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

A common tendency in the field of population ecology has been to overlook individual differences by treating populations as homogeneous units; conversely, in behavioral ecology the tendency has been to concentrate on how individual behavior is shaped by evolutionary forces, but not on how this behavior affects population dynamics. Adam Lomnicki and others aim to remedy this one-sidedness by showing that the overall dynamical behavior of populations must ultimately be understood in terms of the behavior of individuals. Professor Lomnicki's wide-ranging presentation of this approach includes simple mathematical models aimed at describing both the origin and consequences of individual variation among plants and animals. The author contends that further progress in population ecology will require taking into account individual differences other than sex, age, and taxonomic affiliation--unequal access to resources, for instance. Population ecologists who adopt this viewpoint may discover new answers to classical questions of population ecology. Partly because it uses a variety of examples from many taxonomic groups, this work will appeal not only to population ecologists but to ecologists in general.

History Within explores how the life sciences have contributed to public and popular history and to moral and political visions for a just society of the future. It shows how the sciences that deal with the evolutionary history of human groups and of humankind are powerful producers of origin narratives and experiences of kinship and belonging. Marianne Sommer looks at the collecting efforts of three key scientistsHenry Fairfield Osborn, Julian Huxley, and Luca-Luigi Cavalli-Sforzathat render the interactive creation of bio-historical knowledge possible in the first place and asks how their scientific data was translated into more broadly meaningful narratives, images, and exhibits. The bones, organisms, and molecules they studied acquire political value, she argues, in negotiations over issues of interpretation and how scientific results ought to be communicated to the public. History Within is an essential history of biology in the twentieth and twenty-first centuries."

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.

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.

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.

This early work by Alfred Russel Wallace was originally published in 1855 and we are now republishing it with a brand new introductory biography. 'On the Law Which Has Regulated the Introduction of New Species' is an article that details Wallace's ideas on the natural arrangement of species and their successive creation. Alfred Russel Wallace was born on 8th January 1823 in the village of Llanbadoc, in Monmouthshire, Wales. Wallace was inspired by the travelling naturalists of the day and decided to begin his exploration career collecting specimens in the Amazon rainforest. He explored the Rio Negra for four years, making notes on the peoples and languages he encountered as well as the geography, flora, and fauna. While travelling, Wallace refined his thoughts about evolution and in 1858 he outlined his theory of natural selection in an article he sent to Charles Darwin. Wallace made a huge contribution to the natural sciences and he will continue to be remembered as one of the key figures in the development of evolutionary theory.

The past few years have seen a revolution in our ability to map whole genome DNA from ancient humans. With the ancient DNA revolution, combined with rapid genome mapping of present human populations, has come remarkable insights into our past. This important new data has clarified and added to our knowledge from archaeology and anthropology, helped resolve long-existing controversies, challenged long-held views, and thrown up some remarkable surprises. The emerging picture is one of many waves of ancient human migrations, so that all populations existing today are mixes of ancient ones, as well as in many cases carrying a genetic component from Neanderthals, and, in some populations, Denisovans. David Reich, whose team has been at the forefront of these discoveries, explains what the genetics is telling us about ourselves and our complex and often surprising ancestry. Gone are old ideas of any kind of racial 'purity', or even deep and ancient divides between peoples. Instead, we are finding a rich variety of mixtures. Reich describes the cutting-edge findings from the past few years, and also considers the sensitivities involved in tracing ancestry, with science sometimes jostling with politics and tradition. He brings an important wider message: that we should celebrate our rich diversity, and recognize that every one of us is the result of a long history of migration and intermixing of ancient peoples, which we carry as ghosts in our DNA. What will we discover next?
