From Breitbart news: "Two qualifying heats, two wire-to-wire victories, two nearly identical times. It was almost like the same mule won twice. Idaho Gem, the world's first equine clone, and his brother, Idaho Star, made successful debuts Saturday in what scientists billed as the first professional competition between clones of any kind."
UPDATE 6/5: Looks like the horses didn't win in the final race on Sunday, coming in 3rd and 7th. No matter, it's fascinating (and a little unnerving) to see genetically engineered animals competing in a very traditional sport.
