Essays on Land Bridge

Section

All Sciences, whether Physical, Social, or a combination of the two (like Anthropology), are based on hypotheses and theories. Some of the unlikeliest scientific theories have arisen from hypotheses that were considered insane at one point. In the world of Anthropology, the situation is no different.

Governments were so thrown apart by statements like this that people were decried as heretics, beheaded or sent into exile. These scientists went against what was mainstream thinking ...

Abstract

The Great American Interchange lasted for about two million years between North America and South America. The objective of the essay is to look at the symmetrical results of the great American interchange in the beginning and how the interchange became asymmetrical after time progressed. The unbalanced nature of the interchange offers a model to explain the asymmetrical results of the land-mammal interchange between the two Americas. Both Geological and biological data are looked into the get insights the past and present distributions of fauna.

This essay explores how the United States which began as 13 separate colonies formed a distinctive nation of its own. It traces the early evolution of the people of America and the path to American independence from the colonial power. 1.

As the glaciers melted, the land bridge was submerged, leaving them trapped on this side of the Bering Sea. Those people of Central America i.e., Maya, Aztec & Incas, became centers of innovation and cultural diffusion. They all ...

According to the theory of Land Route Theory, humans migrated from Siberia to Alaska across a land bridge that were exposed before the start of the Ice Age. It was around 22 to 25 thousand years ago that humans crossed the Bering land where it served as a link to the New World. On the other hand, the Coastal Route hypothesis suggests that humans from East Asia must have traveled ...
