"Evolutionary biologist Scott Solomon draws on the explosion of discoveries in recent years to examine the future evolution of our species. Combining knowledge of our past with current trends, Solomon offers convincing evidence that evolutionary forces still affect us today. But how will modernization--including longer lifespans, changing diets, global travel, and widespread use of medicine and contraceptives--affect our evolutionary future?" --publisher description.
Everyone wonders what tomorrow holds, but what will the real future look like? Not decades or even hundreds of years from now, but thousands or millions of years into the future. Will our species change radically? Or will we become builders of the next dominant intelligence on Earth- the machine? These and other seemingly fantastic scenarios are the very possible realities explored in Peter Ward's Future Evolution, a penetrating look at what might come next in the history of the planet. Looking to the past for clues about the future, Ward describes how the main catalyst for evolutionary change has historically been mass extinction. While many scientist direly predict that humanity will eventually create such a situation, Ward argues that one is already well underway--the extinction of large mammals--and that a new Age of Humanity is coming that will radically revise the diversity of life on Earth. Finally, Ward examines the question of human extinction and reaches the startling conclusion that the likeliest scenario is not our imminent demise but long term survival--perhaps reaching as far as the death of the Sun! Full of Alexis Rockman's breathtaking color images of what animals, plants and other organisms might look like thousands and millions of years from now, Future Evolution takes readers on an incredible journey through time from the deep past into the far future.
Delving into the history of the planet and based on reports and interviews with scientists, a science writer--traveling to rain forests, canyons, craters, and caves all over the world to explore the potential winners and losers of the next era of evolution--describes what life on earth could look like after the next mass extinction.
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.
A theory of human evolution and history based on ever-increasing mutual dependency between humans and things In this engaging exploration, archaeologist Ian Hodder departs from the two prevailing modes of thought about human evolution: the older idea of constant advancement toward a civilized ideal and the newer one of a directionless process of natural selection. Instead, he proposes a theory of human evolution and history based on “entanglement,” the ever-increasing mutual dependency between humans and things. Not only do humans become dependent on things, Hodder asserts, but things become dependent on humans, requiring an endless succession of new innovations. It is this mutual dependency that creates the dominant trend in both cultural and genetic evolution. He selects a small number of cases, ranging in significance from the invention of the wheel down to Christmas tree lights, to show how entanglement has created webs of human-thing dependency that encircle the world and limit our responses to global crises.
A New Reality: Human Evolution for a Sustainable Future provides a startling, fresh new message of understanding, perspective and hope for today’s tense, rapid-fire, kaleidoscopically changing world. A New Reality: Human Evolution for a Sustainable Future provides a startling, fresh new message of understanding, perspective and hope for today’s tense, rapid-fire, kaleidoscopically changing world. Drawn from the writings of visionary scientist Jonas Salk, who developed the polio vaccine, extended and developed by his son Jonathan, the message of the book explodes from the past and sheds light on tensions that besiege us and the currents of discord that are raging as these words are written. More importantly, it indicates a way forward out of our current situation. Written by a world-famous doctor and folk hero, based on population data, rich in visual imagery, elegantly designed, and clearly written, A New Reality is unique in the marketplace. Readable in one or two sittings, it is accessible to the general reader while at the same time being of essential value to policy makers and academics. Its brevity and simplicity of design belie the importance and sophistication of its message. “We are at a point in the course of human social evolution when the demands of survival converge with the higher ideals of humankind and the well-being and flourishing of human society. It is up to us to see that we navigate this transition, adapting to and emerging in a new reality.” —A New Reality Our country is divided and polarized. Terrorism is a major threat throughout much of the world. Mass migrations are causing national and international tension. Population growth continues to increase, especially in the developing regions of the world. Controversy rages as to the use of fossil fuels versus the development of alternative forms of energy. Disagreement continues about climate change. Opposing currents of opinion collide as to how much we should help other areas in the world and how much to help ourselves. Basic values are in conflict. More than 40 years ago, Jonas Salk understood that we are at a unique moment in the history of the human species. After centuries of increase, population growth has begun to slow and is trending toward equilibrium. This change is accompanied by an equally significant change in human values—a shift from those based on unlimited availability of resources, unremitting growth, excess, independence, competition and short-term thinking to those based on limits, equilibrium, balance, interdependence, cooperation and long-term thinking. This momentous transition is the source of far-reaching tension and conflict. The way through this difficult era is to understand its basis and to focus on new values that will be of the greatest benefit to humankind. There is an urgency, however, and failure to adapt will result in disaster both for humanity and for the planet as a whole. A New Reality delivers a message of both caution and hope. Readers across the social and political spectrum will find it a reasoned and balanced counterpoint to current social and political trends. Its elegant design and long-range perspective will appeal to general readers, policy makers, millennials, baby boomers, teachers, and students, filling a need in the marketplace for a work of positivity and wisdom in otherwise bleak times.
The hominin fossil record documents a history of critical evolutionary events that have ultimately shaped and defined what it means to be human, including the origins of bipedalism; the emergence of our genus Homo; the first use of stone tools; increases in brain size; and the emergence of Homo sapiens, tools, and culture. The Earth's geological record suggests that some evolutionary events were coincident with substantial changes in African and Eurasian climate, raising the possibility that critical junctures in human evolution and behavioral development may have been affected by the environmental characteristics of the areas where hominins evolved. Understanding Climate's Change on Human Evolution explores the opportunities of using scientific research to improve our understanding of how climate may have helped shape our species. Improved climate records for specific regions will be required before it is possible to evaluate how critical resources for hominins, especially water and vegetation, would have been distributed on the landscape during key intervals of hominin history. Existing records contain substantial temporal gaps. The book's initiatives are presented in two major research themes: first, determining the impacts of climate change and climate variability on human evolution and dispersal; and second, integrating climate modeling, environmental records, and biotic responses. Understanding Climate's Change on Human Evolution suggests a new scientific program for international climate and human evolution studies that involve an exploration initiative to locate new fossil sites and to broaden the geographic and temporal sampling of the fossil and archeological record; a comprehensive and integrative scientific drilling program in lakes, lake bed outcrops, and ocean basins surrounding the regions where hominins evolved and a major investment in climate modeling experiments for key time intervals and regions that are critical to understanding human evolution.
A major new book overturning our assumptions about how evolution works Earth’s natural history is full of fascinating instances of convergence: phenomena like eyes and wings and tree-climbing lizards that have evolved independently, multiple times. But evolutionary biologists also point out many examples of contingency, cases where the tiniest change—a random mutation or an ancient butterfly sneeze—caused evolution to take a completely different course. What role does each force really play in the constantly changing natural world? Are the plants and animals that exist today, and we humans ourselves, inevitabilities or evolutionary flukes? And what does that say about life on other planets? Jonathan Losos reveals what the latest breakthroughs in evolutionary biology can tell us about one of the greatest ongoing debates in science. He takes us around the globe to meet the researchers who are solving the deepest mysteries of life on Earth through their work in experimental evolutionary science. Losos himself is one of the leaders in this exciting new field, and he illustrates how experiments with guppies, fruit flies, bacteria, foxes, and field mice, along with his own work with anole lizards on Caribbean islands, are rewinding the tape of life to reveal just how rapid and predictable evolution can be. Improbable Destinies will change the way we think and talk about evolution. Losos's insights into natural selection and evolutionary change have far-reaching applications for protecting ecosystems, securing our food supply, and fighting off harmful viruses and bacteria. This compelling narrative offers a new understanding of ourselves and our role in the natural world and the cosmos.
