The social development of mankind mainly determines the level of "productive forces ". The impact of such a development on society is enormous. In ancient times, people were extremely unproductive and said they depended on hunting and fishing for a living. Because of the invention of farm tools and ploughs, the primitive society began to transition into a "agricultural society ", which made people's living standards change dramatically. In the agricultural society, the productive forces are still developing, and finally the "steam" has been invented, which indicates the human step into the "industrial society ". Then narita to saga the advent of the information age, that is, today's "science and technology society." This is human society The history of change took thousands of years of human accumulation to this point. However, not all human beings follow such a way of life, and in some places, because of their lack of productivity, they are still in agricultural society, and therefore their economies are relatively poor. But to say the worst, it is still the African tribe, because the African tribe has not yet entered the agricultural society, still in the most primitive way to survive, do you know which tribe? The last hunting tribe in the world. This tribe is actually Africa's "Haza tribe ", a known as the world's last hunting tribe. The tribe lives mainly in shrubbery around the west lake in tanzania, and in sparse shrubbery there are stone caves or simple thatched cottages built for them to rest. They don't have a permanent place to live, because they follow changes in flights from tokyo to saga water, seasons, fruit and prey, where crops are never grown, and where all sources of food depend on hunting. The Hazare tribe was discovered very late, because the Africans were not particularly familiar with them because they were hiding in the wilderness and rarely communicating with the outside world. So once discovered, the tribe was especially noticed by some international units. The survey showed that their total population was less than a thousand, and that groups of 20 to 30 would be formed, then scattered around the Engroengoro reserve, without growing food or raising livestock, or relying on the experience of a generation to survive, perhaps for more than 10,000 years No change has been made, so even unesco has laid down rules for the tribe, which can now communicate with the outside world, but visitors are not allowed to bring them anything modern to protect its traditional culture. Living in the wilderness, the tribe chose to share. Local men are the main bearers of food sources, and their daily duty is to go hunting, bring prey back to their homes and distribute it uniformly. Women, on the other hand, compile clothes and traditional jewelry, take care of their children and pick fruit. Because the processing is not equal, men will distribute more food, while women will be less. But "sharing everything" also includes women, although monogynous, but the women here can not refuse the demands of other men, also because the population withered badly. As a result, women will choose to fatten their buttocks in order to please. Ministry, the aesthetic here is "fat buttocks for beauty ", if women are born" beautiful "some, get a better life. It is difficult to criticize such a life, after all, the development of each region is different. I don't know how you rate this primitive tribe in Africa?
