Ocean chemistry helped early life keep breathing

Original: How ocean chemistry helped life keep breathing

Researchers at the University of California, Riverside report that shifts in ocean chemistry played a key role in allowing early life to keep producing oxygen, sustaining Earth's breathable atmosphere. The study, covered by Phys.org, suggests chemical changes in seawater helped marine microbes maintain oxygen production over billions of years. The findings offer new insight into how the planet's atmosphere became stable enough to support complex life.

Why now: A new university study on ocean chemistry and Earth's oxygen was just published and is drawing wide science coverage.
