Wham, Bam, Thank You Solar System

Nobody wants to be hit on the head with a ten-mile asteroid. But what if giant impacts are actually good for life in the long-term? I contemplate that strange possibility over at Wired.com. Check it out.

    what if giant impacts are actually good for life in the long-term?

    Don’t overlook the probability that these meteorites (as well as comets) actually brought life forms to the earth from elsewhere with all the information already present, possibly in the form of DNA bearing spores.

    That seems much more likely than life evolving de novo from the chemicals present in the primordal environment.
