Marine resource abundance drove pre-agricultural population increase in Stone Age Scandinavia.

ABSTRACT: How climate and ecology affect key cultural transformations remains debated in the context of long-term socio-cultural development because of spatially and temporally disjunct climate and archaeological records. The introduction of agriculture triggered a major population increase across Europe. However, in Southern Scandinavia it was preceded by ~500 years of sustained population growth. Here we show that this growth was driven by long-term enhanced marine production conditioned by the Holocene Thermal Maximum, a time of elevated temperature, sea level and salinity across coastal waters. We identify two periods of increased marine production across trophic levels (P1 7600-7100 and P2 6400-5900 cal. yr BP) that coincide with markedly increased mollusc collection and accumulation of shell m
