Answer:
Modern hunter-gatherers live in a few isolated areas of the world where developing a civilization is hard: either because of climatic conditions, because of the geography or both. Among these regions we have: The Amazon Rainforest, where there are hundreds of small hunter-gatherer groups, some of them still uncontacted, some areas of Central Africa like the rainforests of Congo, and the Kalahari Desert, and some areas in Siberia. The Island of Papua New Guinea also hosts a few hunter-gatherer groups.
These groups share many similarities with early hunter-gatherers: they form small bands because the amount of food they collect or hunt does not support very high populations, there social structures are not as hierarchical, with income and wealth inequality being almost non-existent, and they engage in trade with other groups for those goods that they cannot produce or collect on their own. The biggest difference is that many of these hunter-gatherers keep contact with other civilizations. For example, a few groups of the Amazon Rainforest trade with Brazilian or Peruvian farmers.
