The most famous sheep in human history, Dolly the sheepwas the world’s first cloned mammal created from adult cells. It took 276 attempts and a lot of effort to create Dolly, and the famous sheep became a major scientific milestone, appearing in newspapers and magazines around the world.
Dolly was born to a surrogate ewe in July 1996 and spent most of her life at the Roselin Institute in Scotland. Although her anatomy was extensively studied, she lived a largely normal life for a sheep. Dolly was even allowed to mate with a ram, giving birth to six lambs: Bonnie, Sally, Rosie, Lucy, Darcie and Cotton.
However, Dolly’s body had many health problems and she could not live to the age of 12 like normal sheep. Dolly’s additional clones, formed from “same cell line” later proved much more successful, proving once and for all that Cloning can produce normal, healthy animals, theo The Washington Post.
In the 1950s, biologist John Gurdon of Oxford University in England discovered How to clone Xenopus laevis. Since then, scientists have made similar attempts to recreate one organism genetically identical to another. Researchers have tried everything from frogs to toads to fish, but this has been impossible, if not nearly impossible, for large mammals at the time. (Photo: Grunge).
The Short Life of Dolly the Sheep
Within just a few short years of her birth, Dolly the sheep died – despite Its body was donated to the National Museum of Scotland to be displayed. Even if you can’t make it to Scotland, you can still view a 3D digital model of Dolly on the museum’s website.
As mentioned earlier, Dolly’s life was cut short by health issues. In 2000, Dolly was diagnosed with JSRV, a disease that causes lung cancer in sheep. At the age of five, she suffered from severe osteoarthritis of unknown cause. While her arthritis was treatable, the tumors that developed in her lungs were not. At the age of six, Dolly was put to sleep (euthanized) on Valentine’s Day 2003.
