Panda once thought to be male gives birth to twins

BEIJING (AP) - A panda once mistakenly thought to be male has given birth to twins, a news report said Thursday.
Jinzhu delivered twin female cubs Monday night at the Wolong Nature Reserve for Giant Pandas in southwestern China, the Xinhua News Agency said. It said the 11-year-old panda was in critical condition after hemorrhaging.
Jinzhu was mistakenly classified as a male at birth in 1996, according to Xinhua.
Scientists realized the mistake only after Jinzhu was sent to Japan in 2000 to mate with a female panda, the report said.
The animals "showed complete disinterest" in mating, "leading to the discovery that Jinzhu had no penis," Xinhua said.
