Beneath your feet, a living planet

"Contrary to long-held assumptions, Earth’s interior is not barren. In fact, a majority of the planet’s microbes, perhaps more than 90 percent, may live deep underground. These intraterrestrial microbes tend to be quite different from their counterparts on the surface. They are ancient and slow, reproducing infrequently and possibly living for millions of years. [...] Subsurface microbes carve vast caverns, concentrate minerals and precious metals and regulate the global cycling of carbon and nutrients. Microbes may even have helped construct the continents, literally laying the groundwork for all other terrestrial life." The Mysterious, Deep-Dwelling Microbes That Sculpt Our Planet, an excerpt from Becoming Earth, by Ferris Jabr.

I’m disappointed that Tommy Gold’s Deep Hot Biosphere got a nod, his most controversial claim, that microbes are the source of fossil fuels, isn’t addressed

Tommy Gold’s Deep Hot Biosphere

That sounds like title of either a disco funk album, or a porn film.

The most outstanding feature of life’s history is that through 3.5 billion years this has remained, really, a bacterial planet. Most creatures are what they’ve always been: They’re bacteria and they rule the world. And we need to be nice to them.

Wow. Also thanks for the gift link. TFA is a great example of the NYT at its best. Would that their political reporting and punditing could rise to that level.

It's been a long time since I was a life-science major, but I retain memories that in the '80s there was a field of study opening up in endolithic lichens. That is, plants that live inside of rocks. That and the stories of the wild biological communities around deep-ocean vents are clues about what TFA describes, but wow, I had no idea.

Slow life? Don't trust any protomolecules it sends our way.

deep :-) Hazen's Symphony in Carbon also looks interesting [gbooks]

the obvious solution would be to drill for more microbes.

Just a couple of weeks ago, there was this Metafilter post about how the atmosphere is full of life, much higher up than you might believe. Together, these two posts paint a beautiful picture of a living planet.

Thank you Termite! I had missed that post.

concentrate minerals and precious metals

Next link in the supply chain- Gold Digging Ants. (Or marmots.)
