Integrating Past Environmental Changes within the Context of Human Evolution through Proxy and Modeling Frameworks
Session ID#: 251246
Session Description:
Reconstructing past environmental changes is critical for understanding the influence of climate on human evolution. However, discrepancies between proxy records and climate model output add large uncertainties to accurately assess past environmental changes and their impacts on hominin groups — a challenge exacerbated by disciplinary silos. We welcome studies that use (isotope-enabled) model simulations combined with a variety of climate archives (sediments, speleothems, corals), and a range of geochemical, botanical, and other proxies to better understand responses of past climate change on human evolution, migration, or settlement patterns.As models struggle to simulate proxy-evident changes, this session prioritizes benchmarking climate models with proxy data, human migration/evolution modeling, proxy-model assimilation approaches and assessments of their uncertainties. We aim to foster dialogue between (paleo)climate modelers, (bio)geochemical proxy scientists, and anthropologists/ecologists to co-develop an integrative narratives of shifting paleoenvironments and their role in shaping hominin groups. We encourage submissions from early-career researchers.
