Facial Reconstruction of 3,000-Year-Old Ecuadorian Ancestor Shared with Descendants

An international team of researchers has unveiled a digital facial reconstruction of a man who lived in the central Andes of Ecuador over 3,000 years ago. The project has provided closure to one of anthropology’s more contentious historical debates, confirming the individual’s Native American lineage.

The reconstruction is based on the Punin-2 skull, which was unearthed by a farmer in a ravine near the town of Punín in the Chimborazo region during the 1970s. This discovery followed the finding of a similar skull, Punin-1, in the same location in 1923 by an expedition from the American Museum of Natural History.

Upon its initial discovery, the Punin-1 skull drew significant scientific attention due to its archaic features, particularly a prominent brow ridge. In 1925, some scientists hypothesized that these traits indicated Oceanic ancestry, potentially stemming from ancient contact with populations from Australia or the Pacific Islands. Further speculation arose because the sediment layer containing the skull predated the arrival of modern humans, leading some to wonder if the remains belonged to an extinct relative such as Homo erectus or Neanderthals.

However, subsequent studies have debunked these earlier theories. The new reconstruction indicates that the Punin-2 skull belongs to a modern human with purely Native American ancestry. Christopher Rynn, a forensic craniofacial anthropologist at the University of Dundee, stated there is no doubt the individual descended from ancestral groups of North Siberians and East Asians during the last ice age.

“Punín-2 resembles an East Asian skull from the front, but not at all from the side,” Rynn told Live Science. “It explains a lot to me about the broader nature of skull and face shape differences between Native Americans and East Asians.”

Rynn collaborated with colleagues in Ecuador, including sculptor Hector Flores Franco from the University of Chimborazo, to develop the image. To ensure accuracy, Rynn intentionally limited his prior knowledge of the skull’s origin, relying solely on its shape for the reconstruction. He did, however, incorporate local guidance regarding hairstyle, which is distinctive to specific tribal groups in the Chimborazo region. The digital model features black hair parted in the middle. A physical bust using real hair is scheduled for completion in 2027.

Local advice also influenced the placement of the eyes. Early drafts rendered the eyes too protrusive, mimicking typical East Asian features, so Rynn adjusted them to be deeper set, aligning with Indigenous American characteristics.

Controversy also surrounded the dating of the remains. When Punin-2 was found, researchers suggested it was contemporaneous with Pleistocene fossils of extinct animals like mastodons and giant sloths found in the same ravine. Geological analysis has since disproven this, demonstrating that erosion and soil movement had mixed the younger human remains with older ice-age fossils. Current evidence places the hunter-gatherer individual in the Chimborazo region between 3,000 and 4,000 years ago, at approximately 50 years of age at death.

The research team is currently raising funds for further investigations, which will include a reconstruction of the Punin-1 skull and ancient DNA analysis of both specimens. “DNA will tell us the true genetic lineage,” Rynn noted.

The digital reconstruction has been presented to a select group of people from the Chimborazo region who are likely descendants of the man. “It’s a portrait of their actual ancestor,” Rynn said. “They seem to like it!”
