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.

Three words...sun screen
So there theory is it was “anti-global warming”?
These people have no shame at all when it comes to making things up. Scientist’s have turned into political Hollywood screen writers.
These people are nuts.
When they broke the planet, there better have been a big KA-BOOM
“carbon dioxide...is a gas, man”
Nutty Professor reference!
Nope. In fact, it’s cold as hell and there’s no one there to raise them if you did . . .
No matter how long it’s been the rusty SUVs and large landfills should still be there and visible. Right? I mean scientists are always finding things they tell us are millions of years old. Where are the old out-houses,piles of bones, out-door kitchens and the remains of the foundations of the large cities?
Oh what Tommyrot! it was obviously a lack of diversity that killed life on Mars! Martians were simply not inclusive enough!
You think I am lying??? Well, have you ever seen a rainbow on Mars??? I thought not!
The inconsistency here is that this is not the way the evolutionists tell us their theory works. According to their theory a higher life form wins out and then another yet higher life form develops.
Evolution of mere matter to living reproducing microbes is still impossible.
Same, and I’ve seen a Biden video.
“The model suggests” that with another $250,000,000 grant we can research that problem to within an accuracy of +/- 100%
Mars' lesser gravity (than earth's) is capable only of holding a heavier atmosphere than earth's. That's it. More than 90 percent is carbon dioxide, but since the MSN and today's "theorists" think carbon dioxide is a pollutant, then one could alternatively claim -- theorize -- that the "pollutant" killed off any possible oxygen-producing life forms. Which would also be bunkum.
Simple. Mars is smaller and less massive than earth and therefore does not hold lighter gaseous elements. Its gravity compared to the earth is only about 40 percent.
CO2 is 44.02, while oxygen is "lighter" at 31.99 and nitrogen even lighter at 28.01. So earth holds about 78 percent nitrogen in its atmosphere while Mars simply cannot. Ditto with oxygen.
Trust MSN to print "scientific" theories without basic science behind it. The idiotic article hints that there was an atmosphere similar to earth's which got "eaten away." Loony. Gravity sucks. Less gravity sucks less....
Microbial life?? Really??
Those selfish, short-sighted microbes! If only there was a microbe version of Greta Thunberg to put them all in their places! If only the progressive side of Microbia had better news coverage they might have avoided the CO2 generated by their tiny SUVs, flagella-spray, and failure to trade in bioluminescent lighting for LEDs.
Oh, the huge manatee!
Not the Bee.
“Is that why Mars is radioactive?”
No.
