Final answer:
The proto-Bantu people lived in the area between modern-day Nigeria and Cameroon. They were farmers who cultivated crops and extracted oil from trees in the region's rainforests. Over time, they moved southward through a grassland corridor.
Step-by-step explanation:
The home of the proto-Bantu people was in the area between modern-day Nigeria and Cameroon in West and Central Africa. They were farmers who cultivated pearl millet and yams and extracted oil from palm and bush candle trees in the region's rainforests. Gradual changes in weather patterns allowed the Bantu to move southward through a grassland corridor, which was once covered in dense rainforest.
