...BEEN CAPABLE OF SENDING EXtraterrestrial signals for only a minute fraction of the billions of years our planet has been habitable.

And the discovery of hot-water volcanic vents deep in the ocean, surrounded by rich ecosystems of exotic life, implies that a hot, young, volcanic planet might in fact be an ideal incubator...
