学者们奋进了解人类进化与气候变化之间的关系。这对尼安德特人来说尤其重要，他们在欧亚极端的环境变化和冰川作用中幸存下来，在寒冷的间冰期阶段神秘地灭绝了。在这里，我们整合了来自法国东南部的两个尼安德特人和一个现代人的气候，牙齿生长和金属暴露的每周记录。尼安德特人比现代人居住在更凉爽和季节性更强的时期，在冬季表现出儿童发育压力。在一个例子中，这种压力可能包括骨骼动员元素储存和体重减轻;这个人出生在春天，似乎在2.5年后断奶。两个尼安德特人在深冬和/或早春至少两次接触过铅。这种多学科的方法阐明了古代环境和古人类古生物学之间的直接关系。
Scholars endeavor to understand the relationship between human evolution and climate change. This is particularly germane for Neanderthals, who survived extreme Eurasian environmental variation and glaciations, mysteriously going extinct during a cool interglacial stage. Here, we integrate weekly records of climate, tooth growth, and metal exposure in two Neanderthals and one modern human from southeastern France. The Neanderthals inhabited cooler and more seasonal periods than the modern human, evincing childhood developmental stress during wintertime. In one instance, this stress may have included skeletal mobilization of elemental stores and weight loss; this individual was born in the spring and appears to have weaned 2.5 years later. Both Neanderthals were exposed to lead at least twice during the deep winter and/or early spring. This multidisciplinary approach elucidates direct relationships between ancient environments and hominin paleobiology.
