Researchers have reconstructed the face of the oldest known Homo sapiens, offering a detailed look at what an early member of our species looked like around 315,000 years ago. Published September 13, 2026, in the journal Heritage, the digital facial approximation bridges scientific precision with public outreach by using open-source tools and a composite skull built from fossil remains unearthed in Morocco.
Origins of the Jebel Irhoud Fossils
Miners at the Jebel Irhoud site in Morocco uncovered the first skull, known as Irhoud 1, in 1961. Researchers initially described the specimen as a roughly 40,000-year-old African Neanderthal variant. Classification shifted dramatically in 2017 when a landmark study published in the journal Nature placed the remains at about 315,000 years old. That dating pushed the known fossil record of modern humans back by roughly 100,000 years and strengthened the theory that modern humans emerged through evolutionary changes across Africa.
Constructing a Composite Skull
Because no single skull from the site survived intact, researchers performed the reconstruction like a forensic jigsaw puzzle. Most of the braincase and upper face came from Irhoud 1, while the lower jaw was supplied by Irhoud 11. Portions of the upper jaw and teeth from specimens Irhoud 10, Irhoud 21, and Irhoud 22 completed the structure. Using images and video released by the Max Planck Institute for Evolutionary Anthropology in 2017, an international team rebuilt the composite skull via photogrammetry. Corresponding author Dr. Johari Yap Abdullah, a researcher at the Universiti Sains Malaysia and Saveetha University, and his colleagues utilized the Max Planck Institute data to anchor the volumetric orientation.
Digital Facial Approximation Methods
A team led by Brazilian researcher Cicero Moraes built the facial approximation using free, open-source software including Blender. The scientists applied a technique called constrained anatomical deformation, which starts with a computed tomography scan of an anonymized modern adult donor and digitally deforms its anatomy until the cranium matches the fossil geometry. Modern soft-tissue measurements from people of African ancestry guided the flesh thickness on the face. As the study authors write in Heritage,
Because no direct soft-tissue data exist for Middle Pleistocene hominins, the use of reference datasets derived from modern human populations represents a necessary methodological proxy rather than an assumption of biological equivalence.

Dual Renderings and Brain Volume Estimates
The researchers produced two distinct versions of the finished face for scientific comparison and public display. One version is a neutral grayscale rendering without hair to show underlying bone structure, while the second adds skin pigmentation, hair, and a beard. The digital model also yielded an endocranial volume of 1,364 milliliters, closely matching a previous 2018 CT-based estimate of 1,375 milliliters. After applying a correction from cranial capacity to estimated brain tissue, the team calculated a brain volume of about 1,230 cubic centimeters, which falls within the range seen in modern adult humans. The resulting portrait reveals a recognizably modern face, jaw, and teeth sitting behind a braincase that remains long and archaic. According to the study authors, the work demonstrates the feasibility of forensic facial approximation for complex Middle Pleistocene specimens while maintaining anatomical rigor.
