Pleistocene-Era Hominins and Archaeology

Pleistocene-era hominin research draws on ancient DNA, fossil records, and stone tool assemblages to reconstruct the evolutionary history of humans and our closest relatives — Neanderthals and Denisovans — across roughly the last 2.6 million years. Sequencing the Neanderthal and Denisovan genomes has revealed that interbreeding between these groups and early modern humans was more widespread than fossil evidence alone suggested, reshaping longstanding debates about where and how *Homo sapiens* emerged. Archaeologists working on Paleolithic sites continue to probe when distinctly modern behaviors — symbolic thought, complex toolmaking, long-distance resource exchange — first appeared and whether such capacities were unique to our lineage. Open questions about what drove Pleistocene megafauna extinctions, and how much human activity versus climate change was responsible, remain actively contested and carry direct implications for understanding humanity's early ecological impact.
