Guns, Germs, and Steel Part 5

We have been watching the movie and this is the fifth class day we are watching it. The area in the middle east with good crops and animals is called the fertile crecent. When the animals helped people with crops there was more surplus. This helped people sepcialize in different things. Climate and environment  changed and forced people to move. They moved to areas on the same latitude. Places with the same latitude have similar days length and climate. The crops and animals were spread rapidly through Europe North africa and Asia. Geography was a big part of how civilizations started and flourished.
