Introduction
Scientists have been able to bring back endangered animals all over the world thanks to cloning. Many people around the world feel that this is what needs to be done in order to bring an endangered species back to a growing population. The possibility of cloning endangered species back to a sufficient population is also very real, thanks to the gigantic frozen cell collection at San Diego's Zoo's Center for Reproduction of Endangered Species. With all of these animals cells, scientists are able to clone any animal in that collection.
The first cloned endangered animal was a Gaur named Noah. A Gaur is a member of species of large ox like animals that are rare in their homelands of India. They have been hunted for sport for generations.
How does it Work
The first experiment on animal cloning was done by Robert Briggs and Thomas King on a common grass frog. They extracted the nucleus from an unfertilized egg cell by inserting fine glass tube into the cytoplasm. Than, a nucleus from a frog embryo in the early stages of development was extracted and then insterted into the enucleated cell. Much like any normal fertilized egg cell, the cell with the transplated nucleus began to divide and it grew into an adult
