Climatic change and diet of the pre-Hispanic population of Gran Canaria (Canary Archipelago, Spain) during the Medieval Warm Period and Little Ice Age

The hard and soft tissue remains of a pre-Hispanic population the Gran Canaria Island at six different archaeological localities were studied using 14C dating stable isotope compositions. Radiocarbon indicates island occupation ranging from beginning 7th to mid-14th century. We analyzed oxygen compositions apatite phosphate bones some individuals. meteoric water (δ18Ow) show significant decrease −2.1 ± 1.5 −4.4 1.2‰ (VSMOW) Medieval Warm Period (MWP) Little Ice Age (LIA). This is interpreted reflect in air temperature by about 5 3 °C. Archaeological data along with δ13C, δ15N δ34S values indicate that relied on agriculture throughout However, contribution seafood diet observed sites located close shore. These results suggest cultural resilience Canaria, reflected relative constancy their light climate change.
