Beschreibung A Brand New Bird: How Two Amateur Scientists Created The First Genetically Engineered Animal. Long before Dolly the Sheep or bioengineered corn, there was the Red Canary-the first organism to be manipulated by genetic technology, back in the 1920s. The effort to produce a red canary invoked all of the deep issues that troubled genetic engineering decades later: the nature of genes and how they work, the specter of eugenics, and the relative roles of nature and nurture in determining what an organism is. Behavioral ecologist Tim Birkhead describes how a sweet-voiced green bird discovered by Spanish explorers in the 1300s became a craze in Renaissance Europe, how breeders gradually turned its green plumage to yellow, and how a pair of German scientists used the first bit of gene technology in the 1920s to produce an almost-red canary. But the true red canary would not come until the 1960s, when British scientists successfully bred one, and genes alone would not be sufficient to create one. A Brand New Bird is a compelling tale of a fascinating episode in the history of genetics.
A Brand New Bird: How Two Amateur Scientists Created The ~ "A Brand-new Bird" is the entertaining story of how two German bird lovers spent most of their spare and life time experimenting to create a red canary. Hans Duncker (1881-1961) and Karl Reich (1885-1970) had in common a keen interest in bird breeding. Duncker, however, had been the more academic of both and is considered as one of the first avian geneticists. Reich on the other hand had highly praised skills in rearing and cross-breeding captive birds. He had been one of the very few .

Red factor canary - Wikipedia ~ First bred in the 1920s, it is the only colour canary that has an element of red as part of its plumage. It was developed as a cross between another type of finch, the now-endangered Venezuelan red siskin (Spinus cucullata), and a yellow domestic canary (Serinus canaria forma domestica). A well-built bird, the red factor canary is about 5 1 â 2 inches (14 cm) in length. These canaries are .

Evolution: Sex, Diet and Red Ketocarotenoids - ScienceDirect ~ First, a bit of bird color background. Carotenoids â organic pigments, such as beta-carotene and zeaxanthin â are produced mostly by plants and acquired by many birds by eating seeds. Carotenoids serve as the main source of yellow, orange and red colors in feathers. Dietary carotenoid pigments tend to be yellow, but are converted in some species to red ketocarotenoids, and account for the .

Domestic canary - Wikipedia ~ First the birds were only owned by the rich, but eventually the local citizens started to breed them and, again, they became very popular. Many breeds arose through selective breeding, and they are still very popular today for their voices.
