Cloned Animals

This list showcases some of the notable animals that have been successfully cloned over the past thirty years, illustrating the remarkable development and expansion of cloning technology since Dolly the sheep’s breakthrough in 1996. While it is not comprehensive, the list highlights key milestones across various species, from farm animals to endangered species and pets, reflecting both scientific progress and ongoing ethical questions. The examples here serve to inform and inspire further discussion about cloning’s possibilities and challenges. The rate of failure is calculated by examining the number of successfully produced clones versus the number of implanted embryos. It does not take into account the total number of embryos produced.
