The Institute won international fame in 1996, when Ian Wilmut, Keith Campbell and their colleagues created Dolly the sheep, the first mammal to be cloned from an adult cell, at the institute. A year later Polly and Molly were cloned, both sheep contained a human gene. Roslin has made many other contributions to animal sciences, especially in the area of livestock improvement and welfare through applications of Quantitative Genetics. In 2007 a Roslin team developed genetically modified chickens capable of laying eggs containing proteins needed to make
Marine mammal University of Pittsburgh showed that the ancestors of many marine mammals stopped producing a certain enzyme that today protects against some neurotoxic chemicals called organophosphates, including those found in the widely used pesticides chlorpyrifos and diazinon.
