What archaeology says
Peru's scientific and legal institutions have been unambiguous. In 2017-2018 the World Committee on Mummy Studies called the affair an 'irresponsible organised campaign of disinformation' and a likely crime against the dead, noting the larger bodies appear to be genuine pre-Columbian mummies mutilated for the purpose. A Peruvian prosecutor-office report concluded early specimens were 'recently manufactured dolls' covered with paper and synthetic glue to simulate skin, and in January 2023 the Institute of Forensic Legal Medicine examined two small 'mummies' seized at Lima airport, finding one skull came from a quadruped mammal and the bodies were assembled from bird and animal bones with modern glue. In 2024, forensic archaeologist Flavio Estrada of the Public Ministry presented findings on 'Maria'-type bodies bluntly: dolls made of animal bones, paper and glue — 'the claim they are extraterrestrial is totally false'.
Independent specialists agree on the anatomy: the tridactyl hands and feet show mismatched bone counts, duplicated and reversed phalanges consistent with cut-and-paste reassembly from human hands and feet; the elongated skulls match well-known Andean cranial modification or, in small specimens, animal braincases. The much-cited DNA runs show degraded, contamination-heavy mixtures — substantially human plus bacterial and unidentifiable reads, which is what damaged, handled remains yield; 'unknown DNA' percentages reflect sequencing noise, not new species.
For archaeologists the affair is looting and desecration: real Nazca-region human remains, protected by law, have been cut apart to manufacture spectacle, and UNESCO-linked and university voices in Peru have demanded repatriation and prosecutions. UNAM's radiocarbon laboratory, whose dates Maussan cited, publicly disavowed any endorsement of the bodies' interpretation.
- Peru's Institute of Forensic Legal Medicine found airport-seized specimens were assembled from bird and mammal bones with modern synthetic glue
- Forensic archaeologist Flavio Estrada's 2024 report identified the bodies as manufactured dolls using animal and human remains, paper and glue
- Anatomical reviews show duplicated, reversed and miscounted phalanges in the 'tridactyl' hands, consistent with reassembly from human parts
- The World Committee on Mummy Studies condemned the affair as organised disinformation and desecration of real pre-Columbian mummies
- UNAM's radiocarbon laboratory disavowed use of its dates to support non-human claims; dating tissue does not date an assemblage
- DNA results show degraded human sequences plus contamination — the profile of manipulated ancient remains, not a new species
