If lifeforms ever had a chance to develop on the Red Planet, they may all be dead now, due to the fact that the planet has been plagued by intense drought for at least 600 million years. This actually makes a lot of sense, even when considering that water-ice still exists at Mars' poles.
At this point, the sur... |

In addition to being extremely dangerous to humans on their own, many microorganisms also display the ability to mutate extremely fast, so that they can adapt to new, unexpected situations at a moment's notice. The capability was observed as scientists monitored microbes in a new experiment.
