I thought this interesting
Now here is a question. Since this is DNA based, what is the likely hood of crafting life that feeds on radio waves instead of light? Or that communicate with radio waves with an electric eel organ and antennas?
I think its very possible, and it's likely if there are in fact intelligent species out there, and they tend to be mechanical in nature both for computational reasons and hardiness, then they may very well love radio waves given off in the natural world. Such species can be seen in Gregory Benford's work.
