Quizplus · Accepted Answer

The large-scale ecological changes in Africa, specifically the formation of expansive grasslands and savannas, created an environment that favored the emergence and evolution of larger-brained and more adaptable hominins, such as Homo erectus and eventually Homo sapiens.
