国内外大量的考古资料证明,在距今5.3万~2.5万年间,人类的文化发生了显著的进步,石器形态更加规范,骨角器和装饰品大量出现,狩猎工具更加专业化,遗址功能分区日趋明显,出现有意识的埋葬行为等。这些新内容的出现标志着旧石器中期文化的结束和晚期文化的开始~([1~9])。而古气候学的研究表明,这一时期恰好是寒冷干燥的末次冰期内一个气候相对比较温暖湿润的小间冰阶,亦即深海氧同位素3阶段(MIS_3)~([2])。文化演进与气候变化的耦合似乎暗示着两者之间存在着某种内在的联系。
A large number of archaeological data at home and abroad prove that during the period of 53,000 to 25,000 years ago, the human culture has undergone remarkable progress, the stone shape has become more standardized, the large number of angles and ornaments have emerged, hunting tools have become more specialized, Increasingly obvious, the emergence of conscious burial behavior. The emergence of these new contents marks the end of the Middle Paleolithic culture and the beginning of the late culture ~ (1 ~ 9). Paleoclimate studies show that this period happens to be a warm and humid inter-small ice stage in the cold-dry last glacial period, namely, the third stage of deep-sea oxygen isotopes (MIS 3) ~ (2). The coupling between cultural evolution and climate change seems to imply that there is some intrinsic link between the two.
