The Dawn of Humans and the Effects of Climate on Civilizations. Major Concepts. Climatic changes produced distinctive flora and fauna that was adapted to cold weather. Among flora were the expansion of grasslands, tundra, boreal spruce forests, and hardwood forests. Lecture 3. Development of. Geological Concepts, Part I. Major Concepts.
