Bathed in violet light, two men search the white expanse of cloth, oblivious to their surroundings. Disoriented insects of various shapes and sizes swoop around the men’s heads. Many of the insects eventually land on the sheet. With a deft motion, one of the men captures a specimen and examines the vial in which a pale-colored moth flutters.
The University of Arizona Genetics Core (UAGC), located in the Thomas W. Keating Bioresearch Building on the UA campus, is home to rows of rectangular machines that hum busily at all hours of the day and night. These machines, with names like Illumina HISEQ 2000 and Ion Torrent, are the inanimate workhorses of the UAGC, producing hundreds of thousands of pieces of data in a single run.
With a mischievous grin and gleaming dark eyes, Dr. Dragos Zaharescu raises a small spatula to his lips and tastes. At his feet are four containers, each filled with a different type of ground rock—granite, basalt, rhyolite or schist. Zaharescu will blend this rock with bacteria or fungus, creating a sandy medium for seedlings he grows here under the glass dome of Biosphere 2.
On May 12, 2011, Arby and Pat Little Soldier of Lakota Ranch near Greenville, Texas, rejoiced over the birth of a rare white buffalo calf, named Lightning Medicine Cloud. The white buffalo, more accurately called a bison (Bison bison), has long been a symbol of Native American spirituality, hope and rebirth.

What are the chances that another white bison calf will be born any time soon? The National Bison Association estimates that only one out of 10 million births results in a white calf. While the genetics of white bison are not fully understood, four mechanisms are possible.
