Answer:
To help them cut the grain, the neolithic farmers invented the sickle.
Step-by-step explanation:
The beginnings of agriculture are dark, but it has been shown that the paleolithic hunting and gathering tribes collected wild cereal seeds that nature provided spontaneously. The main innovation of the neolithic was the discovery of own forms of food production from agriculture and livestock. This change did not occur as quickly throughout the middle east but was caused by a series of slow transformations. It was a domestication process performed by artificial selection. These transformations coexisted with the life forms typical of the paleolithic.
The existence of wild crops of wheat and barley in the fertile triangle between the Aegean, Caspian and Red seas was a providential gift for a hungry humanity. The drawback was that when the plant matured, the ears exploded and dispersed the grains. The human being had to realize that it was necessary to reap the spikes before that time came and wait for the grain to ripen afterwards. For this specific work the sickle was invented: formed by a piece of wood or curved bone inlaid with small sharp stones on its inner edge.
