Critical Evaluation
The lecture is a masterclass in paleoanthropology, delivered by one of the field’s leading experts. Hublin’s presentation is meticulously structured, beginning with a historical overview of Neanderthal discoveries, then moving to their geographic range and anatomical distinctiveness. He uses clear visuals, including maps and 3D morphometric analyses, to illustrate his points. The scientific rigor is high: he distinguishes between well-established facts and more speculative interpretations, such as the role of Caspian Sea level changes in Neanderthal dispersal. He also acknowledges ongoing debates, such as the taxonomic status of Neanderthals. The sources cited are primarily his own research and that of his colleagues, which is appropriate for a lecture at this level. The content is dense but accessible, with technical terms explained. The title accurately reflects the content, as it is the second part of a series on the replacement of Neanderthals by modern humans. Overall, this is an excellent educational resource, providing deep insights into the current state of knowledge about archaic Eurasians.
