Water Transport Origns Early Evolution

Water Transport

First published in 1946, this book presents a comprehensive account regarding the origins and early evolution of water transport written by the renowned British ethnographer and zoologist James Hornell (1865-1949). The focus of the text is on different types of transport, and it is divided into three main sections: the first section is on 'Floats, Rafts and Kindred Craft', the second is on 'Skin Boats: Coracles, Curraghs, Kayaks and their Kin' and the third is on 'Bark Canoes, Dugouts and Plank-Built Craft'. Numerous illustrative figures and a detailed bibliography are also included. This book will be of value to anyone with an interest in archaeology, anthropology and the history of water transport.

Water Transport Origns & Early Evolution

The Origin and Early Evolution of Life

Origin and Early Evolution of Life draws on evidence from molecular genetics, the structure and function of extant organisms, and geology. It covers the period from about 4 billion years ago, when life is thought to have originated, to about 600 million years ago when multicellular organisms first arose. There are significant gaps in our understanding of the earliest evolution of life forms, but an insight into the topic leads to a more profound understanding of life itself. Particular emphasis is placed on the fact that although life arose very soon after the origin of the Earth, it was represented only by simple microbial life forms for approximately 85% of this time. Increase in complexity beyond the microbial level took place only very late in the history of life.
