Skin: A Natural History

This book has the rare combination of two positive traits: being genuinely scholarly and being easily approachable. We read this book for my Anthropology 101 class for these reasons (and also because it was written by a BMC alum). Jablonski's research is sound and her credentials are superb; however, the book is never above its reader's head. While topics such as the function of melanocytes and the effects of UV radiation on folates and calcium absorption may sound impossibly abstract, they are explained expertly and easily in this work. In addition to the biology of skin, this "natural history" also examines skin's function, skin diseases, decorations of the skin, and the future of medicine for skin. Throughout, the book is fascinating and well-written. It was one assigned reading that I couldn't put down!

Drawing from many fields, this work is an excellent overview of its subject. I would recommend it both for the casual reader and as a good supplemental text for an upper division class in anthropology or biology. Nina Jablonski does a great job of presenting complex material in a very readable format.

This is a great book which tells the lay person everything they may want to know about skin, without the technical jargon of the medical text book. It covers everything from the structure and uses of skin, to how and why skin and skin colors evolved, and on into ways people have ornamented their skin. Very informative, and an enjoyable read.

"It isn't good to take for granted something as important as skin," writes Nina G. Jablonski in _Skin: A Natural History_ (University of California Press). Whatever risk you have of taking skin for granted, Jablonski isn't likely to do so. She is a professor of anthropology, and her research has been done on different aspects of skin, especially skin color. She describes her new book as "not a systematic treatise or a manual, but more an idiosyncratic guidebook, replete with personal detours into topics about skin that have most engaged me in my work over the years." Engaged is a good word; she clearly loves her subject, and succeeds in communicating her enthusiasm. Skin itself is of undoubted importance. It is the largest of our organs (just because it is your outer covering and not an inner mound of tissue like your liver doesn't keep it from being a unified organ). It is, unlike the skin of most animals, basically naked, with not very much hair and no scales or feathers. Like any of our other organs, it is a product of evolution that has its current properties because it has done a good job: "Our fabric doesn't wear out, our seams don't burst, we don't spontaneously sprout leaks, and we don't expand like water balloons when we sit in the bathtub." Jablonski is right that we take skin too much for granted, and her book is a happy corrective. In a phrase that has been made famous by pop anthropology, we are "naked apes," but the reason for our hairlessness (at least compared to our primate cousins) has been disputed. Jablonski discusses the best explanation for our not having hair is that we sweat, sweating, of course, being an important function of our skin. As we developed sweating as our cooling system, we lost fur, because sweating into fur is inefficient; the cooling of a body covered with wet fur would occur at the outermost layer of fur but not at the skin so that the body itself could get cool. Jablonski has splendid chapters on skin color, the superficial characteristic on which so much history and sadness has been based. Melanin has become the governor that mediates between the opposing goals of protection from ultraviolet radiation versus synthesis of vitamin D. Humans have by now turned the "natural" and geographic order of skin color into a relative chaos because of the speedy travel that we have been able to accomplish only in the last few centuries, but the play of skin colors originally evolved on strictly geographic lines because skin molecules were being juggled as key mediators of our ability to be out in the sun. Skin colors represent evolution at work in dermatological molecules, and do not have deeper significance. With our tendency to judge and group based on superficialities, skin colors carry a lot more meaning, but not in any biological sense. Jablonski winds up her tour with thoughts about the future of skin. Oh, sure, we will always have skin, but perhaps robots will, too; our skin helps us in measu

Enhanced with the inclusion of 14 color photographs, 2 color maps, 36 black/white photographs, and 13 line drawn illustrations, "Skin: A Natural History" by Nina G. Jablonski (Head of the Department of Anthropology at The California Academy of Sciences) is a thoroughly "reader friendly" and scholarly introduction to the biological and cultural functions of human skin. "Skin" addresses such questions and issues as how and when human skin came to look, fell, and function as we know it today; why we turn pale when anxious but red when we are embarrassed or angry; why touch is one of the fundamentally important senses of the body and relates to every aspect of human life; what is the real purpose of fingerprints; skin as a canvas for self-expression; the effects of aging, environmental stress, insect bites, burns, and diseases upon skin; advancing medical technologies relevant to skin issues, and so much more. Surveying more than 300-million-years of evolutionary development as it relates to the skin of homo sapiens, "Skin" addresses the critical role skin plays in human health (including processing sunlight for Vitamin D), the role of melanin in protecting us from the sun's rays, and the advances toward to the creation of artificial skin, gene therapies, reversing the aging process of skin, and other fascinating issues related to our skin. "Skin: A Natural History" is an informed and informative addition to medical school, academic library, and Anthropological Studies collections, as well as a very highly recommended study for non-specialist general readers with an interest in the biology and sociology of skin issues.
