in permanent dwellings.
A nomadic lifestyle can be associated to one in which a person does not settle at a particular place. These nomadic groups from ancient times are known as pastoralists who move from one place to another.
Hunter-gatherers used to obtain food by hunting and gathering the wild food sources in contrast to agricultural societies, which obtain food mainly by the domestication of plants and animals.
These groups would hunt and gather food in the place as much as possible and then they will move to another place and hence cannot have permanent dwellings.
