A parasite‐driven wedge: infectious diseases may explain language and other biodiversity

Human parasitic disease richness will be positively associated with global linguistic diversity (1289).

Partial correlation was conducted to account for potentially confounding effects of latitude, national GDP, population size, and land area.
