东亚与北美细石叶遗存的古环境

对东亚和北美更新世晚期和全新世早期古环境的分析可以了解，细石叶遗存是一类分布于差异极大的生态环境中的器物。它们于东亚和北美的广布应与史前人类开拓动物资源为主和流动性很大的生存方式有关。它们之间的相似性很可能是由于传播和迁移而非多次的独立发明。

THE PALEOENVIRONMENT OF MICROBLADE REMAINS IN EAST ASIA AND NORTH AMERICA

On the basis of the studies of paleoenvironment during the Late Pleistocene and the Early Holocene in East Asia and North America, it is suggested that microblade remains might have represented a lithic technology which occurred in extremely diversified environments. Their wide distribution in East Asia and North |America might have closely related with a highly mobile subsistence pattern which depended mainly on land mammalian resources. It is highly possible that the similarities between microblade remains in these regions could have been caused by diffusion and migration rather than independent inventions or cultural analogy.
