She was discovered in a ghost town in the Atacama Desert in South America. Her tiny skeleton was found in a pouch. She was a 6-inch-long, fully formed female skeleton. She had 10 ribs (normal amount is 12) and an elongated skull. She was a perfectly formed miniature human. Was she an alien? Many believed she could be or a human alien hybrid. Was she a primate? They called her the Atacama skeleton and she was featured in the alien documentary Sirius where they asked the same questions. She was later sold to a collection in Spain.
The skeleton raised many questions and the scientists were keen on treating her with respect as they went about trying to get answers. The first thing to do was to analyze her DNA, “1 mm3 of bone was removed from the skeleton in Spain by the Sirius team, flown to the United States by a member of that team, and provided to Dr. Nolan.” (Nolan, 2018)
Ralph Lachman, Co-director of the International Skeletal Dysplasia Registry at Cedars-Sinai Medical Center in Los Angeles, California was quoted saying, “Wow, this is like nothing I've ever seen before." (Stone, 2013) Upon investigation, the DNA revealed she was human. Her mitochondrial testing revealed her mother was a woman from west coast of South America. The skeleton’s quality of DNA suggested that it was decades old.
Her bone density and the epiphyseal plates of the knees are equivalent to a 6-8-year-old child. It means she was born that tiny or had some bone disease that made it appear her age was older than she was. Many believed the results of the DNA testing shot down the theory of the skeletal remains being alien. It really brought up more questions than it answered.
If you are a believer in aliens, this really did not rule out a possible origin from another race. It could be her father was alien or that the race was closely related to human DNA. The many theories really do not answer the question of where she came from or what were her skeletal issues. The Genome research had this to say, “This was a girl with many DNA mutations, not anything more exotic. Further functional studies of these alterations may lead to a clearer understanding of the genes that regulate bone development.” (Nolan, 2018) So all the declaring it is human therefore, not alien really have not disproven the exotic nature. They only speculate, the same thing they chastise the UFO community for doing.
