Option 'B' = changes in climate, had the greatest impact on pre-historic man.
Changes on the weather forced men to move periodically or cyclically, usually returning to their original location at various times. When they moved to colder climates, they would make clothing out of animal skins, to protect themselves. When the nomads learned how to plant, they didn't need to search for other places anymore.
Research by some scholars provides population estimates of the pre-contact Americas to be as high as 112 million in 1492, while others estimate the population to have been as low as eight million. In any case, the native population declined to less than six million by 1650.
I believe there is a book on the matter as well. Good luck. :)

beliefs, chances are you would have settled in Pennsylvania. The father of
William Penn was a Quaker and a charter was granted to William Penn by the
crown of England to name a colony after his father. Pennsylvania is now just 14
miles away in the south of Philadelphia. This is the main reason why it is
correct to feel that Pennsylvania is the place to practice Quaker religious beliefs
for any person.
