new research has recently discovered water droplets in mineral deposits that are believed to be from an ancient ocean that existed around 600 million years ago in the Himalayas. Scientists from the Indian Institute of Science (IISc) and Japan's Niigata University said this discovery suggests that there may have been a major oxygenation event in Earth's history.
They believe that the Earth may have been covered by thick sheets of ice between 700 and 500 million years ago, known as the Snowball Earth glaciation. This event was followed by the Second Great Oxygenation Event which led to an increase in the amount of oxygen in the Earth's atmosphere which led to the evolution of complex life forms.
