I spent months building this interactive timeline that puts 4.5 billion years of Earth history on a single canvas — geological periods, plate tectonics, magnetic polarity reversals, atmospheric oxygen, sea level, temperature, microbial life, plants, animals, human evolution, migrations, and civilizations — all synchronized on the same time axis.

Switch between log and linear scale. Zoom into the Cambrian explosion or pull back to see all 4.5 billion years. Click any event for details and images. Collapse the tracks you don't need.
