Climate change
Step-by-step explanation:
According to various scientific research derived from several fields most notably, paleoanthropology revealed that Apes went extinct in southern Europe (including France, Spain, Italy, and Greece) during the late Miocene, probably as a result of "CLIMATE CHANGE"
It is believed that around 22 to 6 million years ago, a huge number of Apes lived across southern Europe, an assertion which is confirmed by fossil records. These fossils preceded the fossils records of modern humans found in Africa.
Hence, it is belied what could have led these Apes to migrate to Africa is due to Climate change.
