I recently read an article in the newspaper entitled, "Meteorite offers clues to life's origins." The article originally appeared in the Washington Post and was very interesting. It was discussing the tendency of amino acids found in living things to configure themselves in a "left-handed" configuration rather than randomly right- and left-handed as would occur in non-living systems. Very intriguing!
What do you think about the possibility that life began somewhere else in the universe and was "seeded" here on Earth by meteorites? Read the article and see what you think. If you're interested in some extra credit, come talk to me and we'll see what we can work out.
