Zombies Responsible for Life on Earth?

It’s called Necropanspermia and stop your sniggering right there! The idea that life could have arrived on Earth as a hitchhiker has long been around, and some have even proposed that life evolved on Mars, and was transported here.

Regardless, it now seems that we may have to rethink our term, Post-Vital, as it now seems that Zombies could theoretically be Prime-Vital. In any event, this is awesomely cool to think about.
