Step-by-step explanation:
The subsistence pattern that happened around 6,000-7,000 B.P. today was a gathering-hunting mode of subsistence. During this time, our earliest ancestors lived as hunter-gatherers, relying on hunting animals for meat and gathering wild fruits, vegetables, and cereals for sustenance. They would settle in an area briefly when resources were abundant, but would move on once those resources ran low. This pattern of subsistence involved a nomadic lifestyle and did not typically involve trade between groups due to scarcity of goods.
