Nasal Gracilization in Sri Lankan Indigenous Vedda: Phenotypic Plasticity and Evolutionary Continuity.

Abstract excerpt

OBJECTIVES: The nasal complex, a climatically sensitive trait, offers insight into both long-term adaptation and short-term phenotypic plasticity. We test whether nasal morphology exhibits plasticity parallel to postcranial gracilization in response to subsistence shifts, using Sri Lanka's Indigenous Vedda as a model population. They represent a unique lineage with deep evolutionary continuity to the island's...
