Canadian History 30 F SCIENTIFIC EVIDENCE OF ORIGINS

Land Bridge Theory Bering strait is a waterway that separates North America from Russia It covers a submerged landmass that was above water during the last ice age when most of Canada was covered by a thick ice sheet

Land Bridge Theory Scientists propose that people used this bridge to migrate from Asia Throughout the next thousands of years these people migrated through the America’s Archaeology suggests the migrations occurred 25, 000 -12, 000 years ago

Radiocarbon Dating Radiocarbon dating is a way of dating objects found at archaeological sites Radiocarbon dating has raised questions about the land bridge theory and makes some scientists believe that other migrations may have occurred

Monte Verde, Chile Artifact findings at Monte Verde, Chile appear to pre-date evidence of fist people in North America by about 1, 000 years

Other Theories Crossing at the Bering Strait when it was covered with ice Ocean crossings with landings at various points along either coastlines Early ocean travelers may have moved from island to island settled in South America long before Bering migration The Solutrean theory suggests people may have migrated from Western Europe during the ice age

In 2005 the National Geographic Society launched the Genographic Project clip 2 mins Its goal was to map historical human migration patterns based on collecting DNA evidence from hundreds of thousands of ppl from around the world. DNA Testing

Genographic Results The DNA evidence from this group suggests that all human beings descended from Africa starting about 60, 000 years ago

First Nations Controversy It is considered a controversy because it challenges traditional creation stories In some communities, Elders have asked people not to participate. Some First Nations have been asked to have land claims settled first before participating in the project

Evidence of Manitoba’s Past Lockport has evidence of agricultural settlement along the banks of the Red River Large storage pits, bison bone tools, ceramic pots, and bits of burnt corn (some artifacts up to 3, 000 years old) This evidence suggests the use of agriculture as well as interaction with First Nation groups further to the south

Evidence of Manitoba’s Past Stott family farm on the Assiniboine River 8 km west of Brandon Region had been used for years by various bison hunting communities Duck Bay site has evidence dating back 800 years Blackduck pottery with clay containers and advance techniques
