Showing results for "A History of Humanity" in Biological Sciences

How is it possible for the disciplines of cosmology, geology, anthropology, biology, and history to fit together? These 48 lectures answer that question by weaving a single story from accounts of the past developed by a variety of scholarly disciplines. The result is a story stretching from the origins of the universe to the present day and beyond, in which human history is seen as part of the history of our Earth and biosphere, and the Earth's history, in turn, is seen as part of the history of the universe.

Com base na arqueogenética, cientistas como Johannes Krause traçaram a rota das ondas migratórias que povoaram o mundo, lançando luz sobre aspectos do passado que até então permaneciam um mistério. Krause e o jornalista Thomas Trappe reescrevem um dos capítulos mais interessantes desse percurso: o povoamento da Europa. Além disso, detalham a cultura dos povos que viviam lá no período pré-histórico, formados por hábeis artesãos, por pessoas que enterravam os mortos com joias de ouro muito antes dos faraós do Egito e por caçadores de grandes animais que pereceram na Era do Gelo.

Offering a bold new understanding of who we are, where we came from, and where we are going, noted ecologist Mark Bertness argues that human beings and their civilization are the products of the same self-organization, evolutionary adaptation, and natural selection processes that have created all other life on Earth. Bertness follows the evolutionary process from the primordial soup of two billion years ago through today, exploring the ways opposing forces of competition and cooperation have led to current assemblages of people, animals, and plants.

The Big Ratchet is the story of the ratchets: the technologies and innovations, big and small, that propelled our species from hunters and gatherers on the savannahs of Africa to shoppers in the aisles of the supermarket. Our species long lived on the edge of starvation. Now we produce enough food for all 7 billion of us to eat nearly 3,000 calories every day. This is such an astonishing thing in the history of life as to verge on the miraculous. The Big Ratchet is the story of how it happened.

Humanity has reached a critical moment. Our world is unsettled and rapidly changing, and we face existential risks over the next century. Various outcomes - good and bad - are possible. Yet our approach to the future is characterized by short-term thinking, polarizing debates, alarmist rhetoric, and pessimism. In this short, exhilarating book, renowned scientist and best-selling author Martin Rees argues that humanity’s prospects depend on our taking a very different approach to planning for tomorrow.

Since 2010 it has been possible to determine a person's genetic makeup in a matter of days at an accessible cost for many millions of people. Along with this technological breakthrough there has emerged a movement to use this information to help prospective parents "eliminate preventable genetic disease." As the prospect of systematically excluding the appearance of unwanted mutations in our children comes within reach, David B. Goldstein examines the possible consequences from these types of choices.

A former endangered species biologist looks at the ongoing sixth mass extinction through the prism of human behavior, personal experience, ecology, evolutionary biology, and contemporary conservation efforts. He provides new insights into factors triggering the current mass extinction event and examines conventional wisdom regarding human intelligence. The author suggests—as humanity edges ever closer to disappearing forever—a clear-eyed, real-world rationale for resignation but also acceptance.
