I think the more features two organisms share or the shared anatomical features, the closely related they are. For example; the class insecta (e.g bee, butterfly) and the class arachnida (e.g spider and tick) belong to phylum arthropoda because they have similar anatomical features such as appendages, segmented body among other features.
Due to the fact that they can mutate, they can adjust to many situations. If their environment changes and becomes colder for example, many other things will die but a virus can change to adapt to their new climate.
