Archaeologists have traditionally conceptualized culture areas and associated ethnic group boundaries as reflecting significant degrees of dissimilarity between “core” and “peripheral” cultural types. This dissimilarity is typically thought to correlate with gradual geographic isolation. However, an alternative model has been presented that underscores the importance of inter-group interaction to ethnic group formation through a process known as “schismogenesis”, or progressive differentiation. According to this model, societies define themselves through an absence of borrowing rather than through an absence of interaction. Here, we make a case for schismogenesis between Late Developmental Northern Rio Grande and Chacoan communities.

新墨西哥州北部发育晚期的 Northern Rio Grande 和 Chacoan 社区之间的分裂案例


考古学家传统上将文化区域和相关种族群体边界概念化，以反映“核心”和“边缘”文化类型之间的显著差异。这种差异通常被认为与逐渐的地理隔离有关。然而，已经提出了另一种模型，它强调了群体间互动对通过称为“分裂发生”或渐进分化的过程形成种族群体的重要性。根据这个模型，社会通过没有借贷而不是没有互动来定义自己。在这里，我们提出了晚期发育的 Northern Rio Grande 和 Chacoan 社区之间的分裂发生案例。
