Arthropod evolutionary biology

the grouping of an arthropod's serial body segments into functional regions such as head, thorax and abdomen.

Tagmosis is the grouping of an arthropod's serial body segments into functional regions, or tagmata (the insect's head, thorax, and abdomen, or the crustacean's cephalothorax and abdomen) so that a long chain of similar segments becomes a body of specialised zones. Hughes and Kaufman's 2002 review of Hox genes and the arthropod body plan shows how shifts in segment-identity gene expression remodel these regions across lineages, and Hughes's 2003 analysis of trilobite patterning traces tagmosis deep into the fossil record. The referent is the regional organisation of a segmented body, a central theme in how the enormously varied arthropods are built.[1][2]

Unit
The organisation of body segments into specialised regions (tagmata)
Recovery means
Not applicable
Measured by
Described by the number and segmental make-up of the tagmata and by the Hox-expression domains that define them
