The hard and soft tissue remains of a pre-Hispanic population of the Gran Canaria Island at six different archaeological localities were studied using ¹⁴C dating and stable isotope compositions. Radiocarbon dating indicates island occupation ranging from the beginning of the 7th to the mid-14th century. We analyzed the oxygen isotope compositions of apatite phosphate bones of some pre-Hispanic individuals. The oxygen isotope compositions of meteoric water (δ¹⁸O_w) show a significant decrease from −2.1 ± 1.5 to −4.4 ± 1.2‰ (VSMOW) from the Medieval Warm Period (MWP) to the Little Ice Age (LIA). This is interpreted to reflect a decrease in air temperature by about 5 ± 3 °C. Archaeological data along with δ¹³C, δ¹⁵N and δ³⁴S values of soft tissue indicate that the pre-Hispanic population from Gran Canaria relied on agriculture throughout the 7th to mid-14th century. However, a significant contribution of seafood to the diet of the pre-Hispanic population is observed at archaeological sites located close to the shore. These results suggest cultural resilience in the pre-Hispanic population of Gran Canaria, reflected in the relative constancy of their diet in light of climate change.

使用¹⁴ C年代测定法和稳定的同位素组成研究了大加那利岛上西班牙裔前人口在六个不同考古地区的硬组织和软组织。放射性碳年代测定法表明了从7世纪初到14世纪中叶的岛屿占领。我们分析了西班牙裔前一些个体的磷灰石磷酸盐骨的氧同位素组成。大气水氧同位素组成（δ ¹⁸ ö_瓦特）示出了从-2.1±1.5 -4.4到±1.2‰（VSMOW）从中世纪暖期（MWP）到小冰期（LIA）一个显著降低。这被解释为反映出空气温度降低了约5±3°C。用δ沿考古数据¹³ C，δ ¹⁵N和δ ^34个软组织的价值观表明，从大加那利前西班牙人口依赖于农业在整个7日至世纪中叶，第14位。然而，在靠近海岸的考古现场发现海鲜对西班牙裔前人口的饮食有重要贡献。这些结果表明，大加那利岛前西班牙裔人口的文化适应力，反映在气候变化影响下他们饮食的相对稳定性。
