Dark Oxygen Discovery Follow-Up - Addressing Comments and Questions

Explore the fascinating follow-up to the "Dark Oxygen" discovery in this informative video. Delve into the formation of oxygen-producing polymetallic nodules at the seafloor, their recharging process, and the fate of hydrogen during water electrolysis. Learn about the potential for synthesizing these nodules, their oxygen contribution compared to photosynthesis, and the implications for marine life. Investigate the role of dark oxygen in the origin and evolution of life on Earth, including its potential impact on animal evolution. Gain insights into the requirement of oxygen for nodule formation and the presence of ancient enzymes. This comprehensive exploration addresses viewer questions and expands on the groundbreaking discovery that challenges our understanding of the global oxygen cycle.
