Today's lesson addressed the transition from nomadic tribes to sedentary lifestyles, communities, and ultimately civilizations. Essentially the lesson addressed the importance of agriculture in requiring people to stay in one place: to plant, tend, and harvest crops, allowing people to eat and thrive, leading others to join them in the formation of communities, eventually resulting in what we broadly call civilizations. Hunter was shown a number of short videos on the impact of agriculture in connection with this transition in various locales (Fertile Crescent, North America, and Mesopotamia). We also discussed the prosaic subjects of class requirements and grading.
