First Martian life likely broke the planet with climate change, made themselves extinct

Ancient microbial life on Mars could have destroyed the planet’s atmosphere through climate change, which ultimately led to its extinction, new research has suggested.

The new theory comes from a climate modeling study that simulated hydrogen-consuming, methane-producing microbes living on Mars roughly 3.7 billion years ago. At the time, atmospheric conditions were similar to those that existed on ancient Earth during the same period. But instead of creating an environment that would help them thrive and evolve, as happened on Earth, Martian microbes may have doomed themselves just as they were getting started, according to the study published Oct. 10 in the journal Nature Astronomy.

The model suggests that the reason life thrived on Earth and was doomed on Mars is because of the gas compositions of the two planets, and their relative distances from the sun. Being farther away from our star than Earth, Mars was more reliant on a potent fog of heat-trapping greenhouse gases, such as carbon dioxide and hydrogen, to maintain hospitable temperatures for life. So as ancient Martian microbes ate hydrogen (a potent greenhouse gas) and produced methane (a significant greenhouse gas on Earth but less potent than hydrogen) they slowly ate into their planet’s heat-trapping blanket, eventually making Mars so cold that it could no longer evolve complex life.

The scientists believe their findings suggest that life may not be innately self-sustaining in every conducive environment it pops up in, and that it can easily wipe itself out by accidentally destroying the foundations for its own existence.

I think it was that guy who landed on the Bugs Bunny show.

[EastTexasTraveler]

Absolute nonsense.

[alstewartfan]

First they were knocking off Martians; now Whitey is looting Wawa stores in Philly. A long history of racist disgrace!

[nevergore]

Have they ever found a single Martian microbe?

[DoughtyOne]

Some of the stuff hitting the fan these days, makes me
lower my face and shake my head.

Nice Science there Fiction...

[tomkat]

Apologies if the point’s already been made ad infinitum,
but why the hell is this nonsense in ‘Breaking News’ ?

[SisterK]

not the Bee?

[P.O.E.]

likely

[SunkenCiv]

Nah. Thanks Oldeconomybuyer, glad you post these.

See Post 91. I don’t think y’all want to start an argument. ;-)

So “billions of years” of random chance finally generate life that makes it upward to the microbial level, and that life’s very existence extinguishes it. Seems like a big problem for the evolution believers.

LOL

[tomkat]

Oh well, it’s about bedtime anyway . . .

[refreshed]

Pure fiction.

What did Marvin the Martian say??

[RaceBannon]

I have posted actual breaking news articles that lasted less than an hour. And this stupid story is been in the breaking news for 6 or 8 hours right now.

[ASOC]

Boom!

How does a group of beings turnoff an entire geomagnetic field.

What a bunch of maroons

[dragnet2]

My theory is the martian microbial life was gay and the microbes never reproduced and they became extinct. Climate change had nothing to do with it.

[Does so]

Doesn’t somebody have to come up with microbes on Mars first?
