An inverse correlation between linguistic and genetic diversity

The paper shows that genetic diversity is inversely correlated with linguistic diversity, with isolation promoting linguistic diversification and contact promoting homogenization.

Global patterns of genetic admixture reveal effects of language contact

The paper uses genetic admixture to estimate language contact effects globally, finding shared features between admixed populations and language pairs in the same area.

A Phylogenetic Perspective on the Syntax-Semantics Interface: A Case Study in Clause Linkage Constructions

The paper models phylogenetic dynamics of clause linkage constructions across languages to assess semantic influence on syntax, finding moderate lineage-specific effects and minimal geographic impact.

Linguistic evolution minimizes the amount of syntactic hierarchy in grammar

The paper uses phylogenetic modeling to show that languages tend to minimize syntactic hierarchy in grammar, with cultural variation, likely due to learning costs.

Common marmosets use body posture as multi-functional signal to solicit, maintain, and modify social play

This study shows common marmosets use body posture signals to regulate social play by increasing play probability, duration, diversity, and likelihood of play fighting.
