is the only species alive able to take advantage of its cognitive abilities to inhabit almost all environments on Earth. Humans are able to culturally construct, rather than biologically inherit, their occupied climatic niche to a degree unparalleled within the animal kingdom. Precisely, when hominins acquired such an ability remains unknown, and scholars disagree on the extent to which our ancestors shared this same ability. Here, we settle this issue using fine-grained paleoclimatic data, extensive archaeological data, and phylogenetic comparative methods. Our results indicate that whereas early hominins were forced to live under physiologically suitable climatic conditions, with the emergence of , the climatic niche expanded beyond its natural limits, despite progressive harshening in global climates. This indicates that technological innovations providing effective exploitation of cold and seasonal habitats predated the emergence of .
人类是现存唯一能够利用其认知能力栖息于地球上几乎所有环境的物种。人类能够通过文化建构而非生物遗传来占据其气候生态位，这在动物王国中是无与伦比的。确切地说，古人类何时获得这种能力尚不清楚，学者们对于我们的祖先在多大程度上具备同样的能力也存在分歧。在此，我们利用精细的古气候数据、广泛的考古数据和系统发育比较方法来解决这个问题。我们的结果表明，早期古人类被迫在生理上适宜的气候条件下生活，而随着[此处原文缺失关键信息]的出现，尽管全球气候逐渐变得恶劣，气候生态位却扩展到了其自然极限之外。这表明，在[此处原文缺失关键信息]出现之前，就已经有了能够有效开发寒冷和季节性栖息地的技术创新。
