The Bering land bridge is a postulated route of human migration to the Americas from Asia about 20,000 years ago. An open corridor through the ice-covered North American Arctic was too barren to support human migrations before around 12,600 BCE.
As temperatures warmed across Beringia beginning around 18,000 years ago, very small numbers of people pushed into Northeastern Siberia and onto the land bridge. Perhaps they encountered the descendants of the Beringian standstill population, also on the move. They brought with them a stone technology from Siberia, Mongolia, or even Japan that was ideal for hunters traveling in very cold environments. Their barbed hunting weapons were comprised of small, very sharp “microblades” knocked off from lumps of fine-grained rocks. They also hunted with spears tipped with nicely flaked stone projectile points. Fortunately for archaeologists, we can trace the distribution of these distinctive technologies over very long distances. Both the edge-shaped blanks used to make microblades and small, teardrop-shaped spear points appear in Alaska as early as 14,000 years ago.

The author suggests that anthropology is unique among other disciplines such as economics or history because our perspective begins with statistics.
<u>Explanation:</u>
Anthropology means the study of human and their development.
The study of humans may differ from place to place. This is study is based on the statistics.
Statistical data can be analyzed and they can be found to which period this material belongs to. Due to this history can be found.
From the History only Economics can be found. Statistical data place a major role in creating the history and the economic status of material, country or even the whole world.
In "Democracy, Climate Change and Global Governance" authors Held and Hervey argued that modern democracies are less able to respond to complex global issues because they suffer from interest group concentration. By this they meant that our political system requires politicians to respond to small, well organized interest groups with narrow interests.True
