Abstract Increased population density is among the proposed drivers of the behavioural changes culminating in the Middle to Later Stone Age (MSA-LSA) transition and human dispersals from East Africa, but reliable archaeological measures of demographic change are lacking. We use Late Pleistocene-Holocene lithic and faunal data from Nasera rockshelter (Tanzania) to show progressive declines in residential mobility-a variable linked to population density-and technological shifts, the latter associated with environmental changes. These data suggest that the MSA-LSA transition is part of a long-term pattern of changes in residential mobility and technology that reflect human responses to increased population density, with dispersals potentially marking a complementary response to larger populations.This article is part of the themed issue 'Major transitions in human evolution'.
