Traces the changing theories about continental drift due to the advances in seismology and experimental studies of the behavior of rocks under high pressure. Continental stability was the prevailing scientific view until the late 1960s, when geologists throughout the world became convinced that crustal plates, both continental and oceanic, have moved over many degrees of latitude and longitude since the Cretaceous period.
A source of profound influence and controversy, this landmark 1915 work explains various phenomena of historical geology, geomorphy, paleontology, paleoclimatology, and similar areas in terms of continental drift. 64 illustrations. 1966 edition.
It is now well known that the concept of drifting continents became an estab lished theory during the 1960s. Not long after this "revolution in the earth sciences," researchers began applying the continental drift model to problems in historical biogeography. One such problem was the origin and dispersal of the New World monkeys, the Platyrrhini. Our interests in this subject began in the late 1960s on different conti nents quite independent of one another in the cities of Florence, Italy, and Berkeley, California. In Florence in 1968, A. B. Chiarelli, through stimulating discussions with R. von Koenigswald and B. de Boer, became intrigued with the possibility that a repositioning of the continents of Africa and South America in the early Cenozoic might alter previous traditional conceptions of a North American origin of the Platyrrhini. During the early 1970s this con cept was expanded and pursued by him through discussions with students while serving as visiting professor at the University of Toronto. By this time, publication of the Journal of Human Evolution was well underway, and Dr. Chiarelli as editor encouraged a dialogue emphasizing continental drift models of primate origins which culminated in a series of articles published in that journal during 1974-75. In early 1970, while attending the University of California at Berkeley, R. L. Ciochon was introduced to the concept of continental drift and plate tectonics and their concomitant applications to vertebrate evolution through talks with paleontologist W. A. Clemens and anthropologist S. L. Washburn.
Why did American geologists reject the notion of continental drift, first posed in 1915? And why did British scientists view the theory as a pleasing confirmation? This text, based on archival resources, provides answers to these questions.
The book should be of interest not only to earth scientists, students of polar travel and exploration, and historians but to all readers who are fascinated by the great minds of science.--Henry R. Frankel, University of Missouri-Kansas City, author of The Continental Drift Controversy "Science & Education"
The resolution of the sixty-year debate over continental drift, culminating in the triumph of plate tectonics, changed the very fabric of Earth science. This four-volume treatise on the continental drift controversy is the first complete history of the origin, debate and gradual acceptance of this revolutionary theory. Based on extensive interviews, archival papers and original works, Frankel weaves together the lives and work of the scientists involved, producing an accessible narrative for scientists and non-scientists alike. This fourth volume explains the discoveries in the mid 1960s which led to the rapid acceptance of seafloor spreading theory and how the birth of plate tectonics followed soon after with the geometrification of geology. Although plate tectonics did not explain the cause or dynamic mechanism of drifting continents, it provided a convincing kinematic explanation that continues to inspire geodynamic research to the present day.
Learn how the continents have changed throughout time and how continental drift has influenced the world we live in today! Explore how the continents have drifted, from the Devonian Era to the Jurassic Period, to form the world as we know it! This beautiful book will take readers through different periods and explore the ecosystems and conditions of each time and how the changes led to where we are now. Learn about sea life, insects, animals, plants, rocks, and more! This book will be sure to capture the attention of young readers and educate them in the process!
