... but, on Mars, it just doesn't seem that likely, whatever the Huffington Post's Buzz Feed column might say If you've seen the story already, then you won't need to be told: apparently, an image returned from the Opportunity rover includes something which looks like wood on the surface of Mars.
Like seeing Bigfoot on Mars back in January, it's a fairly safe bet, although for different reasons, to say that you are not seeing what you think you are seeing.
If it were a rock formation on Earth, most people would say: "yes, looks like a rock". If it were a piece of petrified wood on Earth, that would be explicable and understandable too.

Let's just say this quickly, and be done with it: there's no wood on Mars. It's like finding life on Mars: sometimes, you have to wonder on which end of the telescope the intelligence is to be found.
