New research from Aarhus University provides insights on the migration of Homo erectus out of Africa about 2.1 million years ago.

Homo erectus utilized a 'green corridor' during a wetter and more vegetated period in northeastern Africa.

The Sahara, now a desert, transformed into a savannah-like environment due to recurring 'African Humid Periods'.

Researchers analyzed sediment cores from the Mediterranean Sea to determine the climate conditions during Homo erectus' migration.

Findings indicate that the Sahara was greener during this migration period than any other point in the last 4.5 million years.

The study suggests that Homo erectus likely migrated through a green corridor rather than crossing a desert.

This research provides significant insights into early human migration patterns.
