白令海峡位于亚欧大陆最东点的俄罗斯杰日尼奥夫角和美洲大陆最西点的美国威尔士王子角之间，西经169°40′，北纬65°35′，约80千米宽，深度在30米-50米之间。海峡连接北冰洋、楚科奇海和白令海，是亚洲和北美洲的分界线。名字来自丹麦探险家维他斯·白令，他于1728年在俄国军队任职时候穿过白令海峡，第一次穿过北极圈。
但是有没有一次或几次大移民浪潮是穿过白令海峡到达美洲的呢？
But was there one major wave of migration across the Bering Strait into the Americas, or several?
从这个证据可以推断，横跨白令海峡的大型移民潮曾经有过三次。
From this evidence it was deduced that there had been three major waves of migration across the Bering Strait.
最近的证据支持了一个与长期存在的理论对立的观点，该理论认为，在1.1万至1.2万年前，美洲是由从白令海峡沿中大陆无冰走廊向南迁移的人殖民的。
Recent evidence favors a rival to the long-standing theory that the Americas were colonized 11,000-12,000 years ago by people migrating south from Beringia along a midcontinental ice-free corridor.
