Smaldino proposes a conceptual extension to the theory of cultural evolution to include emergent group-level traits as a unit of selection. It is important to recognize the role that group-level traits have played in the evolution of human culture. However, the emergent group-level trait of division of labor provides an illustrative example that is implementable within the existing framework of cMLS theory and may not even need a departure from the standard model.
斯莫尔迪诺提出了一个概念性的延伸，将文化进化理论扩展到包括新兴的群体水平特征作为选择的单位。认识到群体水平特征在人类文化进化中的作用是很重要的。然而，劳动分工的新兴群体水平特征提供了一个可实现的例证，它可以在现有的 cMLS 理论框架内实施，甚至不需要偏离标准模型。
