WORLD HISTORY

Detailed explanation-1: -Instead, early nomads might well have traveled by boat or at least along the coast from Siberia to North America, perhaps navigating arctic waters near today’s Bering Strait. The telltale evidence: ancient DNA from those early people that’s been coaxed, by powerful analytical technology, into revealing its secret.

Detailed explanation-2: -The Ancient Beringians separated from the ancestors of living indigenous people in the Americas about 20, 000 years ago. The new findings suggest they endured for several thousand years.

Detailed explanation-3: -Drought, flood, and temperature changes could certainly push people to move on. Climate change also affects the food supply, and anthropologists have assumed that people came to the Americas because they were following food on the hoof.

Detailed explanation-4: -The timeline for the Age of Discovery presumably starts with the Vikings. Several timelines assume that Scandinavian Vikings discovered the continent during their maritime explorations of the late 10th century, which later resulted in the Norse colonisation of Greenland and of L’Anse aux Meadows in Newfoundland.

Detailed explanation-5: -In the 1970s, college students in archaeology such as myself learned that the first human beings to arrive in North America had come over a land bridge from Asia and Siberia approximately 13, 000 to 13, 500 years ago. These people, the first North Americans, were known collectively as Clovis people.
