A study finds that access to stone and water influenced where early humans lived in desert environments.

What it means

This New Scientist article reports on a new Nature study that uses computational models to understand early human settlement in deserts. The research finds that access to stone for tool-making and fresh water were the primary constraints governing where early humans could live, challenging the primacy of climate-only models. The study provides a more nuanced understanding of human dispersal in arid environments.
