Unlikely. There's been no animal hosts on Mars, in which such a micro-organism might have evolved to threaten humans on Earth.
Not to say we shouldn't be careful for other reasons though. The bigger risk is the sudden extinction of entirely different branches of life, by more highly-evolved Earth-originating species.
- TaylorAlexander 7y agoI think the other person is saying that Earth bacteria could potentially wipe out Martian bacteria if the conditions are right. And that would be tragic.
- NeedMoreTea 7y agoThat was exactly my thought. We discover extraterrestrial life, and inadvertently wipe it out, or just swamp them with an invasive species, without getting a chance to study them before we mucked up their ecosystem. As you say it would be tragic, but also very typically human.
