Book Synopsis The Convergent Evolution of Agriculture in Humans and Insects by : Ted R Schultz

Download or read book The Convergent Evolution of Agriculture in Humans and Insects written by Ted R Schultz. This book was released on 2022-02-15. Available in PDF, EPUB and Kindle. Book excerpt: Contributors explore common elements in the evolutionary histories of both human and insect agriculture resulting from convergent evolution. During the past 12,000 years, agriculture originated in humans as many as twenty-three times, and during the past 65 million years, agriculture also originated in nonhuman animals at least twenty times and in insects at least fifteen times. It is much more likely that these independent origins represent similar solutions to the challenge of growing food than that they are due purely to chance. This volume seeks to identify common elements in the evolutionary histories of both human and insect agriculture that are the results of convergent evolution. The goal is to create a new, synthetic field that characterizes, quantifies, and empirically documents the evolutionary and ecological mechanisms that drive both human and nonhuman agriculture. The contributors report on the results of quantitative analyses comparing human and nonhuman agriculture; discuss evolutionary conflicts of interest between and among farmers and cultivars and how they interfere with efficiencies of agricultural symbiosis; describe in detail agriculture in termites, ambrosia beetles, and ants; and consider patterns of evolutionary convergence in different aspects of agriculture, comparing fungal parasites of ant agriculture with fungal parasites of human agriculture, analyzing the effects of agriculture on human anatomy, and tracing the similarities and differences between the evolution of agriculture in humans and in a single, relatively well-studied insect group, fungus-farming ants.

Book Synopsis Convergent Evolution on Earth by : George R. McGhee, Jr.

Download or read book Convergent Evolution on Earth written by George R. McGhee, Jr.. This book was released on 2019-10-15. Available in PDF, EPUB and Kindle. Book excerpt: An analysis of patterns of convergent evolution on Earth that suggests where we might look for similar convergent forms on other planets. Why does a sea lily look like a palm tree? And why is a sea lily called a “lily” when it is a marine animal and not a plant? Many marine animals bear a noticeable similarity in form to land-dwelling plants. And yet these marine animal forms evolved in the oceans first; land plants independently and convergently evolved similar forms much later in geologic time. In this book, George McGhee analyzes patterns of convergent evolution on Earth and argues that these patterns offer lessons for the search for life elsewhere in the universe. Our Earth is a water world; 71 percent of the earth's surface is covered by water. The fossil record shows that multicellular life on dry land is a new phenomenon; for the vast majority of the earth's history—3,500 million years of its 4,560 million years of existence—complex life existed only in the oceans. Explaining that convergent biological evolution occurs because of limited evolutionary pathways, McGhee examines examples of convergent evolution in forms of feeding, immobility and mobility, defense, and organ systems. McGhee suggests that the patterns of convergent evolution that we see in our own water world indicate the potential for similar convergent forms in other water worlds. We should search for extraterrestrial life on water worlds, and for technological life on water worlds with continental landmasses.

Download or read book Improbable Destinies written by Jonathan B. Losos. This book was released on 2017-08-08. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Culture History and Convergent Evolution written by Huw S. Groucutt. This book was released on 2020-07-23. Available in PDF, EPUB and Kindle. Book excerpt: This volume brings together diverse contributions from leading archaeologists and paleoanthropologists, covering various spatial and temporal periods to distinguish convergent evolution from cultural transmission in order to see if we can discover ancient human populations. With a focus on lithic technology, the book analyzes ancient materials and cultures to systematically explore the theoretical and physical aspects of culture, convergence, and populations in human evolution and prehistory. The book will be of interest to academics, students and researchers in archaeology, paleoanthropology, genetics, and paleontology. The book begins by addressing early prehistory, discussing the convergent evolution of behaviors and the diverse ecological conditions driving the success of different evolutionary paths. Chapters discuss these topics and technology in the context of the Lower Paleolithic/Earlier Stone age and Middle Paleolithic/Middle Stone Age. The book then moves towards a focus on the prehistory of our species over the last 40,000 years. Topics covered include the human evolutionary and dispersal consequences of the Middle-Upper Paleolithic Transition in Western Eurasia. Readers will also learn about the cultural convergences, and divergences, that occurred during the Terminal Pleistocene and Holocene, such as the budding of human societies in the Americas. The book concludes by integrating these various perspectives and theories, and explores different methods of analysis to link technological developments and cultural convergence.
