Final answer:
People settled in that specific part of West Africa due to factors such as overpopulation, disease, and changes in climate. The Bantu people's skill in ironworking and their ability to clear land for agriculture also played a significant role in the settlement.
Step-by-step explanation:
The migration of people speaking Bantu languages to the specific part of West Africa was influenced by various factors. Some scholars believe that overpopulation, disease, or changes in the climate could have prompted the movement. Additionally, the Bantu people's knowledge of ironworking allowed them to make better tools and weapons, which facilitated clearing of land for agriculture. The original populations of these areas were primarily hunters and gatherers, but they were either assimilated into the Bantu population or forced to live in more remote regions.
