#radiation.spreading  the spread of a group of organisms into new habitats
  subtype:  adaptive_radiation  the development of many different forms from an originally homogeneous group of organisms as they fill different ecological niches
  supertype:  natural_process__naturalproces__natural_action__naturalaction__action__activity  a process existing in or produced by nature (rather than by the intent of human beings); "the action of natural forces"; "volcanic activity"
     supertype:  process__proces  a sustained phenomenon or one marked by gradual changes through a series of states; "events now in process"; "the process of calcification begins later for boys than for girls"
        supertype:  phenomenon  any state or process known through the senses rather than by intuition or reasoning
           supertype:  process__proces__physicalsituation  intuitively, the class of things that happen and have temporal parts or stages; examples include extended events like a football match or a race, actions like pursuing and reading, and biological processes; sumo#process is not identical to pm#situation because an instance of pm#situation is not necessarily an instance of sumo#physical
              supertype:  situation  something that "occurs" in a real/imaginary region of time and space
                 supertype:  thing__something___T__t___3D_or_4D_thing_or_anything_else  any category (type or individual) is instance of this type; any type is also a subtype of this type
              supertype:  process_or_process_description
                 supertype:  processing_thing
                    supertype:  thing_playing_some_role  category to classify things according to roles/viewpoints; classification under this category is application-dependant
                       supertype:  thing__something___T__t___3D_or_4D_thing_or_anything_else  any category (type or individual) is instance of this type; any type is also a subtype of this type
              supertype:  physical__physical_thing  an entity that has a location in space-time; locations are themselves understood to have a location in space-time; click here for more details on the identical category sowa#physical_thing
                 supertype:  thing__something___T__t___3D_or_4D_thing_or_anything_else  any category (type or individual) is instance of this type; any type is also a subtype of this type
  supertype:  spreading__spread  process or result of distributing or extending over a wide expanse of space
     supertype:  change_of_location__travel  a movement through space that changes the location of something
        supertype:  movement__motion  a natural event that involves a change in the position or location of something
           supertype:  happening__occurrence__natural_event__naturalevent  an event that happens
              supertype:  event  something that happens at a given place and time
                 supertype:  process__proces__physicalsituation  intuitively, the class of things that happen and have temporal parts or stages; examples include extended events like a football match or a race, actions like pursuing and reading, and biological processes; sumo#process is not identical to pm#situation because an instance of pm#situation is not necessarily an instance of sumo#physical
