Analysis casts doubt on ancient drying of northern Africa's climate, raising new questions about early human evolution
A study led by researchers from Brown University finds that rainfall patterns across northern Africa remained largely stable between 3.5 and 2.5 million years ago—a pivotal period in Earth's climate history when the Northern Hemisphere cooled and places like Greenland became permanently glaciated.
