An A to Z of science fiction fields of study.
This science is a given. Even if the story doesn’t involve alien ecosystems, a near or far future world is an undiscovered country of new manifestations of living things, human or otherwise. What have we so far found living on this planet? Plants, animals, fungi, bacteria, slime moulds, archaea. From synthetic to quantum biology the list of organisms that can be conjured up is endless.
