Why are humans so fond of water? Why is our skin colour so variable? Why aren’t we hairy like our close ape relatives? A savannah scenario of human evolution has been widely accepted primarily due to fossil evidence; and fossils do not offer insight into these questions. Other alternative evolutionary scenarios might, but these models have been rejected. This book explores a controversial idea – that human evolution was intimately associated with watery habitats as much or more than typical savannahs. Written from a medical point of view, the author presents evidence supporting a credible alternative explanation for how humans diverged from our primate ancestors. Anatomical and physiological evidence offer insight into hairlessness, different coloured skin, subcutaneous fat, large brains, a marine-type kidney, a unique heat regulation system and speech. This evidence suggests that humans may well have evolved, not just as savannah mammals, as is generally believed, but with more affinity for aquatic habitats – rivers, streams, lakes and coasts. Key Features: Presents the evidence for a close association between riparian habitats and the origin of humans Reviews the "savannah ape" hypothesis for human origins Describes various anatomical adaptations that are associated with hypotheses of human evolution Explores characteristics from the head and neck such as skull and sinus structures, the larynx and ear structures and functions

Why do humans differ from other primates? What do those differences tell us about human evolution? Elaine Morgan gives a revolutionary hypothesis that explains our anatomic anomalies: why we walk on two legs, why we are covered in fat, why we can control our rate of breathing? The answers point to one conclusion: millions of years ago our ancestors were trapped in a semi-aquatic environment. In presenting her case Elaine Morgan forces scientists to question accepted theories of human evolution.

This thought-provoking text presents the Aquatic Ape Theory, with new information, new questions and a wealth of documentary evidence. It is the most persuasive, closely argued case yet offered to explain the mystery of human origins.'

The book starts from the observation that humans are very different from the other primates. Why are we naked? Why do we speak? Why do we walk upright? Fifty years ago, in 1960, marine biologist Sir Alister Hardy tried to answer this when he announced his so-called aquatic hypothesis: human ancestors did not live in dry savannahs as traditional anthropology assumes, but have adapted to live at the edge between land and water, gathering both terrestrial and aquatic foods. This eBook is an up-to-date collection of the views of the most important protagonists of this long-neglected theory of huma.

ìAt long last, a readable, accessible, user friendly introduction to evolutionary psychology written by a rising star in the field. This book, filled with a broad array of fascinating topics, is bound to further whet the appetite of a growing number of students who have been inspired by this provocative, yet eminently testable approach to human behavior.î Gordon G. Gallup Jr., PhD University at Albany "A frolicking, down-to-earth, and informative introduction to the ever evolving and controversial field of evolutionary psychology." Scott Barry Kaufman, PhD Author, Ungifted: Intelligence Redefined ìGlenn Geher has created a text that is both comprehensive in coverage and scope and very accessible. It should be a welcome addition to the field that serves to further individuals' understanding of Evolutionary Psychology.î T. Joel Wade, PhD Professor and Chair of Psychology, Bucknell University This is a concise and student-friendly survey of the burgeoning field of evolutionary psychology (EP) and the controversies that surround it. Evolutionary psychology is an approach to studying human behavior that is rooted in modern evolutionary theory. Firmly grounded in the theoretical and research literature of EP, the book addresses the core theories, approaches, applications, and current findings that comprise this discipline. It is unique in its interdisciplinary focus, which encompasses EPís impact on both psychological and non-psychological disciplines. Written by an eminent evolutionary psychologist who is President of the Northeastern Evolutionary Psychology Society, the text examines psychological processes that lead to human survival and those that may lead to reproductive benefitsósometimes even at a cost to survival. It cites a rich body of literature that provides insights into the role of sexual selection in shaping the human mind. The text presents current research on such important domains of EP as childhood, courtship, intrasexual competition, sex, pair-bonding, parenting, familial relations, non-familial relations, aggression, and altruism. Considering the potential of EP to mitigate some of our greatest social problems, the text examines the ways in which EP can be applied to society and religion. It also offers a thoughtful, balanced approach to such controversies in EP as the issues of genetic determinism, racism, and sexism. Key Features: Provides a broad survey one of the most recent, widely researched, and controversial fields to emerge in psychology over the past 20 years Written by an eminent evolutionary psychologist who is President of the Northeastern Evolutionary Psychology Society Presents EP concepts in an accessible, student-friendly way Offers a unique interdisciplinary focus that addresses the impact of EP on both psychological and non-psychological disciplines Emphasizes controversies within the field of evolutionary psychology and includes critiques of EP from people outside this discipline

This technical and well-illustrated guide for archaeologists and conservators aims to `provide a methodology for the identification of the woody taxa used to manufacture artefacts recovered from archaeological excavations', to provide the anatomical descriptions of the taxa and to present a list of characters of the taxa. The guide is heavily illustrated with photographs, maps, and tables to allow easy identification.
