Cloning is the creation of an exact genetic copy of a living thing through artificial embryo twinning or somatic cell nuclear transfer. Cloning technologies have been used to clone animals like Dolly the sheep to improve livestock and save endangered species. Some believe human cloning could have therapeutic uses, while others argue that cloning goes against the principle that God alone has the power of creation.
