Other animals that have irreducible complexity are the seemingly simple ocean sponge, which scientists have discovered actually produces fiber optics better than our most sophisticated manufacturing methods. The sponge's thin glass fibers are capable of transmitting light better than industrial fiber optic cables used for telecommunication. Commercial manufacturing methods require high temperatures and produce relatively brittle cable that can crack if bent too far.
The sponge's fibers, grown at cold temperatures, are much more flexible, and can even be tied in a knot without breaking. By adding traces of sodium to the fibers, the sponge increases their ability to conduct light-something that cannot be done in commercial manufacturing. Scientists at Bell Laboratories hope to eventually learn how to duplicate the manufacturing process of this lowly sponge. Joanna Aizenburg at Bell Labs admitted, "Modern technology cannot yet compete with some of the sophisticated optical systems possessed by biological organisms." Most of us would think that an ocean sponge is a pretty rudimentary life form on the evolutionary chart, yet top scientists are trying to cope its sophisticated optical system!"
The sponge has complex systems. According to the journal Nature, there is an emerging field called biomimetics, in which scientists try to understand how biological systems are engineered and apply the principles to developing technology. Why can something that's "engineered," and that's more advanced than what scientists can create, couldn't have just happened by mindless, random chance processes?
