QUES: Hunter-gatherers would eventually flourish all over the Americas, primarily based in the Great Plains of the United States and Canada, with offshoots as far east as the Gaspé Peninsula on the Atlantic coast, and as far south as Chile, Monte Verde.[citation needed] American hunter-gatherers were spread over a wide geographical area, thus there were regional variations in lifestyles. However, all the individual groups shared a common style of stone tool production, making knapping styles and progress identifiable. This early Paleo-Indian period lithic reduction tool adaptations have been found across the Americas, utilized by highly mobile bands consisting of approximately 25 to 50 members of an extended family.

How many members did the mobile tool-making hunters often have?
What is the answer?
ANS: 25 to 50 members

QUES: The specifics of Paleo-Indian migration to and throughout the Americas, including the exact dates and routes traveled, provide the subject of ongoing research and discussion. According to archaeological and genetic evidence, North and South America were the last continents in the world with human habitation. During the Wisconsin glaciation, 50–17,000 years ago, falling sea levels allowed people to move across the land bridge of Beringia that joined Siberia to north west North America (Alaska). Alaska was a glacial refugia because it had low snowfall, allowing a small population to exist. The Laurentide Ice Sheet covered most of North America, blocking nomadic inhabitants and confining them to Alaska (East Beringia) for thousands of years.

A small population could exist in Alaska because of it's lack of any significant what?
What is the answer?
ANS:
snowfall
