Oldest fossils?

Where did life begin on Earth? In deep sea shelves or in shallow seas? The case seems to have been reopened with the discovery of the oldest-ever specimens of deep-sea microbes so far. These fossils, found in a Chinese mine, are 1.43 billion years old. That seems pretty ancient, but they are juvenile compared to the 3.5 billion-year-old stromatolites found in Western Australia, which seem to indicate that life began in shallow seas. So the jury is out on that one.

  1. Shallow water such as coastal sea would seem the most likely place for life to start. Water, food, sunlight … it’s all there.
