These remains exhibit unique characteristics, distinguishing them from other European fossils, leading to their classification as a new Homo ancestor species. Other findings in Atapuerca’s Sima de los Huesos (1974), approximately 300,000 years old, belong to pre-Neanderthal populations related to Homo heidelbergensis, likely of African
