Thee Role of Natural Passages andChokepoints

Certain geographic features contaminate migration flows into narrow corridors, creating previdable routes that have been used for setnies. The Isthmus of Panama, the narrow strip of land connecting North and South America, has been a criticaal passageway bene pre- Columbian times.
