Grammatical complexity is predicted by language phylogeny and spatial contiguity.


"The phylogenetic signal of fusion (λ = 0.97, <0.001) is stronger than that of informativity (λ = 0.85, <0.001). In other words, fusion and informativity scores are explained by the inheritance from a common ancestor and spatial diffusion among close neighbors."
