尽管调查历史悠久，但围绕尼安德特人是否因气候变化或与解剖学现代人类（AMH）的竞争而灭绝仍存在相当多的争论。我们应用一种将考古学和年代学数据与高分辨率古气候模拟相结合的新方法来定义在海洋同位素阶段3的寒冷和温和阶段交替期间与尼安德特人和AMH适应系统相关的生态文化位。我们的结果表明尼安德特人和AMH利用了类似的生态位，并且可能在没有接触的情况下继续这样做。格陵兰 Interstadial 8 期间，欧洲西南部尼安德特人的分布范围向南收缩并不是由于气候变化或适应变化，而是同时发生的 AMH 地理扩张似乎产生了导致尼安德特人灭绝的竞争。
Despite a long history of investigation, considerable debate revolves around whether Neanderthals became extinct because of climate change or competition with anatomically modern humans (AMH). We apply a new methodology integrating archaeological and chronological data with high-resolution paleoclimatic simulations to define eco-cultural niches associated with Neanderthal and AMH adaptive systems during alternating cold and mild phases of Marine Isotope Stage 3. Our results indicate that Neanderthals and AMH exploited similar niches, and may have continued to do so in the absence of contact. The southerly contraction of Neanderthal range in southwestern Europe during Greenland Interstadial 8 was not due to climate change or a change in adaptation, but rather concurrent AMH geographic expansion appears to have produced competition that led to Neanderthal extinction.
