Tagmatization is the evolutionary process of

• A. Development of exoskeleton thickening.
• B. Merging larval and adult stages.
• C. Evolution of wings from leg segments.
• D. Grouping body segments into specialized functional regions.

Answer: (D)

Tagmatization refers to the fusion and specialization of sequential body segments into larger functional units called tagmata, such as the head, thorax, and abdomen in arthropods. This reorganization allows each region to develop a coordinated set of structures and functions suited to its role, improving feeding, locomotion, and sensory processing. The idea described here is about grouping body segments into functional regions rather than other changes like thickening of the exoskeleton, metamorphosis between larval and adult life stages, or the origin of wings from leg segments. Those describe different evolutionary or developmental processes, not the broad regionalization of the body.
