It seems to us that the problem of Beringia is a kind ispytatelskoy training ground, where the interests of a wide variety of sciences, hypotheses, sometimes quite nonconcordial each other (which you probably have already had the opportunity to be sure) and yet allows to go to the common goal of every scientist - the objective truth that exists outside the struggle of schools, currents and traditions of a particular academic discipline, and so on.. Beringia "gateways"? The settling of America The problem is inextricably linked with the environment of ancient man. People Paleolithic did not sow, do not reap, not keep livestock. To survive, they had to hunt - at land and marine animals at large, such as mammoths and small, such as shrews and lemmings. It's like sets conditions for the existence of ancient people: where there is no production, will not live, and primitive people. But the existence of animals, in turn, is defined by natural conditions: terrain, vegetation, climate, etc. But here, everything is interconnected:.. Klimatopredelyaetsya astronomical and other "space" causes the number of animals may depend on whether they are destroyed ruthlessly or not. In short, space, land vegetation, fauna and the human race, "liberated" from the animal world, linked cybernetic feedback. And the relationship is not linear and complex, mutual dependent on many parameters. There is little wonder then the variety of hypotheses that push researchers seeking to resurrect the "things of bygone days", which took place thousands of years and tens of thousands of years ago on the "edge of the known world."
