Henry Fairfield Osborn Knihy

Dedicated to Huxley and Balfour, this work explores the logic of Darwin as applied to paleontology, emphasizing the importance of clear communication for both specialists and laymen. The author reflects on the challenge of addressing diverse audiences while maintaining accuracy and engagement. Inspired by Huxley’s belief in the duty of scientists to disseminate knowledge, the author aims to captivate both seasoned paleontologists and newcomers to the field. While some sections are dense and documentary in nature, the primary focus shifts from descent to the time and place of mammals' origins, migrations, and extinctions. The work examines the historical context of these events, considering past environments, including paleogeography, climate changes, and their impact on plant life, which served as the food source for mammals. By integrating geology, geography, botany, and climate, the author provides a comprehensive understanding of mammalian evolution. This volume is a significant contribution to the study of Cenozoic mammals, inviting readers to appreciate the intricate tapestry of life’s history.
