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. .

Faces in the Forest: First Nations Art Created on Living Trees
In Faces in the Forest Michael Blackstock, a forester and an artist, takes us into the sacred forest, revealing the mysteries of carvings, paintings, and writings done on living trees by First Nations people. Blackstock details this rare art form through oral histories related by the Elders, blending spiritual and academic perspectives on Native art, cultural geography, and traditional ecological knowledge. Faces in the Forest begins with a review of First Nations cosmology and the historical references to tree art. Blackstock then takes us on a metaphorical journey along the remnants of trading and trapping trails to tree art sites in the Gitxsan, Nisga'a, Tlingit, Carrier, and Dene traditional territories, before concluding with reflections on the function and meaning of tree art, its role within First Nations cosmology, and the need for greater respect for all of our natural resources. This fascinating study of a haunting and little-known cultural phenomenon helps us to see our forests with new eyes..
