More Clues to the Oldest Fossils Ever

The video discusses recent scientific discoveries of ancient life, including microfossils found in Quebec and potential evidence in Greenland's Isua greenstone belt. It highlights the use of vibrational spectroscopy to identify organic material in ancient rocks. Additionally, the video addresses ocean acidification, explaining how increased CO2 levels affect ocean chemistry. Researchers at Caltech propose using the enzyme carbonic anhydrase to accelerate natural chemical reactions, potentially mitigating acidification effects. This research could enhance the ocean's bicarbonate buffer, offering a partial solution to rising CO2 levels.
