However, the ideas are so new to most people, it also serves as a simple introduction to Elaine Morgan’s Aquatic Ape Theory for adults. As you go through this book, please wonder how we came to be. Here is the best story of human origins I have ever encountered, and it’s probably the true one. Please test this theory against your own knowledge and observations. Judy Kaul Writer-Illustrator Elaine Morgan’s Aquatic Ape Theory of Human Evolution is firmly rooted in Charles Darwin’s Theory of Natural Selection: Those members of a species that are best adapted to their environment tend to thrive and reproduce most successfully; and those that are best adapted to a new or changing environment may evolve into a new species. Darwin’s theory, which transformed scientific thought in the 19th century, left open the question of how our own species, Homo sapiens, branched off from the other great apes and acquired our distinctive characteristics. Over the years many paleontologists and other scientists have endeavored to answer this question, but so far, in the early 21st century, there is still no 7 consensus on how the split occurred. Those who have undertaken the search have encountered a complex evolutionary trail and a scarcity of fossils. But finding the answer was made more difficult than necessary by the general belief that early humans evolved alongside other terrestrial mammals, in forests and on savannahs, not in water along ancient shores. The widespread assumption that our species evolved on land made it very difficult to explain how we became so radically different from all other landdwelling mammals. For example, we are bipedal and we lack fur. However, almost all other terrestrial mammals can run on all fours (which affords them speed to catch prey and/or to outrun predators); and almost all terrestrial mammals benefit from the many advantages of having fur (for example, fur insulates the body and protects the skin, and it gives some young mammals, especially primates, a way of holding onto their mothers). In order to understand how our early human ancestors evolved away from quadrupedalism, fur and many other adaptations that were advantageous on land, there was a need for a paradigm shift. The shift actually had its beginning in 1929 when a marine biologist on an Arctic expedition made a pivotal observation. Sir Alister Hardy noticed that “blubber” in marine mammals was very similar to “subcutaneous fat” in humans. He hypothesized that Homo sapiens had acquired subcutaneous fat the same way whales, dolphins and seals had -- through the Page 8 of 44 Were the First People Swimmers? process of natural selection while they were living in water. In 1960, when Hardy unveiled this idea, he identified some other physiological characteristics of humans, including bipedalism and lack of fur, that could also be explained by adaptation to water. Hardy’s hypothesis, that our species differentiated in water and subsequently re-adapted to living on land, made sense to Welsh writer Elaine Morgan. During a period of almost 40 years, Morgan undertook an extensive study of scientific data and research from various fields, and she compiled an enormous body of scientific evidence that supported Hardy’s hypothesis. This work became known as “The Aquatic Ape Theory.” As in Darwin’s theory, there was no “silver bullet” of proof but the circumstantial evidence was overwhelming. Morgan looked painstakingly for any evidence that would undermine or disprove the theory but she never found it. Academia has largely overlooked the Aquatic Ape Theory. Morgan’s first book on the subject, The Descent of Woman (1972) was a best-seller that combined Hardy’s hypothesis with a feminist perspective. Her subsequent books on human evolution were scientifically rigorous. All are listed on page 44 of this book. Morgan was received into the Linnaean Society in 2008, and in 2009 she was appointed an Officer of the Order of the British Empire (OBE). Were the First People Swimmers? is a simple, illustrated introduction to Elaine Morgan’s Aquatic Ape Theory. Acknowledgments I wrote to Elaine Morgan in 2007 because I wanted her advice on illustrating “aquatic apes.” I had read some of her books and my mind was bursting with images. (I’m an instructional designer with a penchant for visuals.) This was the beginning of a 5-year correspondence during which Elaine 1) got me to understand there was no scientific way of knowing what the original aquatic apes looked like, 2) suggested that I write and illustrate a children’s book on the subject, and 3) mentored me along as Were the First People Swimmers? took shape. Sadly, she died in July 2013, before the book was finished. I’m grateful to Elaine Morgan for much more than this book. Her writings transformed my understanding about who we are as a species and how we fit into the web of life on Earth. I continue learning as I make new connections between our early ancestors and the way we are today. Many other individuals also helped make this book happen. Thank you very much, and thank you to the Society of Children’s Book Writers and Illustrators. 8 We’re mammals! 9 Were the First People Swimmers? Page 10 of 44 Mammals are warm blooded animals that have fur or hair, and the mothers nurse their babies with milk from their bodies. Mammals live in warm and cold climates, on land, in water, in trees and underground. Bats are mammals that can fly. 10 Page 11 of 44 Were the First People Swimmers? Chimps are a lot like people! 11 Were the First People Swimmers? Page 12 of 44 People are a lot like chimpanzees, bonobos and other apes; and we are also very different. We don’t have fur. We run on two legs, not four, and we can talk in sentences but they can’t. 12 Page 13 of 44 Were the First People Swimmers? Scientists agree that many millions of years ago our ancestors were more like chimpanzees and bonobos than they were like people. Scientists also agree that our ancestors began to be more like people about six or seven million years ago. Scientists don’t agree on what happened that made people different from the other apes. 13 Were the First People Swimmers? Page 14 of 44 We don’t know what our ancestors looked like before there were people, but they might have looked something like this. 14 Were the First People Swimmers? Page 15 of 44 I wonder how come I can’t run like that! 15 Were the First People Swimmers? Almost all mammals that live on land, including apes, run on all fours. They’re fast and they make it look easy, but it’s almost impossible for us to run on our hands and feet. Page 16 of 44 16 Were the First People Swimmers? 17 Page 17 of 44 When we run, our bodies are straightened out and we only use our two long legs. We’re not as fast as most four-legged mammals. Were the First People Swimmers? But we can wade into deeper water . . . Page 18 of 44 18 Were the First People Swimmers? 19 . . . and we can swim faster because we don’t always have to do the “dog-paddle.” Page 19 of 44 Were the First People Swimmers? The fastest swimmers all straighten out when they swim, like a streamlined boat or submarine. Page 20 of 44 20 Page 21 of 44 Were the First People Swimmers? Maybe the first people straightened out as they waded in water and swam. 21 Were the First People Swimmers? We don’t know what the first people looked like but they might have looked something like this. Page 22 of 44 22 Were the First People Swimmers? How come I don’t have fur like that? 23 Page 23 of 44 Were the First People Swimmers? Almost all mammals that live on land have fur. Fur is very useful to them in many ways. Page 24 of 44 24 Were the First People Swimmers? 25 Page 25 of 44 Mammals that live in water don’t have fur; fur would slow them down. They have extra fat under their skin which helps them keep warm; and fat also helps them float up to the surface to breathe. Were the First People Swimmers? Page 26 of 44 Mammals that go back and forth between water and land have different amounts of fur and fat. 26 Were the First People Swimmers? 27 Page 27 of 44 These mammals can also go back and forth between water and land. Were the First People Swimmers? Page 28 of 44 People, like elephants, hippopotamuses, whales, and dolphins, don’t have much fur or hair, and we also have fat under our skin. Extra fat is useful in water but it’s a problem on land. 28 Page 29 of 44 Were the First People Swimmers? Maybe the first people had less fur or hair so they could swim better. Maybe fat under their skin helped them keep warm and helped them float. 29 Were the First People Swimmers? We don’t know what the first people looked like but they might have looked something like this. Page 30 of 44 30 Were the First People Swimmers? Hair is a lot like fur! 31 Page 31 of 44 Were the First People Swimmers? Page 32 of 44 Fur is something baby primates can hang onto. 32 Page 33 of 44 Were the First People Swimmers? Maybe the first people had hair on their heads so the babies could hold on. 33 Were the First People Swimmers? We don’t know what the first people looked like but they might have looked something like this. Page 34 of 44 34 Page 35 of 44 Were the First People Swimmers? I wish you could talk! Arf! 35 Page 36 of 44 Were the First People Swimmers? neigh! oink! roar! baa! ooo-ooo! squeek! Mammals have been making sounds with their voices for a very long time. Of course we can too. And . . . 36 Were the First People Swimmers? Page 37 of 44 People can talk in long sentences! 37 . . . we can take a deep breath, and as we let the air out we can make a lot of sounds, one after the other. Were the First People Swimmers? Page 38 of 44 Mammals that swim under water have to come up to the surface to breathe. In water they hold their breath or they breathe out. 38 Page 39 of 44 Were the First People Swimmers? Maybe the first people let the air out slowly as they swam underwater. Today we can let our breath out slowly as we talk in sentences. 39 Were the First People Swimmers? We don’t know what the first people looked like but they might have looked something like this. Page 40 of 44 40 Were the First People Swimmers? 41 Page 41 of 44 Many people love to swim and play in water today. Babies can learn to swim before they can walk or talk. Babies can float and keep warm in water because they have baby fat. Were the First People Swimmers? Page 42 of 44 How did we get to be this way? Maybe the first people were swimmers. . 42 Were the First People Swimmers? 43 Page 43 of 44 Page 44 of 44 Were the First People Swimmers?
