Archaea -- The Undead

Their usage of energy is so little that they may be called as "undead" rather than living organism. This is an exciting time for biologists as "Our whole concept of microbial evolution is up for grabs," Lake said. "People are realizing there is lots of exchange and gene transfers between organisms, and I think the whole area is about to explode."

Here is an interesting excerpt: "Subseafloor microbes are genetically distinct from life on Earth's surface and oceans. The Archaea the Penn State researchers found might look like bacteria, but they don't eat or work like them. While E. coli might double its numbers in 30 minutes, Archaea could take hundreds or even thousands of years to accomplish the same amount of growth."
