Step-by-step explanation:
A larger, flatter stone used to grind seed into flour is called a metate. This ancient grinding tool was accompanied by a hand-held stone known as a mano, used in conjunction to grind grains and other food items. Archaeologists like Jennie Ebeling and Yorke Rowan have studied these tools extensively, uncovering their significance in ancient food production. The metate and mano were vital in transforming dried corn and other foods into flour, essential for making traditional food items such as tortillas in Mexican culture. These grinding stones were not only utilitarian, but they also held cultural significance, often being passed down through generations and acting as symbols associated with the women who used them.
