Sheep ideal research subjects, and thus are not a common model organism. They have, however, played an influential role in some fields of science. In particular, the Roslin Institute of Edinburgh, Scotland used sheep for genetics research that produced groundbreaking results. In 1995, two ewes named Megan and Morag were the first mammals cloned from differentiated cells. A year later, a Finnish Dorset sheep named Dolly, dubbed "the world's most famous sheep" in "Scientific American", was the first mammal to be cloned from an adult somatic cell. Following this, Polly and Molly were the first mammals to be simultaneously cloned and
The Marine Mammal Center is unregulated and results in seizures. Repeated exposure will cause repeated activation, ultimately burning out these neural pathways and causing permanent brain damage; specifically, atrophy of the hippocampus. Domoic acid is the same biotoxin that causes amnesic shellfish poisoning in humans. Another discovery by the Marine Mammal Center, in collaboration with the University of Florida, is that seal pox is distinct from pox viruses isolated from other species. It is unrelated to chicken pox or smallpox. Also being investigated is the increased incidence of leptospirosis, a bacterial pathogen that can acutely damage the kidneys of marine mammals.
