ANCIENT EARTH TRANSFORMED BY ALGAE. “Algae systematically collected solar energy, sequestered carbon atoms and released oxygen. Moving at the incredibly slow rate of one tiny molecule at a time, algae transformed the harsh carbon dioxide atmosphere that could not sustain life to an oxygen atmosphere that supported life. Algae took another 3 billion years to create sufficient oxygen to support other forms of life because land plants evolved from algae only about 500 million years ago.””
