On the Trail of the Jackalope - Michael P Branch - Bog

"Purported to be part jackrabbit and part antelope, the jackalope began as a local joke concocted by two young brothers in a small Wyoming town during the Great Depression. Their creation quickly spread around the U.S., where it now regularly appears as innumerable forms of kitsch ... Although the jackalope is an invention of the imagination, it is nevertheless connected to actual horned rabbits, which exist in nature and have for centuries been collected and studied by naturalists. Around the time the two young boys were creating the first jackalope in Wyoming, Dr. Richard Shope was making his first breakthrough about the cause of the horns: a virus. When the virus that causes rabbits to grow 'horns' (a keratinous carcinoma) was first genetically sequenced in 1984, oncologists were able to use that genetic information to make remarkable, field-changing advances in the development of anti-viral cancer therapies"--Publisher's website.
