Hunter-gatherers
Many groups of 'nomadic' hunter-gatherers (also known as foragers) moved from campsite to campsite, following game and wild fruits and vegetables. Hunting and gathering was the ancestral subsistence mode of Homo, and all modern humans were hunter-gatherers until around 10,000 years ago.
Following the development of agriculture, hunter-gatherers were displaced by farming or pastoralist groups in most parts of the world. Only a few contemporary societies are classified as hunter-gatherers, and many supplement, sometimes extensively, their foraging activity with farming and/or keeping animals.
