[B-PT25_2PM1] Biotic history and its relation to the Earth history

Fri. May 2, 2014 2:15 PM - 4:00 PM 416 (4F)

Convener:*Isao Motoyama(Department of Earth and Environmental Sciences, Yamagata University), Takao Ubukata(Institute of Geosciences, Faculty of Science, Shizuoka University), Chair:Takao Ubukata(Institute of Geosciences, Faculty of Science, Shizuoka University), Isao Motoyama(Department of Earth and Environmental Sciences, Yamagata University)

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.
