To reckon a living organism to a particular class, genus, and species is the work of systematic biologists. Biologists of the past (both before and after Darwin) found it easier to systematize the most highly organized representatives of the animal and plant world. But how to systematize, say, bacteria or viruses? In shape (stick, ball, spiral, crystalline)? By embryology (division of bacteria, self-assembly of viruses)?..
