在考古学、语言学和干细胞学等人类学领域中使用系统发育方法（涉及通常所谓的“文化数据”）是基于人类文化进化和生物进化之间的类比。我们需要彻底理解这种类比，包括人类学数据如何符合生物学中使用的系统发育树模型。我提供了人类学数据集与生物学的表型和基因型数据集的直接比较。人类学数据集近似地拟合树模型以及基因型数据，这比表型数据的拟合差得多。这对于具有<500个简约信息字符的数据集以及较大的数据集都是如此。这意味着跨文化（水平）过程在文物的进化中非常重要，分支历史（垂直）过程也是如此，因此系统发育网络将是比系统发育树更合适的模型。
The use of phylogenetic methods in anthropological fields such as archaeology, linguistics and stemmatology (involving what are often called “culture data”) is based on an analogy between human cultural evolution and biological evolution. We need to understand this analogy thoroughly, including how well anthropology data fit the model of a phylogenetic tree, as used in biology. I provide a direct comparison of anthropology datasets with both phenotype and genotype datasets from biology. The anthropology datasets fit the tree model approximately as well as do the genotype data, which is detectably worse than the fit of the phenotype data. This is true for datasets with <500 parsimony-informative characters, as well as for larger datasets. This implies that cross-cultural (horizontal) processes have been important in the evolution of cultural artifacts, as well as branching historical (vertical) processes, and thus a phylogenetic network will be a more appropriate model than a phylogenetic tree.
