Maybe life is older than we thought!

3.77-billion-year-old fossils stake new claim to oldest evidence of life

Life on Earth may have originated in the sunless depths of the ocean rather than shallow seas. In a new study, scientists studying 3.77-billion-year-old rocks have found tubelike fossils similar to structures found at hydrothermal vents, which host thriving biological communities. That would make them more than 300 million years older than the most ancient signs of life on Earth—fossilized microbial mats called stromatolites that grew in shallow seas. Other scientists are skeptical about the new claims.

Ah, thanks for posting that, Gloucester. Tantalizing story.

Facsinating.
