In 2017, the discovery of ancient human fossils at the Jebel Irhoud site in Morocco reshaped our understanding of human history. These fossils, dated to about 300,000 years ago, revealed that our direct ancestors lived much earlier and in a different part of Africa than previously believed. Now, Brazilian designer Cicero Moraes is using his expertise in facial reconstruction to give a face to one of these early Homo sapiens individuals. His work combines forensic science with modern technology to create a visual representation of what this ancient human might have looked like.
Moraes' method involves using a facial tomography of a modern human and adjusting the skull to match that of a Jebel Irhoud fossil. This process, known as anatomical deformation, aims to align the donor's skull structure with the target skull and extend these changes to the soft tissues, creating a realistic facial approximation. According to a study published in the journal Heritage, this technique helps generate a face that reflects how the individual might have appeared when alive.
The virtual skull alone cannot indicate the amount of soft tissue covering it. To ensure accuracy, the model was compared to numerical data from the original fossils. The endocranial volume calculated from the 3D design, approximately 1364 milliliters, closely matches the volume from the original fossil (1375 milliliters). In comparison, the average endocranial volume of a modern human is around 1328 milliliters. This alignment supports the accuracy of the reconstruction.
The skull of the reconstructed Homo sapiens is a combination of several fossils. The main part of the skull comes from specimen Irhoud 1, first discovered in 1961. The mandible with teeth is from Irhoud 10, and other fragments are from Irhoud 21 and 22, all found in the same geological layer. This combination ensures a comprehensive representation of the individual's anatomy.
The final step in the reconstruction involves adding color, hair, and facial hair to create what the researchers call "the artistic version." This version is intended for the general public and includes elements that are not directly supported by the fossil evidence. Instead, these features are based on artistic conventions and anthropological studies, aiming to suggest plausible traits for an individual from North Africa who lived around 315,000 years ago. This reconstructed face provides a glimpse into the appearance of one of the earliest known Homo sapiens, who lived during the Middle Paleolithic era when the Sahara was a lush, green region.
