University Park, Pa. -- A switch from predominantly undersea volcanoes to a mix of undersea and terrestrial ones shifted the Earth's atmosphere from devoid of oxygen to one with free oxygen, according to geologists."The rise of oxygen allowed for the evolution of complex oxygen-breathing life forms," said Lee R. Kump, professor of geoscience, Penn State.Before 2.5 billion years ago, the Earth's atmosphere lacked oxygen. However, biomarkers in rocks 200 million years older than that...
