The document discusses several hypotheses for what caused the mass extinction of megafauna (large animal species) at the end of the Little Ice Age period between 1300-1850 AD. The main hypotheses presented are: 1) "Overkill" - Early human hunters in North America over-hunted megafauna species when they first arrived, driving many to extinction. 2) "Overchill" - Rapid climate changes at the end of the ice age, particularly a cold snap between 12,900-11,500 years ago, stressed megafauna populations and habitats leading to widespread die-offs. 3) "Overill" - A virulent "hyperdisease" brought by the first humans

7. How does the cost of grain change in Germany between 1500 to 1700? Are there years when grain is inexpensive and other years when it is expensive? What do you think might cause changes in the price of the grain?
