We report here on direct evidence for the intensive consumption of marine foods by anatomically modern humans at approximately 12,000 years ago. We undertook isotopic analysis of bone collagen from three humans, dating to the late Palaeolithic, from the site of Kendrick's Cave in North Wales, UK. The isotopic measurements of their bone collagen indicated that ca. 30% of their dietary protein was from marine sources, which we interpret as likely being high trophic level marine organisms such as marine mammals. This indicates that towards the end of the Pleistocene modern humans were pursuing a hunting strategy that incorporated both marine and terrestrial mammals. This is the first occurrence of the intensive use of marine resources, specifically marine mammals, that becomes even more pronounced in the subsequent Mesolithic period.
我们在此报告直接证据，表明约12000年前解剖学意义上的现代人大量食用海洋食物。我们对来自英国北威尔士肯德里克洞穴遗址的三名旧石器时代晚期人类的骨胶原进行了同位素分析。对他们骨胶原的同位素测量表明，其膳食蛋白质约30%来自海洋来源，我们认为这可能是高营养级的海洋生物，如海洋哺乳动物。这表明在更新世末期，现代人采用了一种同时包含海洋和陆地哺乳动物的狩猎策略。这是首次出现对海洋资源，特别是海洋哺乳动物的大量利用，这种现象在随后的中石器时代变得更加明显。
