The six-inch-long skeleton , nicknamed “Ata,” was found in Chile’s Atacama Desert in 2003. Speculation regarding the remains has been intense among ancient alien proponents ever since.
While some said the small skeleton was probably that of a primate or perhaps a human fetus, other theorized that the tiny elongated skull and ribcage containing only ten ribs, instead of the usual 12, was proof that an extraterrestrial had crash-landed on Earth.
“While the jury is out regarding the mutations that cause the deformity, and there is a real discrepancy in how we account for the apparent age of the bones … every nucleotide I’ve been able to look at is human,” Garry Nolan, professor of microbiology and immunology at Stanford School of Medicine, told LiveScience.
“I’ve only scratched the surface in the analysis. But there is nothing that jumps out so far as to scream ‘nonhuman,’” he said.
The research team also tried to find out what caused Ata’s deformities, but were unable to reach a conclusion.
“It’s an interesting medical mystery of an unfortunate human with a series of birth defects that currently the genetics of which are not obvious,” Nolan said.
Ata and the team’s research was featured in film “Sirius,” a crowd-funded documentary that premiered on April 22 in Hollywood, Calif.
