How did the the ability to work with iron affect food production and the types of jobs that villagers performed in West Africa?

The ability to work with iron significantly enhanced food production in West Africa by enabling the creation of more efficient farming tools, such as plows and hoes, which improved agricultural yields. This advancement allowed villagers to cultivate larger areas and support more complex societies. As a result, fewer individuals were needed for subsistence farming, leading to a diversification of jobs, including specialization in trade, craftsmanship, and other non-agricultural roles, fostering economic growth and social stratification in the region.
