Scientists from the Institute of Chemical Ecology. Max Planck in Germany discovered traces of ancient people in the Nefud Desert, Saudi Arabia. They recorded them on the route along which the group of homo sapiens left Africa and moved to Europe.

Paleontologists used the technology of optically stimulated luminescence, which made it possible to establish the height and weight of people in their tracks. The latter were recorded on the route along which the group of homo sapiens left Africa and crossed into the territory of modern Europe. Traces and a parking lot were found in the northern part of Saudi Arabia, and people were here for a short time. They got food in the lake and used the water for domestic needs. However, this reservoir was visited by buffaloes, camels and elephants. Presumably, the ancient people hunted large mammals, but they did not stay near this reservoir, but used it as a starting point before a longer journey.
Through reconstruction, scientists have traced the path of movement of homo sapiens and animals through the Nefud desert to Europe. The migration of people and fauna was caused by natural climatic changes, while Saudi Arabia resembled the semi-arid grasslands of the modern African savanna.
In total, about 700 prints were found, and they were identified as traces of homo sapiens. Groups of 3-6 people walked along the path. By the presence of anatomical features, travelers can be attributed more to modern humans than to Neanderthals.
