Photosynthesis and the Oxygen Revolution • Most atmospheric oxygen (O 2 ) is of biological origin • O 2 produced by oxygenic photosynthesis reacted with dissolved iron and precipitated out to form banded iron formations AP Biology © 2011 Pearson Education, Inc.
• By about 2.7 billion years ago, O 2 began accumulating in the atmosphere and rusting iron-rich terrestrial rocks • This “oxygen revolution” from 2.7 to 2.3 billion years ago caused the extinction of many prokaryotic groups • Some groups survived and adapted using cellular respiration to harvest energy AP Biology © 2011 Pearson Education, Inc.
