Guns, Germs, and Steel presentation day

Today during class, some student got to present their presentation from thursday. We were assigned to a topic we had to research on and have to present it. Our group didn’t have a chance to present because there wasn’t enough time. We had the group with the topic food and disease to present. The group with food talked about the animals cattles, goats, horses, sheep, pigs, llamas, and zebras. The group with the topic disease or germ, talked about smallpox and malaria. 

Notes (for our group):
Food-
- Wheat: Cultivated by the earliest Neolithic farmers in the hills and valleys of Syria, Jordan, Turkey and Iraq over 13,000 years ago, wild-growing wheat has since changed beyond recognition. In the wild, as it still grows in those places today, wheat evolved to shatter in the late summer breeze, spreading its tough-coated seeds far and wide. 

- Corn: Corn's wild ancestor, teosinte, is native to southern Mexico, and formed the staple of the earliest agricultural communities throughout the Americas. From its origins in central America, the crop spread up the western coast to northern America, and penetrated the jungles of Panama and Colombia to reach the fertile terraces of the Inca Empire in the South.

- Rice: Rice is believed to have been domesticated nearly ten thousand years ago in China. Related to wheat and other wild-growing cereal grasses, the plant grows to around four feet and thrives in submerged land in the coastal plains, tidal deltas and river basins of tropical, semitropical, and temperate parts of the world.

- Sorghum: growing as high as 15 feet, sorghum is especially valued in hot and arid regions of the world, for its natural resistance to drought and heat. Its grains are usually mashed into a pulp, boiled and eaten, while its tough stalks can be used to make brooms and brushes.
