Document Summary

Three influential events that have shaped canada"s history: the arrival of the first people in north america, the colonization of north america by france and england, the influx of people from eastern europe. Hunters from the old world (the eastern hemisphere) were the first to arrive about 40,000 years ago. As the ice in north america began retreating 15,000 years ago, descendants of the hunters pushed further south. They crossed the bering land bridge that connects siberia to alaska. This land was exposed because sea level was much lower at that time. They travelled along an ice-free corridor that developed along the rocky mountain foothills. These first people were known as paleo-indians. They were descendants of the old world hunters. They commonly hunted mammoths with pointed spears. As mammoths became extinct, paleo-indians began shifting to a diet mixed with meat (buffalo and caribou), fish, and plants. The revised diet allowed them to remain in a specific geographic region.
