The Martian Virus

"Just what kind of harm a Martian virus could cause to Earth is unknown, but if history has any lessons to teach, there could be cause for concern." This is the type of question physical sciences professor Andre Meyers grapples with in his novel, "Mayan Mars." This is just a review of the novel but it got me thinking about the dangers we could be facing when discussing research on Mars. Are we immune to Martian biology? Is there some virus on the planet that has kept it from evolving like Earth? Just thought this was an interesting read.
