3. We ask so many questions, which leads us to so many answers, which leads us to more questions, which is why our world is based on knowledge.

5. Journey of Man The story of us is written in our blood. Often times, finding answers only leads to more questions. The first humans have been traced back to Africa through DNA testing. By following DNA markers in men we learn that through time humans have migrated from Africa to places like Asia and the Middle East.
6. Journey of Man Traditions often conflict with science because people want to cling to their old ways and not be faced with new information that might shake up their view of the world. Isolated peoples are being immersed into modern society and eventually our DNA path from Africa will be hidden again.
7. Catastrophe! By analyzing tree rings, David Keys theorizes that a huge natural catastrophe completely changed the world. In A.D. 535 a catastrophe occurred that was probably the result of a volcano. It affected many parts of the world in varied ways. Some the ways included failed crops, droughts, floods and disease.
8. Catastrophe! Continued The Bubonic Plague killed up to 10,000 people a day in Europe! Because of natural hardships, empires were invaded and weakened. Instead of all of the problems being isolated events, David Keys claims they all occurred because of a single event.
9. Guns, Germs, and Steel Jared Diamond explores why some places have an excess of materials or goods while some places do not. He tries to answer the question, “Why you white men have so much cargo, and we New Guineans have so little?” The answer begins with the stone age people of the Middle East who became the first farmers. They cultivated grains like wheat and barley and domesticated animals.
10. Guns, Germs and Steel Through the advancement of farming and domesticating animals, villages began to grow larger. As villages grew larger, food surpluses were created and more people were free to work on other things. Advancements were achieved because there were more people and resources to work on them. Places without natural resources cannot advance.
11. The Age Of Discovery Europeans began to explore the unknown in search of new trading routes and certain luxuries. Their explorations changed what people knew about the world and how they viewed it. Europeans wanted goods from Asia like spices, gold and silk.
12. The Age of Discovery Potatoes, corn and tobacco were crops that changed the world. Horses and cattle changed how people hunted and farmed. When horses were brought to America, the Indians used them to hunt with.
