A unique, interdisciplinary and up-to-date treatment exploring human migration and its role in creating novel ecosystems over the long term.

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.

Wilson Literary Science Writing Award A Library Journal Best Science & Technology Book of 2020 A Publishers Weekly Best Nonfiction Book of 2020 2020 Goodreads Choice Award Semifinalist in Science & Technology A prize-winning journalist upends our centuries-long assumptions about migration through science, history, and reporting--predicting its lifesaving power in the face of climate change. The news today is full of stories of dislocated people on the move. Wild species, too, are escaping warming seas and desiccated lands, creeping, swimming, and flying in a mass exodus from their past habitats. News media presents this scrambling of the planet's migration patterns as unprecedented, provoking fears of the spread of disease and conflict and waves of anxiety across the Western world. On both sides of the Atlantic, experts issue alarmed predictions of millions of invading aliens, unstoppable as an advancing tsunami, and countries respond by electing anti-immigration leaders who slam closed borders that were historically porous. But the science and history of migration in animals, plants, and humans tell a different story. Far from being a disruptive behavior to be quelled at any cost, migration is an ancient and lifesaving response to environmental change, a biological imperative as necessary as breathing. Climate changes triggered the first human migrations out of Africa. Falling sea levels allowed our passage across the Bering Sea. Unhampered by barbed wire, migration allowed our ancestors to people the planet, catapulting us into the highest reaches of the Himalayan mountains and the most remote islands of the Pacific, creating and disseminating the biological, cultural, and social diversity that ecosystems and societies depend upon. In other words, migration is not the crisis--it is the solution. Conclusively tracking the history of misinformation from the 18th century through today's anti-immigration policies, The Next Great Migration makes the case for a future in which migration is not a source of fear, but of hope.

An integrative approach linking the causes of migration to genetic consequences for human evolution.

Now that so many ecosystems face rapid and major environmental change, the ability of species to respond to these changes by dispersing or moving between different patches of habitat can be crucial to ensuring their survival. Understanding dispersal has become key to understanding how populations may persist. Dispersal Ecology and Evolution provides a timely and wide-ranging overview of the fast expanding field of dispersal ecology, incorporating the very latest research. The causes, mechanisms, and consequences of dispersal at the individual, population, species, and community levels are considered. Perspectives and insights are offered from the fields of evolution, behavioural ecology, conservation biology, and genetics. Throughout the book theoretical approaches are combined with empirical data, and care has been taken to include examples from as wide a range of species as possible - both plant and animal.

The first publication to outline the complex global story of human migration and dispersal throughout the whole of human prehistory. Utilizing archaeological, linguistic and biological evidence, Peter Bellwood traces the journeys of the earliest hunter-gatherer and agriculturalist migrants as critical elements in the evolution of human lifeways. The first volume to chart global human migration and population dispersal throughout the whole of human prehistory, in all regions of the world An archaeological odyssey that details the initial spread of early humans out of Africa approximately two million years ago, through the Ice Ages, and down to the continental and island migrations of agricultural populations within the past 10,000 years Employs archaeological, linguistic and biological evidence to demonstrate how migration has always been a vital and complex element in explaining the evolution of the human species Outlines how significant migrations have affected population diversity in every region of the world Clarifies the importance of the development of agriculture as a migratory imperative in later prehistory Fully referenced with detailed maps throughout

The epic story of human evolution, from our primate beginnings more than five million years ago to the agricultural era Over the course of five million years, our primate ancestors evolved from a modest population of sub-Saharan apes into the globally dominant species Homo sapiens. Along the way, humans became incredibly diverse in appearance, language, and culture. How did all of this happen? In The Five-Million-Year Odyssey, Peter Bellwood synthesizes research from archaeology, biology, anthropology, and linguistics to immerse us in the saga of human evolution, from the earliest traces of our hominin forebears in Africa, through waves of human expansion across the continents, and to the rise of agriculture and explosive demographic growth around the world. Bellwood presents our modern diversity as a product of both evolution, which led to the emergence of the genus Homo approximately 2.5 million years ago, and migration, which carried humans into new environments. He introduces us to the ancient hominins—including the australopithecines, Homo erectus, the Neanderthals, and others—before turning to the appearance of Homo sapiens circa 300,000 years ago and subsequent human movement into Eurasia, Australia, and the Americas. Bellwood then explores the invention of agriculture, which enabled farmers to disperse to new territories over the last 10,000 years, facilitating the spread of language families and cultural practices. The outcome is now apparent in our vast array of contemporary ethnicities, linguistic systems, and customs. The fascinating origin story of our varied human existence, The Five-Million-Year Odyssey underscores the importance of recognizing our shared genetic heritage to appreciate what makes us so diverse.
