Fig. 1: Phylogenetic distribution of data for state, intensive agriculture and grain.
From: State formation across cultures and the role of grain, intensive agriculture, taxation and writing
A maximum clade credibility tree of the global treeset22 with larger language families identified, matched to the data for state, intensive agriculture and grain from the EA. The maximum clade credibility tree is just one tree from the posterior distribution of 1,000 trees. All the analyses we report were performed on the full posterior distribution of trees, integrating over the considerable uncertainty in ancestral relationships between the world’s languages. The figure was produced using Treeviewer44.
