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

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

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.

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

The paper compares event cognition in humans, great apes, and infants, finding that adults and apes track events as agent-patient relations, while infants do not.

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