		| Scope | Life on Earth evolves through 46 Ba Earth history. Organisms evolve in relation to both Earth's interior and exterior activities. Biotic activities also should give strong influences to Earth's environments. We would like to describe biotic history on Earth and discuss how biotic system evolve in relation to Earth's environmental systems and interior activities during the session. |
