Wandering Gypsy has just added two very interesting books for purchase written by Carl L. Johannessen Professor Emeritus, Biogeography, at the University of Oregon.
The first book “World Trade and Biological Exchanges Before 1492” (Revised and Expanded Edition) presents a comprehensive, well-referenced, intriguing overview of historical and archaeological evidence for pre-Columbian exchange of plants, micro-fauna and animals between the Old World and New World Prior to Columbus. The current 2013 edition of the book reflects continued research and discoveries of more than fifty years of research by Professor Carl L. Johannessen Emeritus and his Co-Author John L, Sorenson, Professor Emeritus, Anthropology, in the field of early transoceanic diffusion. The tables of contents have also been reformatted for easier use. Information not available at the time of the original publication has been added to the relevant species. This book, written in a more encyclopedic style, resembles an expanded annotated bibliography and can be a great source for Graduate Student Thesis subjects. `
The second book by Professor Emeritus Carl L. Johannessen is “Pre-Columbian Sailors Changed World History” (2016). This book is written in a more easy-to- read format with an abundance of evidence proving that people from tropical cultures around the world sailed across both Pacific and Atlantic Oceans much earlier than the “European Age of Expansion”. Evidence shows that these earlier mariners sailed from to the Americas from China, India, the Pacific Islands, Africa and the Middle East, bringing plants, animals, some diseases as well as shared cultural traits with other societies that they met. This book is a must-read in order to become aware of the important contributions and true spread of civilization and cultural sharings from the tropical and subtropical worlds between non-White and non European civilizations. These books will be great additions to your library and help to expand your knowledge of Cultural Diffusion.
