural resources, b) mitigation of environmental pollution, and c) maintenance of a human population not exceeding the planets carrying capacity. Eugenics, which can be thought of as human ecology, is thus part and parcel of the environmental movement. Humanity is defined, not as the totality of the currently living population, but as the number of people who will potentially ever live. This is a book about the struggle for human rights and parental responsibility.
Evolution's Arrow argues that evolution is directional and progressive, and that this has major consequences for humanity. Without resort to teleology, the book demonstrates that evolution moves in the direction of producing cooperative organisations of greater scale and evolvability - evolution has organised molecular processes into cells, cells into organisms, and organisms into societies. The book founds this position on a new theory of the evolution of cooperation. It shows that self-interest at the level of the genes does not prevent cooperation from increasing as evolution unfolds. Evolution progresses by discovering ways to build cooperative organisations out of self-interested individuals. The book also shows that evolution itself has evolved. Evolution has progressively improved the ability of evolutionary mechanisms to discover effective adaptations. And it has produced new and better mechanisms. Evolution's Arrow uses this understanding of the direction of evolution to identify the next great steps in the evolution of life on earth - the steps that humanity must take if we are to continue to be successful in evolutionary terms. A key step for humanity is to increase the scale and evolvability of our societies, eventually forming a unified and cooperative society on the scale of the planet. We must also transform ourselves psychologically to become self-evolving organisms - organisms that are able to escape their biological and cultural past by adapting in whatever directions are necessary to achieve future evolutionary success.
A groundbreaking, comprehensive program for designing effective and socially equitable groups of all sizes—from businesses and social justice groups to global organizations. Whether you work in business or schools, volunteer in neighborhoods or church organizations, or are involved in social justice and activism, you understand the enormous power of groups to enact powerful and lasting change in the world. But how exactly do you design, build, and sustain effective groups? Based on the work of Nobel Prize winning economist Elinor Ostrom and grounded in contextual behavioral science, evolutionary science, and acceptance and commitment therapy (ACT), Prosocial presents a practical, step-by-step approach to help you energize and strengthen your business or organization. Using the Prosocial model, you’ll learn to design groups that are more harmonious, have better member or employee retention, have better relationships with other groups or business partners, and have more success and longevity. Most importantly, you’ll learn to target the characteristics that foster cooperation and collaboration—key ingredients for any effective group.
