What Do Lithics Tell Us About Cultural Evolution? Insights From the Central African Record

Archaeometry, EarlyView.
ABSTRACT While Western historical narratives often incorporate a biased vision of human evolution—driven by a progressive view tied to a progressively evolving state of culture—this paper proposes combining archaeological lithic data with epistemological reflections to critique the modern regime of historicity, where progress is assumed as rational ...

Response of Remote Tropical West Pacific Islands to Climate Variability: A Multiproxy Record From T‐Lake, Palau, Spanning the Early Holocene to Present

Archaeometry, EarlyView.
ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.

Untangling nutrient co‐regulation of ombrotrophic peatland development

Boreas, EarlyView.
Multi‐method (FTIR, FT‐NIR and TGA) approaches characterizing the organic peat constituents at Holcroft Moss reveal a record of switches that reflect broadly hydroclimate variability governing the decomposition patterns. There are periods, however, where hydroclimate does not fully explain the variability observed and instead changes appear linked to ...
