vol. 2, number 13, Panspermia

What the hell is Panspermia? The big idea is that life on earth has it's origin in biologically active material that somehow survived a trip across interplanetary or interstellar space. You may recall the controversy from several years back regarding some rocks of Martian origin found on Earth that seemed to contain trace evidence of biological activity inside. The pitch was that this rock demonstrated that life once flourished on Mars and rocks like these could have infected Earth with its earliest colonies of life. I like the idea a whole lot. Not because it greatly stretches the length of time available for life to crawl it's way out of chaos all on its own, but because it means we're all Martians after all.
