Question 2

How did modern humans take advantage of global climate change to expand their range?

A. During major glacials, with so much water frozen in ice, land bridges formed, aiding human colonization of new areas such as Australia by 46,000 B.P. and the Americas perhaps by 18,000 B.P.
B. During interglacial periods the seas rose, encouraging human exploration of the oceans, such as the case of the Pacific islands from Asia by 46,000 B.P.
C. Warmer periods forced people to adapt their diets to a smaller range of staples, in turn forcing them to move to ensure that these staples remained part of their diet, such as the case of the colonization of Sahul by 50,000 years ago.
D. During major glacials, with so much of the earth's soils too frozen for agriculture, humans had to turn to hunting and foraging, which in turn forced them to be on the move once they depleted an area of its food resources.
E. During interglacial periods the sea levels dropped, encouraging human exploration along the coasts, leading to unexpected discoveries such as the case of the Pacific islands from Asia by 46,000 B.P.
