Cloning

A Biologist Reports

Robert Gilmore McKinnell

University of Minnesota Press, 1985

Cloning was first published in 1985. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions.

Cloning has become in recent years a subject of widespread speculation: the word is a source of fear and wonder, the concept a jumping-off point for the fantasies of cartoonists, film producers, and novelists. With this book, cell biologist Robert Gilmore McKinnell provides the first clear scientific explanation of the procedure for general readers.

Cloning is best defined as the asexual reproduction of genetic duplicates. The word clone derives from the Greek word for a twig or a slip, and the first "cloners" were in fact horticulturalists. Early attempts to clone animals culminated in 1952 when biologists reported that they had produced frogs by transplanting genetic material from an embryonic body cell into an egg from which the nucleus had been removed.

In this account, McKinnell traces the historical background of cloning and describes in detail the modern procedure used in the cloning of frogs—the highest animal thus far cloned. He emphasizes that the purpose of cloning is not to produce numerous frogs—or people—but rather to serve as a tool in biological research—to achieve greater understanding of cancer and aging, immunobiology and the differentiation of cells.

McKinnell also deals with questions about potential mammalian clones and examines the social, ethical, and biological problems we face in our considerations about human cloning. He concludes that human clones are not necessary for research purposes and that the diversity achieved with sexual reproduction is far more desirable than the sameness of cloned creatures.

Dolly Mixtures

The Remaking of Genealogy

Sarah Franklin

Duke University Press, 2007

While the creation of Dolly the sheep, the world's most famous clone, triggered an enormous amount of discussion about human cloning, in Dolly Mixtures the anthropologist Sarah Franklin looks beyond that much-rehearsed controversy to some of the other reasons why the iconic animal's birth and death were significant. Building on the work of historians and anthropologists, Franklin reveals Dolly as the embodiment of agricultural, scientific, social, and commercial histories which are, in turn, bound up with national and imperial aspirations. Dolly was the offspring of a long tradition of animal domestication, as well as the more recent histories of capital accumulation through selective breeding, and enhanced national competitiveness through the control of biocapital. Franklin traces Dolly's connections to Britain's centuries-old sheep and wool markets (which were vital to the nation's industrial revolution) and to Britain's export of animals to its colonies—particularly Australia—to expand markets and produce wealth. Moving forward in time, she explains the celebrity sheep's links to the embryonic cell lines and global bioscientific innovation of the late twentieth century and early twenty-first.

Franklin combines wide-ranging sources—from historical accounts of sheep-breeding, to scientific representations of cloning by nuclear transfer, to popular media reports of Dolly's creation and birth—as she draws on gender and kinship theory as well as postcolonial and science studies. She argues that there is an urgent need for more nuanced responses to the complex intersections between the social and the biological, intersections which are literally reshaping reproduction and genealogy. In Dolly Mixtures, Franklin uses the renowned sheep as an opportunity to begin developing a critical language to identify and evaluate the reproductive possibilities that post-Dolly biology now faces, and to look back at some of the important historical formations that enabled and prefigured Dollys creation.
