Answer:
Evidence of iron production found in West Africa, which dated back to dating to about 500 B.C.
Explanation:
Iron production helped the early farmers to cultivate by moving from copper or bronze tools to Iron. Iron tools helped people toil in tough lands and clear forests to use more land for farming. Iron tools such as sickles and plough were much stronger than the copper and bronze, which helped them in growing different crops like corn, barley, and millet, but the wheat crop was most predominant among the farmers.
