Extremophiles: Weird Life - David Toomey

When movies imagine life in deep space, their creatures generally look hominid - George Lucas' Chewbacca the Wookie and James Cameron's Na'vi people aren't dissimilar enough from humans that we can't recognize them as other beings. But David Toomey says that Douglas Adams may have been closer to reality in his book, The Hitchhiker's Guide to the Galaxy when he described hyper intelligent shades of the color blue: they're strange beings that, unless scientists look carefully, might not be carbon-based, like most of the other life on our planet. Toomey's book Weird Life explain that unless we look very carefully and broadly for life out in space, we might not recognize it when we see it.
