Xeno-biology (part 4)


We are still making new scientific discoveries all the time, and sometimes find that our conclusions about something are wrong. New studies into the brain of the octopus, for instance, have shown unusual biological mechanisms at work that are unexpected, such as an ability to edit proteins at the synapse and spontaneously generate more complexity. Why then, if we do not fully understand all the biological mechanisms at work on our own planet, do we assume that we can understand what works on an entirely different planet? Should we assume that all life is carbon-based? Silicon-based life might also be possible, considering the similarities to carbon at the atomic level. There might even be other atomic structures out in space that we are entirely unfamiliar with, with elements entirely different from those that we have on earth. Although we certainly are able to recognize the components we are familiar with here on earth when observing the universe while using telescopes and other equipment, would we really be able to recognize and properly analyze something different if we came across it?
