# The elongated Paracas skulls from Peru are a non-human or alien species

**Verdict: Contradicted.** The roughly 300 Paracas skulls are genuine ancient human remains whose elongated shape comes from artificial cranial deformation, a well-documented Andean practice of binding infants' heads. The 'non-human DNA' claim began as a 2014 Facebook announcement by an Ancient Aliens tour promoter, never as peer-reviewed science, and later sampling recovered too little usable DNA for any firm conclusion.

## Summary
Excavated from Peru's Paracas necropolis in 1928, these dramatically elongated skulls are sometimes presented as proof of a non-human species: aliens, or an unknown hominin, supposedly confirmed by DNA that 'doesn't match' any human. The skulls are real and genuinely striking. They are also, on the evidence of anthropology and the practitioners' own contradictory DNA claims, ordinary human skulls reshaped by intentional cranial binding, a practice documented across the ancient Andes and much of the world.

## The claim
That the roughly 300 elongated skulls excavated from Peru's Paracas necropolis are not ordinary humans but a separate species (extraterrestrial visitors or an unknown hominin), and that DNA testing has proven their genetic material does not match Homo sapiens.

## Origin and timeline
- c. 800 BCE – 100 BCE: The Paracas culture flourishes on Peru's southern desert coast, leaving behind elaborate textiles, mummy bundles and, among its elite, deliberately elongated skulls. Like many Andean peoples, the Paracas practice artificial cranial deformation, reshaping infants' heads before the bone hardens.
- 1928: Peruvian archaeologist Julio Tello excavates a large necropolis on the Cerro Colorado headland at Paracas and uncovers more than 300 elongated skulls, some roughly 3,000 years old: the largest concentration of such skulls found anywhere.
- 20th century: Anthropologists studying skulls from Paracas and dozens of other cultures worldwide establish artificial cranial deformation as the standard, well-evidenced explanation for elongated crania, produced by binding the head with cloth, cord or boards in the first years of life.
- 2000s–2010s: Brien Foerster, a tour operator and recurring guest on the History Channel's Ancient Aliens, popularizes the Paracas skulls as an unsolved mystery, working with a privately run Paracas History Museum rather than an academic institution.
- 2014-02: Foerster announces preliminary DNA results: an unnamed geneticist supposedly found mutations that match no known species and do not appear in the GenBank database. The 'results' are released on Facebook and blogs, not in any peer-reviewed journal, and the tester's identity is never disclosed.
- 2014 onward: Ancient Aliens and a web of pseudo-archaeology sites amplify the 'non-human DNA' claim, folding the skulls into the broader ancient-astronaut narrative already attached to Peru's Nazca Lines.
- 2018: A further, still non-peer-reviewed round of DNA sampling is promoted as showing unusual maternal-line (mitochondrial) ancestry linked to European or Near Eastern populations. Even on its own terms this points to human beings, not aliens, and it quietly contradicts the earlier 'not human at all' announcement.
- 2010s–2020s: Attempts to sequence ancient DNA from the skulls repeatedly run into the basic problem of degraded, contaminated samples with too little usable genetic material to support firm conclusions, while anthropologists reaffirm the remains as fully human and artificially shaped.

## The evidence, claim by claim
- Claim: The skulls are too large and too heavy to be explained by head-binding: they have greater cranial volume than a normal human skull, so the shape must be genetic, from a separate species.
  Evidence: This is the central factual error. Artificial cranial deformation redistributes the growth of the skull without adding brain tissue; it changes the shape, not the person's species. The larger-volume figures come from promoters, not from independent morphologists, and they overlook the ordinary range of human skull size. Cut surfaces, sutures and bone structure on the Paracas crania are those of Homo sapiens, matching deformed skulls documented in many other cultures.
- Claim: DNA testing revealed mutations that match no known species and are absent from GenBank.
  Evidence: The 2014 announcement failed every basic test of credibility. It was made on Facebook by a tour operator with no relevant scientific training, the geneticist was never named, and no data or method was published for review. Where ancient DNA from such samples can be read at all, it is degraded and contaminated; an 'unknown' fraction is the hallmark of a poor sample, not of a new branch of life. No peer-reviewed genome supporting a non-human origin has ever appeared.
- Claim: A later DNA round showed the skulls came from a mysterious foreign population, proving they are not local humans.
  Evidence: Taken at face value, foreign human ancestry is still human ancestry, which refutes rather than supports the 'alien species' claim. But even that result was announced outside peer review, drawn from small, contamination-prone samples, and it openly contradicted the earlier 'not human' story. Two incompatible unverified claims from the same promoters cannot both be the smoking gun.
- Claim: Features like extra foramina, unusual sutures or reddish hair on the skulls cannot be human.
  Evidence: Each of these occurs in ordinary humans. Reddish hair on ancient remains reflects pigment degradation and burial chemistry; variation in the small openings and sutures of the skull is normal human anatomy. None of it distinguishes a new species, and anthropologists who have examined the crania read every such feature as human.
- Claim: Mainstream science refuses to seriously test the skulls, which is why the mystery persists.
  Evidence: The reverse is true: cranial deformation is one of the most thoroughly studied practices in physical anthropology, documented from Paracas to Tiwanaku to Neolithic Eurasia. Scientists have not ignored the skulls; they have identified what they are. What has never been produced is a rigorous, published study supporting the alien claim, despite years of opportunity.

## Why people believe it
- The skulls are genuinely startling to look at. An elongated cranium reads instantly as 'other', and the visual shock does a lot of persuasive work before any evidence is weighed.
- The claim slots neatly into the ancient-astronaut narrative already attached to Peru, especially the Nazca Lines, so a strange skull from the same region arrives pre-loaded with meaning.
- A confident presenter on a long-running cable series lent the story the visual grammar of research: museum specimens, DNA charts and expedition footage that look like science even when the substance (peer review, named authors, published data) is missing.
- Distrust of academic gatekeepers means that when anthropologists say 'these are deformed human skulls', some hear a cover-up rather than a conclusion, and read every unpublished DNA teaser as suppressed proof.
- There is a small kernel of real open science here, about the limits and social meaning of cranial deformation, which a motivated viewer can inflate into evidence that the mainstream account is incomplete.

## Open questions
- How much of the extreme variation across the roughly 300 skulls reflects different binding techniques, social rank or regional style, and whether any individual crania show pathology rather than deliberate shaping, is still being worked out by specialists.
- Whether usable, uncontaminated ancient DNA can ever be recovered from these particular remains, given decades of handling and burial in a harsh environment, remains genuinely uncertain, which is part of why unverified 'DNA results' keep circulating.
- The precise cultural purpose the Paracas attached to head shaping, whether it marked lineage, status or group identity, is reconstructed from context rather than settled, as with cranial deformation in other cultures.
- The full provenance and handling history of skulls in private collections, including the ones sampled for the disputed DNA claims, is not fully documented in the public record.
