There has been some more stem cell research since then...
The person who cloned dolly was a scientist named Ian Wilmut, with Keith Campbell, however he had a team who helped him to create dolly in Edinburgh. Dolly was about 6 1/2 years old at the time they had to put her down from developing a disease, and arthritis in her hind legs.
Cloning has been a topic of scientific interest for decades, with the first successful cloning of a mammal (Dolly the sheep) in 1996. Since then, cloning technology has advanced, leading to the cloning of other animals and ongoing ethical debates surrounding the practice. Cloning has potential benefits for research and medicine but also raises concerns about ethical implications and the impact on biodiversity.
Natural cloning has been around as long as humans. When a fertilized egg splits to create two or more identical embryos a clone is created. We refer to those clones as "twins" or "triplets", etc. Humans first cloned a sheep in the year 1996. Since then speculation about the viability of artificially cloning a human has been hotly debated but no one has shown any verifiable success. The technology exists to make it a possibility, so it is likely that some laboratories have made serious attempts or will at some time in the near future.
Cell cloning is using DNA or RNA within cells to produce life. This is considered immoral and unethical in many medical circles. Whole organism cloning, however, is considered more acceptable since they are dealing with whole and no partial organisms.
Growing tissues or organs from cloned embryonic stem cells for transplantation holds significant potential, but it also raises safety and ethical concerns. While cloned stem cells can potentially reduce the risk of rejection since they are genetically identical to the donor, issues such as tumor formation, immune response, and the long-term viability of the tissue remain critical challenges. Additionally, ethical considerations surrounding cloning practices and the source of embryonic stem cells complicate the acceptance of this approach. Ongoing research is essential to address these safety and ethical concerns before widespread clinical application.
Cloning is not very common as of now, and I don't believe it's been tested on humans since it is not deemed safe enough. However, Dolly the sheep was the first to be cloned, and it made her life miserable.
== == * Since the cloning of the sheep Dolly having acquired a break down of cells and had to be euthanize at age 6 when she should have lived to be 12 years or more there have been dogs, cats and and even a mule (used for racing) cloned, but the facts about cloning have been kept very low key and for good reason. There is more cloning going on then most of us know and there is good reason to believe that some cloned and butchered animals are in our pet's food, so how do we know we aren't getting some of this food. Cloning is not a perfected science and can cause disease or newer diseases. Pig's skin and even some organs have been used on humans for transplants. There is a hush about cloning because although cloning of a human organ would be a wonderful thing and more people would get organs instead of left on waiting lists there is a bad side to this as well .... the break down of cells and what other diseases this could cause in humans. One shouldn't play God with such things (or fool Mother Nature) but cloning is going on all over the world and it's bound to come and stay regardless of the dangers. * The answer is, after the first cloned animal in 1952, a tadpole, there has been a number of clones, so many were made in the same time so there really is no second animal cloned, there are hundreds. * While it is possible there were other cloned animals before 'Dolly' it would have been illegal at that given time and the scientific study of cloning is 'Dolly!'
Science has made significant advancements in cloning, particularly in the cloning of animals. The first cloned mammal, Dolly the sheep, was born in 1996. Since then, scientists have successfully cloned various other animals, but human cloning remains ethically and legally prohibited in most countries.
Dolly the Sheep was named after Dolly Parton because the cell that was taken from the sheep to clone Dolly the sheep was a mamary gland cell, since Dolly Parton is known for her boobs Dolly was the natural choice.
Numerous research studies have been conducted on cloning, with the most notable success being the cloning of Dolly the sheep in 1996. Since then, other animals such as cats, dogs, and monkeys have also been cloned. Cloning research continues to advance, with ongoing attempts to improve efficiency and address ethical concerns.
Yes, scientists have successfully cloned animals such as sheep, cows, pigs, and mice. The most famous cloned animal is Dolly the sheep, who was cloned in 1996. Cloning technology has advanced since then and has been used for various research purposes.

Cloning has been around since the 1950s, with the first successful cloning of a sheep named Dolly taking place in 1996. Since then, advancements in cloning technology have been made, leading to the cloning of various animals for research and conservation purposes.

1951 was when the first successful clone of a frog egg was created, though some early attempts at cloning in the 1800's were made. Hans Dreisch was the man in the late 1800's to conduct attempts at cloning a sea urchin.Although the cloning on non-mammals was first accomplished way back in 1952, the world had to wait for another 44 years before the first mammal was finally cloned. The first cloned mammal, a sheep named Dolly was born on 5th July 1996. The birth of Dolly had established the ability of we humans to clone mammals. And being mammals themselves, this was an important milestone for the human race. In this fascinating history of cloning, a major setback came in 2003 when Dolly died at the age of six. The death of this first cloned mammal was followed by an intense debate, about the ethical issues of cloning, which continues even today.A Brief History of CloningCloning is basically the process by which a genetically identical copy of a particular bacteria, plant or animal is produced by asexual reproduction. The term 'clone', was coined by J.B.S. Haldane, an eminent Scottish biologist, in his speech entitled Biological Possibilities for the Human Species of the Next Ten-Thousand Years in 1963. The history of cloning can be traced back to 1880s, when many scientists attempted to prove how the genetic material inside the cells worked. Whilst trying to prove that the genetic material is not lost during cell division, Hans Dreisch cloned sea urchins by separating two cells and growing them independently. In 1902, Hans Spemman repeated the same process with a salamander.History of Cloning PlantsIt is very difficult to trace the timeline of cloning plants, owing to the fact that such cloning of plants has been practiced by humans, since thousands of years, and by the nature, for a longer time. Interestingly enough, there have been quite a few citations about cloning of plants in the cloning history. One such example being the cloning of a full carrot by F. C. Stewart in 1964.The History of Animal CloningThe first successful animal cloning experiment was executed by Robert Briggs and Thomas J. King, when they cloned northern leopard frogs in 1952. In 1962, John Gurdon used the nucleus of fully differentiated adult intestinal cells and cloned South African frogs, thus proving that a cell's genetic potential doesn't diminish as the cell specializes. In 1963, the Chinese embryologist Tong Dizhou cloned the first fish, by inserting the DNA from a cell of a male into the egg of a female. A major breakthrough in the attempts to clone animals came in the form of cloning of Dolly, the sheep, by Ian Wilmut, Keith Campbell and other scientists from the Roslin Institute in Scotland. Since then several other animals, ranging from cat and dog species to camel and Water-buffalo species have been cloned successfully. In 2009, an extinct animal species - the Pyrenean Ibex was cloned, however, it only survived for 7 minutes before becoming extinct again.History of Human CloningOther than the successful attempts at cloning various animal species, the 20th century was also marked by some of the major advancements in the field of genealogy. The successful deciphering of the DNA code in 1968 came as a major boost for the much aspired human cloning. Around 20 years later, in 1988, the Human Genome, i.e. the genome of Homosapiens stored in 23 chromosome pairs, was launched. As things were working fine towards the development of a human clone, a major setback came in the form of the Human Cloning Prohibition Act of 2009, which deemed cloning as unlawful, unethical and an immoral activity. The opposition to cloning of humans came from scientific community, who were not satisfied with the results of animal cloning, as well as the religious community, which regarded human cloning to be an activity interfering with human life and procreation.This was a brief history of cloning, spanning over a period of around 120 years. As of 2009, human cloning is considered to be illegal in 23 countries. The fraternity of pro-cloning scientists and researchers are hoping that human cloning is legalized soon, after which they can get back to their labs, and continue experiments related to the same.

When there is no variation at all, can you imagine all people are just the same. and also when there is an epidemic , since all of the cloned species is the same, all species may died and resulted in extinction.
it is carried out to see if the product works and can be okay if they use it on humans. If it will affect them or not basically. It is a science technique because it helps people live and create good remedies that can be okay to use!
