The "Guns、Bacterial and Iron: Fate of Human Society "was first published in 1997，and won the Pulitzer Award in 1998 and the Royal Society Science Book Award。The book aims to clarify the Aboriginal people in the Americas、Africans and Australian Aborigines and Europeans and Asians in historical development。Dimmond thinks，The unique main axis of East Eurasia and Eurasia make domestication practice、Writing system and other important cultural innovation results can spread quickly，Gives the Eurasian mainland more significant politics、Technical and military advantages and faster development speed。

Axis of Orientation Hypothesis bet365 Play online games proposed by Dimmond received wide attention，But still lacks a quantitative test of its basic assumptions。Recent，Cross -disciplinary Research Team of the Institute of Evolution, the Institute of Evolution, the University of St. Louis, Washington University and Germany.、Comprehensive data sets of language and ecological differences，The authenticity of the direction axis hypothesis is tested globally。First，Researchers use the minimum cost path algorithm to find the difference between the temperature and drought conditions of different society to the minimum path。Next，Researchers calculated the distance and cost of the path，It is used to measure the ecological obstacles faced by culture between two society。

This study has quantified 54 cultural characteristics，All aspects involving Bet365 lotto review cultural development and social life，Ru Life、Residential Ecology、Property Rules、Marriage and relatives、Community organization、Politics、Labor and rituals, etc.。Dimmond mentioned in the book，Cultural innovation results are easier to spread in similar environments，Society similar to latitude has a more homogeneous environment。So，Researchers focus on the difficulty of how the environmental parameters related to latitudes affect cultural characteristics。The part of the research is found to be consistent with Dimmond's conclusions，That is environmental factors、Terrestrial and travel costs for a variety of cultural characteristics (dominated by living method、Home Animal Type、Political complexity characteristics, etc.) The spread of the transmission played a Bet365 lotto review restricted role。but but，Although the closer the ecological environment, the more likely to have the same cultural characteristics，But research pointed out，The main corridor of cultural communication in Eurasia is not more ecological homogeneous than other regions。This latest discovery is contradictory with Dimmond's assumptions。The research team subsequently lists 16 key areas worldwide as the centers of agricultural origin.，Comparison and analysis of environmental obstacles encountered by culture in region。Research results show，Even in the same continent，The severity of environmental disorders also has differences。The influence of the geographical environment mechanism is important，But the direction of mainland main axis does not uniformly control the potential of cultural communication。

bet365 live casino games Max Planck's Institute of Evolution of the Institute of Humanology, Russell Gray，Geographical environment and genetics、Ecological factors are as important，But cannot fully determine the trajectory of cultural communication and development。Carlos Botero, an associate professor of the Department of Comprehensive Biology at the University of Texas University, said，Researchers do not think that they have found accurate answers that can test the development speed differences in different regions。The original intention of the research is，Through a new perspective based on quantitative data and in -depth analysis，Use existing tools and data to test the important views that affect the public's understanding of history，Especially those perspectives that explain complex history bet365 Play online games with a single factors。This indicates，Even if a theory has great attraction，The academic community also needs to fully verify it。
