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.'

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

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.

Popular account of what is known as the 'aquatic ape' thesis.

Your child asks, “Where did we come from?” and you wish you had a scientific explanation of human evolution to answer the question. Or you're grown up and you're still curious.How did our species become so different from the other great apes, or for that matter, from other mammals? More than a century and a half after Darwin's On the Origin of Species was published, the mystery of the “missing link” is still unresolved. Scientists agree on approximately when the split occurred between humans and our last common ancestors, but not how.Were the First People Swimmers? introduces the reader to an elegant, rigorous theory by Welsh writer Elaine Morgan, based on a hypothesis by marine biologist Alister Hardy, that our early Homo sapien ancestors evolved through natural selection in water. The theory became known as the Aquatic Ape Theory or “AAT.” Morgan wrote six books on human evolution and the theory.Were the First People Swimmers? guides you, with elementary text and playful illustrations, through empirical evidence that explains how the first humans could have started talking, lost their ability to run on all four legs, lost their fur, and acquired subcutaneous fat.Elaine Morgan provided ideas and feedback in the conception and planning of Were the First People Swimmers? The book encourages observation of nature, critical thinking and inter-generational learning.
