Abstract

Smaldino proposes emergent properties of human groups, arising when individuals display both differentiation and organization, constitute a novel unit of cultural selection not addressed by current evolutionary theory. We propose existing theoretical frameworks for maintenance of genetic diversity - social heterosis and social genomes - can similarly explain the appearance and maintenance of human cultural diversity (i.e., group-level traits) and collaborative interdependence.

摘要

斯莫尔迪诺提出，当个体表现出差异化和组织化时，人类群体的突现属性就会出现，这构成了当前进化理论未涉及的文化选择的新单位。我们提出，现有的维持遗传多样性的理论框架——社会杂种优势和社会基因组——同样可以解释人类文化多样性（即群体层面的特征）和协作相互依存的出现和维持。
