When was the first mammal cloned?

Dolly the sheep was born in July 1996 at the Roslin Institute in Scotland, and her birth was announced to the public in 1997. She was the first mammal cloned from an adult somatic cell, using a technique called somatic cell nuclear transfer. Dolly’s creation showed that specialized adult cells could be reprogrammed to develop into a complete animal. Her birth became a landmark in genetics and biotechnology.
