Dolly the Sheep was the first mammal to be cloned from an adult somatic cell, created by scientists at the Roslin Institute in Scotland in 1996. She was cloned using a technique called somatic cell nuclear transfer, where the nucleus of an adult cell was inserted into an egg cell that had its nucleus removed. Dolly was born on July 5, 1996, and her birth marked a significant milestone in the field of genetics and biotechnology. Dolly lived for six and a half years and gave birth to several lambs. Her creation raised ethical questions about cloning and its implications for animal welfare and human genetics. Dolly was euthanized in 2003 due to a progressive lung disease, and her legacy continues to influence discussions on cloning and genetic research.
