More Movie Watching

Today in class we continued watching the movie about Jared Diamonds' theories. One fact that I thought was interesting was that there are only fourteen animals that have been successfully domesticated. Most of these animals are big animals that weigh over 100 lbs. The animals are goats, sheep, pigs, cows, horses, donkeys, bacterian camels, Arabian camels, llamas, water buffaloes, reindeers, yaks, mithans, and bali cattle. All of these animals, except the llama, came from Africa or the Middle East. The movie began to talk about steel a little. The mentioned how steel is better than stone and is more productive. Also how the control of fire and learning how to use it to its abilities to create weapons, including steel.
