Early humans settled where water and tool stone met

A research team surveyed about 1,500 km of the Rub' al Khali, the world's largest sand sea, and modelled the Arabian Peninsula. They suggest early human settlement followed places with both water and stone suitable for tools.
The study is peer-reviewed and appears in the journal Nature. The team found almost no stone tools around ancient lakes, which led to the idea that water alone did not decide where people lived. This may matter for how researchers read dispersal routes, including those out of Africa. The survey was a single 35-day transect in 2023, so the conclusion rests on missing evidence plus modelling.
