FW 104 CSU EXAM 2 QUESTIONS AND ANSWERS 100% PASS Pleistocene Overkill Hypothesis Proposes that human activity, particularly overhunting, led to the extinction of large mammals at the end of the Pleistocene around 10,000 years ago as human populations expanded. Market Hunting Era (Era of Exploitation) Spanning from 1850 to 1899, this period reflects a belief in abundant wildlife resources among new American settlers. It resulted in widespread hunting and the loss of species like...
