They arranged plant materials, used fire to maintain their sleeping areas, and repeatedly cleared old bedding before creating new layers. The discovery offers a rare glimpse into everyday habits from a time when human culture was still taking shape.A South African cave preserves the earliest signs of organised sleeping areas The evidence comes from Border Cave, a rock shelter in South Africa’s KwaZulu-Natal region that has become one of the most significant archaeological sites for understanding early Homo sapiens behaviour.The cave was occupied repeatedly between roughly 220,000 and 43,000 years ago, leaving behind traces of tools, food remains, and signs of how people organised their living spaces.
