Hunting was a crucial component of hunter-gatherer societies before the domestication of livestock and the dawn of agriculture, beginning about 11,000 years ago in some parts of the world. In addition to the spear, hunting weapons developed during the Upper Paleolithic include the atlatl (a spear-thrower; before 30,000 years ago) and the bow (18,000 years ago). By the Mesolithic, hunting strategies had diversified with the development of these more far-reaching weapons and the domestication of the dog about 15,000 years ago. Evidence puts the earliest known mammoth hunting in Asia with spears to approximately 16,200 years ago.
