Final answer:
Gatherer-hunter societies are egalitarian and practice sharing and consensus decision-making. Material possessions and food are shared based on need. Violence and conflict are rare in these societies.
Step-by-step explanation:
Gatherer-hunter societies, such as bands or foragers, are considered egalitarian due to their social structures and practices. They do not typically have a formal leadership position and decisions are made through discussion and consensus. Material possessions are shared based on need and all gathered and hunted foods are shared equally among band members. Stinginess and excessive pride are discouraged and can lead to social punishment. In addition, violence and conflict are rare among gatherer-hunters.
