When the sea saved humanity

The article discusses the survival of human ancestors after facing possible extinction due to adverse climate conditions. The article describes the Earth's glacial stage known as Marine Isotope Stage 6 (MIS6) that rendered vast areas of land uninhabitable and left a human population that numbered only in the hundreds. The southern coast of Africa is said to have provided a haven for mankind's survival, owing to the ambient temperature of the region and year-round access to shellfish and edible plants. Archaeological research in the area has yielded items thought to be from humans that survived MIS6.
