Climate changes had a profound impact on the hominin way of life. In southwestern Europe, for example,
A. the melting of the ice sheets with the end of the Wrm glacial period gradually pushed big game farther north, pressuring hominins to use a greater variety of foods.
B. hominins turned to a more specialized diet based on big-game meat after the glacial retreat.
C. hominins began a sedentary life after the end of the Wrm glacial period, forming the first villages in human history.
D. the melting of the ice sheets with the end of the Wrm glacial period caused animal diversity to drop, challenging hominins to shift their diets from meat to coarse grasses.
E. hominins were forced to migrate northward during the Wrm glacial interval.

D. Researchers calculate that it would have taken from 600 to 1,000 years for the first Americans and their descendants to travel by land from the southern part of the Canadian ice-free corridor to Tierra del Fuego at the southern tip of South Americaa distance of more than 8,680 miles.
E. The first migration of people into the Americas reached the continent's southwestern coasts from the Pacific islands.
