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.

Modeling studies consistently prove that either very few scientists are capable of creating accurate models, OR (and this is more highly likely) creating accurate models is entirely NOT the point, because accurate models would not yield the desired result.
Mars doesn’t have a magnetosphere.
Martian bug farts.
NOT. BREAKING. NEWS.
So instead of “evolve or die,” it’s “evolve and die.”
1. It's not easy being Green
2. Go Red and your dead
There is NO PROOF that life existed on Mars, and these morons just ASSUME there was, and then they ASSUME it's extinct, then they just ASSUME they know why.
I mean, just go whole hog and assume the planet was alive with unicorns and leprechans.
Man...we need to somehow package climate change as a weapon.
Oh puleeze
“Kelp, people just don’t like teachers blowing up their kids!”
I was going to post the same thing. A strong Magnetic field is vital for a planet to have an atmosphere, as well as protecting life from solar radiation.
I just don’t know about the proclamations of the new, government paid religious-sciencists.
Something seems, not scientific…
I posted in Chat. Not Breaking News.
The Bee has become redundant.
I smell bullshit.
These jerks will make up anything in order to feed off the taxpayers trough. No theory is too far fetched when they want more taxpayer grant money.
What a racket.
“Is that why Mars is radioactive?”
Apparently the microbes had a miniature nuclear war also.
Maybe, maybe, maybe...
Possibly, possibly, possibly...
Perhaps, perhaps, perhaps...
Could of, could of, could of...
Another load of crappola.
