Wade Davis (born December 14, 1953) is a Canadian anthropologist, ethnobotanist, author, and photographer whose work has focused on worldwide indigenous cultures, especially in North and South America and particularly involving the traditional uses and beliefs associated with psychoactive plants. Davis came to prominence with his 1985 best-selling book The Serpent and the Rainbow about the zombies of Haiti. Davis is Professor of Anthropology and the BC Leadership Chair in Cultures and Ecosystems at Risk at the University of British Columbia.

Davis has published popular articles in Outside, National Geographic, Fortune, and Condé Nast Traveler.

Davis is an Explorer-in-Residence at the National Geographic Society. Named by the NGS as one of the Explorers for the Millennium, he has been described as “a rare combination of scientist, scholar, poet and passionate defender of all of life’s diversity.” In recent years his work has taken him to East Africa, Borneo, Nepal, Peru, Polynesia, Tibet, Mali, Benin, Togo, New Guinea, Australia, Colombia, Vanuatu, Mongolia, and the high Arctic of Nunuvut and Greenland.

An ethnographer, writer, photographer, and filmmaker, Davis holds degrees in anthropology and biology and received his Ph.D. in ethnobotany, all from Harvard University. Mostly through the Harvard Botanical Museum, he spent over three years in the Amazon and Andes as a plant explorer, living among fifteen indigenous groups in eight Latin American nations while making some 6000 botanical collections. In 1974, at the age of 20, he crossed the Darien Gap on foot in the company of the celebrated English author and amateur explorer, Sebastian Snow.[1] His work later took him to Haiti to investigate folk preparations implicated in the creation of zombies, an assignment that led to his writing Passage of Darkness (1988) and The Serpent and the Rainbow (1986), an international best seller and, loosely, the basis of a horror film.

His other books include Penan: Voice for the Borneo Rain Forest (1990), Shadows in the Sun (1993), Nomads of the Dawn (1995), The Clouded Leopard (1998), Rainforest (1998), Light at the Edge of the World (2001), The Lost Amazon (2004), Grand Canyon (2008), Book of Peoples of the World (ed. 2008) and One River (1996), which was nominated for the 1997 Governor General's Literary Award for Nonfiction. His books have been translated into fourteen languages, including Basque, Serbian, Japanese and Malay.

A native of British Columbia, Davis, a licensed river guide, has worked as park ranger, forestry engineer, and conducted ethnographic fieldwork among several indigenous societies of northern Canada. He has published 180 scientific and popular articles on subjects ranging from Haitian vodoun and Amazonian myth and religion to the global biodiversity crisis, the traditional use of psychotropic drugs, and the ethnobotany of South American Indians. Davis has written for National Geographic, Newsweek, Premiere, Outside, Omni, Harpers, Fortune, Men's Journal, Condé Nast Traveler, Natural History, Scientific American, National Geographic Traveler, The New York Times, Wall Street Journal, Washington Post, The Globe and Mail, and numerous other international publications. Davis is a Fellow of the International League of Conservation Photographers (iLCP)

His photographs have appeared in some 20 books and more than 80 magazines, journals and newspapers, including National Geographic, Time, GEO, People, Men’s Journal, Outside, and National Geographic Adventure. They have been exhibited at the International Center of Photography (I.C.P.), the Marsha Ralls Gallery, Washington, D.C., the United Nations (Cultures on the Edge exhibition 2004), the Carpenter Center of Harvard University, and the Utama Center, Kuala Lumpur, Malaysia. Select images are part of the permanent collection of the U.S. State Department, Africa and Latin America Bureaus.

Davis is the co-curator of The Lost Amazon: The Photographic Journey of Richard Evans Schultes, first exhibited at the National Museum of Natural History, Smithsonian Institution, and currently touring Latin America.

A first collection of Davis’ photographs, Light at the Edge of the World, appeared in 2001 published by National Geographic Books, Bloomsbury and Douglas & McIntyre. A second collection is under contract for fall 2011 publication with Douglas & McIntyre.

Davis’ research has been the subject of more than 800 media reports and interviews in Europe, North and South America and the Far East, and has inspired numerous documentary films as well as three episodes of the television series, The X-Files.

A professional speaker for over twenty years, Davis has lectured at the American Museum of Natural History, Smithsonian Institution, and at the TED Conference. His clients have included amongst others Microsoft, Shell, Hallmark, Fidelity Investments, Bank of Nova Scotia, Mackenzie Financial, Healthcare Association of Southern California, National Science Teachers Association, NDMA (Non-prescriptive Drug Manufacturers Association), International Baccalaureate, European Council of International Schools, Canadian Society of Petroleum Geologists, Canadian Association of Exploration Geophysicists, American Trial Lawyer’s Association, American Judges Association, American Bankers Association, Centaur Technology, Canadian Association of Actuaries, Canadian Veterinary Medical Association, as well as several leading pharmaceutical companies including Warner-Lambert, Bayer, Miles, Bristol-Myers, and Abbott Laboratories.

An Honorary Research Associate of the Institute of Economic Botany of the New York Botanical Garden, he is a Fellow of the Linnean Society, Fellow of the Explorer's Club, and Fellow of the Royal Geographical Society and Fellow of the Royal Canadian Geographical Society. Davis was a founding board member of the David Suzuki Foundation and he recently completed a six-year term on the board of the Banff Centre, Canada’s leading institution for the arts. He has served on the Board of Directors since 2009 for the Amazon Conservation Association, whose mission is to conserve the biological diversity of the Amazon.[2] In 2009 he delivered the CBC Massey Lectures, Canada’s most prestigious public intellectual forum.

Davis was the series creator, host and co-writer of Light at the Edge of the World, a four-hour ethnographic documentary series, shot in Discovery Channel in 1990.

Davis has recently completed a new four-hour series for the National Geographic, Ancient Voices/Modern World, which was shot in Australia, Mongolia, and Colombia. It is currently airing worldwide on the National Geographic Channel as the second season of Light at the Edge of the World.

Davis is a member of the International Advisory Board, Hunt Consolidated, PLNG, and is also currently engaged in a three-year campaign, Journey to Zero, an effort sponsored by Nissan and TBWA to support zero emission vehicles.

When not in the field, Davis and his wife Gail Percy divide their time between Washington, D.C., Vancouver and the Stikine Valley of northern British Columbia. They have two children.

In late 2013, Davis joined the University of British Columbia as research and teaching faculty.[3]

Criticisms of work in Haiti

In 1983, Davis first advanced his hypothesis that tetrodotoxin (TTX) poisoning could explain the existence of Haitian zombies.[4] This idea has been controversial and his popular 1985 follow up book (The Serpent and the Rainbow) elaborating upon this claim has been criticized for a number of scientific inaccuracies.[5] One of these is the suggestion that Haitian witchdoctors can keep “zombies” in a state of pharmacologically induced trance for many years.[6] As part of his Haitian investigations, Davis commissioned the exhumation of a recently buried child.[7][8] (Dead human tissue is supposed to be a part of the “zombie powder” used by witchdoctors to produce zombies.) This has been criticized in the professional literature as a breach of ethics.[9][10]

The strictly scientific criticism of Davis’ zombie project has focused on the claims about the chemical composition of the “zombie powder”. Several samples of the powder were analyzed for TTX levels by experts in 1986. They reported[11] that only “insignificant traces of tetrodotoxin [were found] in the samples of ‘zombie powder’ which were supplied for analysis by Davis” and that “it can be concluded that the widely circulated claim in the lay press to the effect that tetrodotoxin is the causal agent in the initial zombification process is without factual foundation”. Davis’ claims were subsequently defended by other scientists doing further analyses[12] and these findings were criticized in turn for poor methodology and technique by the original skeptics.[13] Aside from the question of whether or not “zombie powder” contains significant amounts of TTX, the underlying concept of “tetrodotoxin zombification” has also been questioned more directly on a physiological basis.[14] TTX, which blocks sodium channels on the neural membrane, produces numbness, slurred speech, and possibly paralysis or even respiratory failure and death in severe cases. As an isolated pharmacological agent, it is not known to produce the trance-like or “mental slave” state typical of zombies in Haitian mythology, or Davis’ descriptions, although one might consider the effects of "set and setting" in combination with the drug.

Others have argued that Davis did not suggest that the purported TTX-containing powder maintained the "mental slaves," only that it produced the initial death that, with the subsequent separate pharmacologic resurrection, convinced the victim and those who knew them that they had become zombies. Purported zombie cases such as Clairvius Narcisse were, according to Davis, kept biddable by regular doses of the poisonous 'zombi cucumber', Datura stramonium which produces amnesia, delirium and suggestibility.[15]

Otherwise, the effects of fugu TTX poisonings in Japan agree with the reports of zombification.

Awards and accolades

Davis is the recipient of numerous awards including the Gold Medal of the Royal Canadian Geographical Society (2009), the 2002 Lowell Thomas Medal (The Explorers Club) and the 2002 Lannan Foundation $125,000 prize for literary non-fiction. He has been granted Honorary Degrees (Doctorate of Sciences) from University of Victoria (2003), University of Guelph (2008), Colorado College (2010) and University of Northern British Columbia (Doctorate of Laws 2010). In 2004 he was made an Honorary Member of The Explorers Club, one of twenty. In 2009 he was selected to be the speaker for the Massey Lectures, for his publication, The Wayfinders.[16] In 2011 he received The Explorers Medal, the highest award of The Explorers Club. He was awarded the David Fairchild Medal for Plant Exploration, considered the most prestigious prize for botanical exploration, in 2012.[17]
