Which other mammals have been cloned since Dolly the sheep?
Following the successful cloning of Dolly in 1996 via somatic cell nuclear transfer (SCNT), scientists have utilized the same technique to clone a variety of other mammals. These include:
Additionally, in 2018, researchers announced the first live birth of primate clonesâtwo crab-eating macaquesâusing the SCNT process.1
It is important to note that reproductive cloning is considered highly problematic from an ethical and scientific standpoint. The process is often harmful, as SCNT-cloned embryos frequently fail to survive gestation and are often born with severe birth defects. Given these significant risks to the welfare of the animals involved, the practice raises profound ethical concerns regarding the treatment of living beings and the morality of experimental manipulation.2
