Paper short abstract:
Environmental change in the Eastern African Rift has long been assumed to play a key role in hominin evolution. We use distribution modelling of past climates to analyze the trajectory of habitability around Kilombe in the Baringo basin.
Paper long abstract:
Environmental change in the Eastern African Rift System (EARS) has long been assumed to play a key role in hominin evolution, speciation, extinction, and migration. Climatic conditions in Pleistocene Africa are known to have varied asynchronously across the landscape, affecting the distribution of suitable habitats and contributing to the fragmentation and coalescence of hominin populations. Our paper explores how climatically mediated habitat suitability in the EARS may have varied through time using distribution modelling based on new high-resolution climate simulations from the Global Model Climate Emulator. We analyze the trajectory of habitability at Kilombe, Moricho, and surrounding areas, with a focus on temperature and precipitation conditions during late Acheulean and MSA occupations.
