Meet the Endoterrestrials - The Atlantic
Even as Onstott awaits those results, he is starting to consider an even more radical possibility: that deep-dwelling microbes don’t just feed off of earthquakes, but might also trigger them. He believes that as microbes attack the iron, manganese, and other elements in the minerals that line the fault, they could weaken the rock—and prime the fault for its next big slip. Exploring that possibility would mean doing laboratory experiments to find out whether microbes in a fault can actually break down minerals quickly enough to affect seismic activity. With a scientist’s characteristic understatement, he contemplates the work ahead: “It’s a reasonable hypothesis to test.”

Superhabitable planet - Wikipedia
They propose clarifications because a circumstellar habitable zone (HZ) is not enough to define a planet's habitability.[3] Heller and Armstrong state that it is not clear why Earth should offer the most suitable physicochemical parameters to living organisms.

Was There a Civilization On Earth Before Humans? - The Atlantic
It’s not often that you write a paper proposing a hypothesis that you don’t support. Gavin and I don’t believe the Earth once hosted a 50-million-year-old Paleocene civilization. But by asking if we could “see” truly ancient industrial civilizations, we were forced to ask about the generic kinds of impacts any civilization might have on a planet.
