This newspaper comprehensive foreign media reported the latest research results of scholars such as Paul Roscoe, a professor of anthropology at the Department of Anthropology at the University of Benen,。这项名为“人口密度和规模促进互动能力和国家的产生”（Population density and size facilitate interactive capacity and the rise of the state）Bet365 app download 的新研究，Power theory about political centralization (Power theory)，And this theory analyzes the dynamic changes in the power of the prehistoric society in the northern coast of Peruvia。The theory of power is considered，Population density and scale are key variables that regulate the interactive ability of political behavior.，The subject of political behavior uses interactive ability to build control of others。

Researchers use the total number of probability distribution from 8050 to 950 AD from 8050 to 950 AD.。During this period，Peru's political form Bet365 lotto review has changed from "Quasi-Egalitarianism" to the concentration of power at the national level。Some scholars have proposed，The population of the coastal area of ​​northern Peru is growing from 4050 BC to 750 AD，This study confirms this judgment。People who settled in the above areas were originally a flowing hunting collector or the earliest planter among the low -density population group，But some events that occurred between 2500 BC and 1850 BC promoted the interaction and resource sharing between these people。Push over time，They started farming land，Construction of irrigation Bet365 app download system，Weaken population liquidity。Final，The most primitive "national" formation in the world。

Researchers said，The rise in population scale and density has promoted the development of agriculture，Cultivated the subject of political acts interacts with others、Manage the ability of others，Concentration and hierarchical systems formed。This research also shows，You can use the total probability distribution to understand the impact of the population scale in the prehistoric society on the generation and development of power centers，But the degree of influence Bet365 app download still needs further research to determine。
