Alien? Subhuman primate? Deformed child? Mummified fetus? The Internet is buzzing over the nature of "Ata," a bizarre 6-inch-long skeleton featured in a new documentary on UFOs. A Stanford University scientist who boldly entered the fray has now put to rest doubts about what species Ata belongs to. But the mystery is not over.

The story began 10 years ago, when the diminutive remains were reportedly found in a pouch in a ghost town in the Atacama Desert of Chile. Ata ended up in a private collection in Barcelona; producers of the film Sirius latched onto the bizarre mummy as evidence of alien life.

Last fall, immunologist Garry Nolan, director of the National Heart, Lung, and Blood Institute's Proteomics Center for Systems Immunology at Stanford in California, heard about Ata from a friend and contacted the filmmakers, offering to give them a scientific readout on the specimen. They asked him to give it a shot.

Among the apparent abnormalities, Ata sports 10 ribs instead of the usual 12 and a severely misshapen skull. "I asked our neonatal care unit how you would go about analyzing it. Had they seen this kind of syndrome before?" Nolan says. He was directed to pediatric radiologist Ralph Lachman, co-director of the International Skeletal Dysplasia Registry at Cedars-Sinai Medical Center in Los Angeles, California. "He literally wrote the book on pediatric bone disorders," Nolan says. Lachman was blown away, Nolan recalls: "He said, 'Wow, this is like nothing I've ever seen before.' "

The fact that this is a completely unique mutation NEVER previously observed, makes this case very intriguing.  To read more, click here.
