User: After hunting by European settlers, the bison population of 60 million was reduced to _______ of its original size. a. 1 : 60 b. 1 : 600 c. 1 : 6,000 d. 1 : 60,000

Weegy: The American Bison evolved from a species of large grass-eater that migrated to North America from Siberia 40,000 years ago. Before European settlement of the Great Plains, approximately 60 million bison existed in North America. [ [ The population plummeted to 1,100 as European settlers killed nearly every bison. Bison were shot for their valuable hides and for their meat which was a hot commodity for railroad workers. Railroads companies also encouraged "adventure" hunts where tourists would shoot bison from the train for sport. (Some suggest that this was actually part of an attempt to subdue the Plains Indians, who depended on the bison for food.) ] ]
