The Red Canary

Sobre el libro The Red Canary de Tim Birkheard publicado por Weidenfeld & Nicolson al 2003:

The story of the first genetically engineered animal.
At the turn of the 20th century canary mania spread from the US and South Africa to Europe, with 150,000 males being raised each year to satisfy demand. Hans Duncker, a German bird enthusiast, was fascinated by the fact that in the 1870s English canary breeders had caused a scandal by feeding their Norwich canaries with red peppers to turn them orange. Duncker spent the rest of his life (1881-1961) using breeding rather than feeding to try and produce a red canary. Duncker´s ultimately unsuccessful work was picked up by an Englishman, Anthony Gill, and an American, Charles Bennett, in the 1930s. This was all long before genetically modified organisms and Dolly the sheep, but this story (with its backdrop of the rise of Nazism and eugenic policies) has huge contemporary relevance. It is a revealing tale of how an amateur obsession heralded the inherent dangers of genetic manipulation.
