- 1. earth + fire = stone
- 2. air + stone = sand
- 3. earth + water = swamp
- 4. sand + swamp = clay
- 5. fire + clay = brick
- 6. fire + stone = metals
- 7. fire + air = lightning
- 8. lightning + swamp = amino acids
- 9. amino acids + swamp = bacteria
- 10. bacteria + water = algae
- 11. earth + algae = moss
- 12. moss + swamp = fern
- 13. moss + earth = grass
- 14. fern + grass = flowers
- 15. flowers + earth = trees
- 16. metals + trees = wood
- 17. wood + brick = incomplete building
- 18. sand + fire = glass
- 19. grass + earth = bamboo
- 20. metals + wood = tools
- 21. bamboo + tools = tube
- 22. glass + tube = spyglass
- 23. 2x bacteria = cells
- 24. cells + water = plankton
- 25. algae + plankton = fish
- 26. fish + swamp = amphibians
