Planetary Scientists Discover That Mars Underwent a Great Oxygenation Event Billions of Years Ago - 12 Apr 2021

“This is a rather remarkable study with findings that will significantly impact how we understand the early evolution of terrestrial planets and their surface environments. The transition from a reducing to oxidizing atmosphere on Earth ~2.5 billion years ago was only possible because of the existence of life, as oxygen is a waste product of metabolic processes like photosynthesis. Without microbes producing oxygen, it would not accumulate in our atmosphere, and we could not be here. While there are certainly differences in the local conditions Mars and Earth have been subjected to during their evolutionary histories, my mind can’t help but start thinking about what Jiancheng’s results may mean for a potential early Martian biosphere,” Dr. McKenzie remarked.
