Dolly the sheep's birth was perhaps the greatest moment in the history of the world for cloning advocates.  Dolly was born in 1997 after years of research and effort.  Dolly received momentous media coverage as she was the first scientifically documented mammal cloned.  Despite being "conceived" in a laboratory, Dolly gave birth to 6 lambs during her life.  While most Finn Dorset sheep have a normal life span of 11 years, Dolly was taken from us on February 14, 2003 after only 6 years of life (2).  Though Dolly died of arthritis and lung cancer over three years ago, her legacy will be remembered forever (picture is reference 7).
 

   In 2001, another scientific miracle was born.  Noah, a gaur or endangered breed of ox, was born to an Iowa cow despite being cloned from ancestors living in Indochina and southeast Asia.  This scientific feat has encouraged further testing in cloning endangered species and for cloning different species within other animals.  Though Noah died of a common bacterial infection, testing of this kind will continue far into the future (8, picture is reference 9).

                                                            
                                       

    Pieraz-Cryozootech-Stallion, also known as "Pieraz 2", is the first ever clone of a champion endurance racehorse, bred to preserve its prize-winning genes.  Born in 2003, Pieraz 2 is a genetic copy of the original Pieraz, an endurance racehorse who was world champion in 1994 and 1996. The original Pieraz was castrated at the age of three and as a result, could not father any foals. Showjumping, eventing, polo, and other endurance races are dominated by geldings (Arab horse), which are by definition infertile. The castration process is a common practice for competing horses. Today Pieraz 2's designer is hopeful that once he is old enough to breed, his "champion genes" can be passed down to further generations (21, picture is reference 21).
