  abstract = {{A}lthough climate change is considered to have been a large-scale driver of {A}frican human evolution, landscape-scale shifts in ecological resources that may have shaped novel hominin adaptations are rarely investigated. {W}e use well-dated, high-resolution, drill-core datasets to understand ecological dynamics associated with a major adaptive transition in the archeological record similar to 24 km from the coring site. {O}utcrops preserve evidence of the replacement of {A}cheulean by {M}iddle {S}tone {A}ge ({MSA}) technological, cognitive, and social innovations between 500 and 300 thousand years (ka) ago, contemporaneous with large-scale taxonomic and adaptive turnover in mammal herbivores. {B}eginning similar to 400 ka ago, tectonic, hydrological, and ecological changes combined to disrupt a relatively stable resource base, prompting fluctuations of increasing magnitude in freshwater availability, grassland communities, and woody plant cover. {I}nteraction of these factors offers a resource-oriented hypothesis for the evolutionary success of {MSA} adaptations, which likely contributed to the ecological flexibility typical of {H}omo sapiens foragers.},
