In H. G. Wells's The Island of Doctor Moreau, written in 1896, the hero confronts Dr. Moreau's various animal-human hybrids. These 'chimeras' were literally the stuff of legend. No longer. Chimeras have emerged kicking and mewling in labs across the world. They included a goat-sheep chimera, dubbed a geep. The animal was striking to see, a patchwork of wool and coarse hair. The goal is to produce human body parts in animals for human transplant. God Help Us.
