Fossils in Greenland suggest there was life on Earth 220M years before scientists thought.

Researchers found evidence for ancient life from a “newly exposed outcrop” of 3.7 billion-year-old metacarbonate rocks in southwest Greenland, according to the study.

The Guardian version of this story quotes an astrobiologist as saying, “…around the time that these ancient layered rocks formed in Greenland, Mars was itself a much warmer and wetter, and thus habitable planet.”. It’s unclear whether he was alluding to the Panspermia theory, or whether he was just trying to put these unimaginably vast numbers in some kind of fathomable perspective.

This reminds me of that female archeologist (cant think of her name), back in the 80s, she discovered some ancient site where they butchered animals for food, after doing the dating work, I believe she found they were MUCH older than anyone thought (around 300K yrs), everyone told her the dating was wrong, she was even asked to sign off on ‘fake results’ that were more inline with modern science and not so bizarre…Anyone know who Im talking about?

Wow! Now wouldn’t that be something.

I think he was alluding to the notion that life on Earth can survive wherever there is water. Regardless of the chemical environment. Regardless of the presence or lack of sunlight. Even if the pH is horrific, or the pressure unimaginable, or the radiation exposure intense, life has been found on Earth.The Greenland rocks are supportive of that notion, which has shaped the search of life outside of Earth.

Since abundant water existed on Mars at about the same time in the solar system’s history, the Greenland rocks are encouraging to persons, such as this astrobiologist, who looking for signs that life existed on Mars.

Had no idea that you could grow grass in ice.

Cynthia Irwin-Williams?
Virginia Steen-McIntyre?

They were both involved with the Hueyatlaco, archeological site in the Valsequillo Basin near the city of Puebla, Mexico. It was known for its abundance of animal fossils. Irwin-Williams described it as a “kill site” where animals were hunted and butchered.

“After excavations in the 1960s, the site became notorious due to geochronologists’ analyses that indicated human habitation at Hueyatlaco was dated to ca. 250,000 years before the present.”
