Archaeological studies, artifacts are those produced from the manual work of the human being. These are usually the main characteristics that help to generate certain particularities of certain cultures, especially as extinct ones.
Through archaeological artifacts, current academic understanding places the proto-Bantu ancestral homeland in West Africa, near the current southwestern border of Nigeria and Cameroon c. 4,000 years ago (2000 BC), and regards the Bantu languages as a branch of the Niger-Congo language family.
Based on artifact comparisons it is believed that Proto-Bantu, the hypothetical ancestor of the Bantu languages, had strong ancestral affinities with a group of spoken languages in southeastern Nigeria. Some scholars propose that the Bantu languages spread east and south from there, to more dispersal secondary centers, over hundreds of years.
