Final answer:
The cultivation and repeated harvesting of wild grasses led to the domestication of grains like wheat, corn, and rice, which is known as agriculture revolution.
Step-by-step explanation:
The cultivation and repeated harvesting and sowing of the grains of wild grasses led to the creation of domestic strains of grains like wheat, corn, and rice. This process of domestication is known as agriculture revolution, which was a crucial development in human history. Through careful selection and planting of seeds from plants with desirable traits, humans gradually modified wild plants into crops that were larger, tastier, more nutritious, and easier to grow. This transformation allowed for the establishment of permanent settlements, the rise of specialized crafts, and the emergence of trade.
