In the 17th century, Descartes put forth the metaphor of the machine to explain the functioning of living beings. In the 18th century, La Mettrie extended the metaphor to man. The clock was then used as the paradigm of the machine. In the 20th century, this metaphor still held but the clock was replaced by a computer. Nowadays, the organism is viewed as a robot obeying signals emanating from a computer program controlled by genetic information. This book shows that such a conception leads to contradictions not only in the theory of biology but also in its experimental research program, thereby impeding its development. The analysis of this problem is based on the most recent experimental data obtained in molecular biology as well as the history and philosophy of biology. It shows that the machine theory did not succeed in breaking with Aristotle's finalism. The book presents a new approach to biological systems based on cellular Darwinism. Genes are ruled by probabilistic mechanisms allowing cells to differentiate stochastically. Embryo development is not governed by a determinist genetic program but by natural selection occurring among cell populations inside the organism. This theory has considerable philosophical consequences. Man may be a machine but he is a random one.

On the Origin of Species (or, more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life),[3] published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology.[4] Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation.

Science need not be dull and bogged down by jargon, as Richard Dawkins proves in this entertaining look at evolution. The themes he takes up are the concepts of altruistic and selfish behaviour; the genetical definition of selfish interest; the evolution of aggressive behaviour; kinshiptheory; sex ratio theory; reciprocal altruism; deceit; and the natural selection of sex differences. 'Should be read, can be read by almost anyone. It describes with great skill a new face of the theory of evolution.' W.D. Hamilton, Science

This book examines the history behind the formulation, implementation, and evaluation of population policies in the more developed, the less developed, and the least developed countries from 1950 until today, as well as their future prospects. It links population policies with the theories of the demographic, epidemiological, and migratory transitions. It begins by summarizing the demographic situation around the world, with an emphasis on population policies and their underlying theories. Then, it reviews the early efforts to reduce mortality and fertility in the developing countries. This is followed by a description of the internationalization of the debate on population issues and the transformation of these programs into more formal population policies, particularly in the developing countries. The book reviews also the situation of the developed countries and their specific challenges – sub-replacement fertility, population aging, and immigration – and examines the effectiveness of population policies. It also explores the way forward and future prospects for population policies over the next decades. The book provides numerous concrete examples from all over the world, and show how population policies are actually implemented and what have been their successes as well as their constraints. Above all, the book highlights the importance of understanding underlying demographic trends when assessing the development prospects of any country. The book is recommended for not only demographers, social scientists, and policymakers but also economists and political scientists who are interested in social and demographic change around the world. Demography students and researchers who are interested in applying knowledge on population trends and prospects in designing and evaluating public policies will find this an invaluable reference work.

Since its original landmark publication in 1980, A People's History of the United States has been chronicling American history from the bottom up, throwing out the official version of history taught in schools -- with its emphasis on great men in high places -- to focus on the street, the home, and the, workplace. Known for its lively, clear prose as well as its scholarly research, A People's History is the only volume to tell America's story from the point of view of -- and in the words of -- America's women, factory workers, African-Americans, Native Americans, the working poor, and immigrant laborers. As historian Howard Zinn shows, many of our country's greatest battles -- the fights for a fair wage, an eight-hour workday, child-labor laws, health and safety standards, universal suffrage, women's rights, racial equality -- were carried out at the grassroots level, against bloody resistance. Covering Christopher Columbus's arrival through President Clinton's first term, A People's History of the United States, which was nominated for the American Book Award in 1981, features insightful analysis of the most important events in our history. Revised, updated, and featuring a new after, word by the author, this special twentieth anniversary edition continues Zinn's important contribution to a complete and balanced understanding of American history.

The Arthur M. Sackler Colloquia of the National Academy of Sciences address scientific topics of broad and current interest, cutting across the boundaries of traditional disciplines. Each year, four or five such colloquia are scheduled, typically two days in length and international in scope. Colloquia are organized by a member of the Academy, often with the assistance of an organizing committee, and feature presentations by leading scientists in the field and discussions with a hundred or more researchers with an interest in the topic. Colloquia presentations are recorded and posted on the National Academy of Sciences Sackler colloquia website and published on CD-ROM. These Colloquia are made possible by a generous gift from Mrs. Jill Sackler, in memory of her husband, Arthur M. Sackler.
