Cloning is the process of producing individual organisms with identical or virtually identical DNA, either by natural or artificial means. In nature, some organisms produce clones through asexual reproduction. In the field of biotechnology, cloning is the process of creating cloned organisms (copies) of cells and of DNA fragments.
Dolly was a female Finn-Dorset sheep and the first mammal that was cloned from an adult somatic cell. She was cloned by associates of the Roslin Institute in Scotland, using the process of nuclear transfer from a cell taken from a mammary gland. Her cloning proved that a cloned organism could be produced from a mature cell from a specific body part. Contrary to popular belief, she was not the first animal to be cloned.
Human cloning is the creation of a genetically identical copy of a human. The term is generally used to refer to artificial human cloning, which is the reproduction of human cells and tissue. It does not refer to the natural conception and delivery of identical twins. The possibilities of human cloning have raised controversies. These ethical concerns have prompted several nations to pass laws regarding human cloning.
An embryo is an initial stage of development of a multicellular organism. In organisms that reproduce sexually, embryonic development is the part of the life cycle that begins just after fertilization of the female egg cell by the male sperm cell. The resulting fusion of these two cells produces a single-celled zygote that undergoes many cell divisions that produce cells known as blastomeres. The blastomeres are arranged as a solid ball that when reaching a certain size, called a morula, takes in fluid to create a cavity called a blastocoel. The structure is then termed a blastula, or a blastocyst in mammals.
In genetics and developmental biology, somatic cell nuclear transfer (SCNT) is a laboratory strategy for creating a viable embryo from a body cell and an egg cell. The technique consists of taking an enucleated oocyte and implanting a donor nucleus from a somatic (body) cell. It is used in both therapeutic and reproductive cloning. In 1996, Dolly the sheep became famous for being the first successful case of the reproductive cloning of a mammal. In January 2018, a team of scientists in Shanghai announced the successful cloning of two female crab-eating macaques from foetal nuclei.
The macaques constitute a genus (Macaca) of gregarious Old World monkeys of the subfamily Cercopithecinae. The 23 species of macaques inhabit ranges throughout Asia, North Africa, and Europe. Macaques are principally frugivorous, although their diet also includes seeds, leaves, flowers, and tree bark. Some species, such as the crab-eating macaque, subsist on a diet of invertebrates and occasionally small vertebrates. On average, southern pig-tailed macaques in Malaysia eat about 70 large rats each per year. All macaque social groups are matriarchal, arranged around dominant females.
SeaWorld is an American theme park chain with headquarters in Orlando, Florida. It is a proprietor of marine mammal parks, oceanariums, animal theme parks, and rehabilitation centers owned by SeaWorld Parks & Entertainment. The parks feature orcas, sea lion, and dolphin shows and zoological displays featuring various other marine animals.
Commercial animal cloning is the cloning of animals for commercial purposes, currently, including livestock, competition camels and horses, pets, medical uses, endangered and extinct animals, as first demonstrated in 1996 for Dolly the sheep.
WTOC-TV is a television station in Savannah, Georgia, United States, affiliated with CBS and owned by Gray Television. The station's studios are located off Chatham Center Drive in Savannah's Chatham Parkway section, and its transmitter is located along Fort Argyle Road/SR 204 in unincorporated Chatham County.
Snuppy was an Afghan hound, the first dog clone. The puppy was created using a cell from an ear from an adult Afghan hound and involved 123 surrogate mothers, of which only two produced pups. The Department of Theriogenology and Biotechnology at Seoul National University, which cloned Snuppy, was led by Woo Suk Hwang. Snuppy has since been used in the first known successful breeding between cloned canines after his sperm was used to artificially inseminate two cloned females, which resulted in the birth of 10 puppies in 2008. In 2017, 4 clones of Snuppy were made by Sooam, and were the first clones made of a cloned dog, to investigate potential health effects of cloning.

In bioethics, the ethics of cloning refers to a variety of ethical positions regarding the practice and possibilities of cloning, especially human cloning. While many of these views are religious in origin, some of the questions raised by cloning are faced by secular perspectives as well. Perspectives on human cloning are theoretical, as human therapeutic and reproductive cloning are not commercially used; animals are currently cloned in laboratories and in livestock production.
Jurassic Park, later also referred to as Jurassic World, is an American science fiction media franchise created by Michael Crichton and centered on a disastrous attempt to create a theme park of cloned dinosaurs. It began in 1990 when Universal Pictures and Amblin Entertainment bought the rights to Crichton's novel Jurassic Park before it was published. The book was successful, as was Steven Spielberg's 1993 film adaptation. The film received a theatrical 3D re-release in 2013, and was selected in 2018 for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant". A 1995 sequel novel, The Lost World, was followed by a film adaptation in 1997. Subsequent films in the series, including Jurassic Park III (2001), are not based on the novels.
A frozen zoo is a storage facility in which genetic materials taken from animals are stored at very low temperatures (−196 °C) in tanks of liquid nitrogen. Material preserved in this way can be stored indefinitely and used for artificial insemination, in vitro fertilisation, embryo transfer, and cloning. Some facilities also collect and cryopreserve plant material.
Elanco Animal Health Incorporated is an American pharmaceutical company which produces medicines and vaccinations for pets and livestock. Until 2019, the company was a subsidiary of Eli Lilly and Company, before being divested. It is the third-largest animal health company in the world.
