| | | | | A comprehensive re-analysis of a skull fragment found in a Greek cave back in the late 1970s suggests early modern humans were present in Eurasia some 210,000 years ago. Its the earliest indication of our species on the continent, but the lack of supporting archaeological evidence raises some questions. | |

| | | | | [AI summary] The article discusses the complexities of classifying human ancestors and the evolution of hominin phylogeny. It highlights the role of genetic data, such as mitochondrial DNA and the Neanderthal genome, in challenging traditional taxonomic classifications. The text also examines the significance of sexual dimorphism, cranial morphology, and molecular evolutionary processes in understanding human origins. Key points include the debate over species boundaries, the impact of DNA divergence among hominoids, and the use of geometric morphometrics in analyzing craniofacial variation. The article emphasizes the dynamic nature of taxonomy and the importance of integrating multiple lines of evidence to accurately reconstruct hominin evolutionary history... | |
