A research paper published a few days ago, on August 3, 2026, has looked into the the microstructure of the skull of Homo antecessor,a hominin that lived in what is now Spain, 800,000 to 900,000 years ago.
The article, Parietal thickness and Homo antecessor: A description of three new fragments from Gran Dolina, Atapuerca, Spain🔒, by Gallareto-Sande, Bruner, Saladié, and Martinó,n-Torres focuses on the similarities of the bone structure of H. antecessor and Neanderthals, and H. sapiens.
The authors note that although it had initially been "proposed as the last common ancestor of Neanderthals and modern humans based on a combination of derived facial features and primitive postcranial and dental traits" later studies suggested it was a branch or "stem" within our clade.
According to Phys.org the paper found that the the "total cranial vault thickness of these adult individuals falls within the range observed in modern humans and Neanderthals and is clearly lower than that found in Homo erectus and other early Pleistocene hominins."
The sample used bones from four adult individuals which were analyzed using computer microtomography. This allowed the researchers to study each layer of the bone structure. Though they caution that the sample is small, the layer knwon as diplo%ë on the inner side of the bone is very similar, in its thickness to that of humans and Neanderthals. Howver, the outer and inner layers show differences between antecessor and Neanderthals and humans, they are slightly thinner and thicker, respectively, than theirs. Even so, they are very unlike those of the other hominins like Homo erectus and the African species.
The paper does not say so, but it makes me wonder if this European hominin evolved there, in situ, from older erectus populations, and is, in fact, the Last Common Ancestors of Modern Humans and the Neanderthal-Denisovan lineages. See my post about this possibility, and also this post, and this post.
