Perhaps the greatest polo player ever, Adolfo Cambiaso is planning to compete on a pony that died nearly a decade ago—a clone of his beloved stallion Aiken Cura. With more than 25 replicas of champion horses now in existence, Haley Cohen explores how the science came to polo. ... Aiken Cura is one of a number of horses that Cambiaso has duplicated. Through their company, Crestview Genetics, Cambiaso and two wealthy polo enthusiasts—the founder, Texan Alan Meeker, and Argentinean tycoon Ernesto Gutiérrez—have created more than 25 clones of Cambiaso’s champion polo horses and around 45 clones in total. Some are already breeding, and a few others began to play in top tournaments last year. Since the company’s establishment, in 2009, the partners have cloned not only for themselves but also for other international polo players who are willing to shell out around $120,000 per horse. Crestview is one of only two commercial groups in the world replicating polo horses, and it is the more prolific. ... Cloning began long before the world started paying attention to it, in 1996, when Dolly the Sheep, the first mammal successfully cloned from an adult cell, clomped into the world. One hundred years before, in 1885, Hans Driesch created two identical sea urchins by jiggling a two-celled urchin embryo until the cells separated and grew into their own creatures. Through much more sophisticated processes, scientists have since cloned pigs, cows, dogs, cats, ferrets, goats, and horses. (It is estimated that there are now around 300 cloned horses in the world, although no one has really kept track.) Now, with Crestview’s efforts, polo—the ancient “game of kings”—has found itself on the frontiers of cloning technology. ... “I did the math and realized it would take me $100 million and 50 years to get the quality of horses I wanted through conventional breeding,” he says. “I decided I didn’t want to spend either.” Instead, he turned to cloning.
