Why do you think the ancestors of the Egyptians abandoned African cereals in favor of wheat and barley?

The ancestors of the Egyptians likely abandoned African cereals in favor of wheat and barley due to the latter's higher yields and adaptability to the Nile's irrigation system. Wheat and barley thrived in the fertile soil of the Nile Valley, providing a more reliable food source. Additionally, the cultivation of these grains aligned with the societal and economic shifts towards more complex agricultural practices and trade networks. This transition may have also been influenced by interactions with neighboring cultures that had already adopted these crops.
