Abstract
In 1974, John Cisne made two predictions concerning tagmosis in arthropods.
- 1.
The degree of appendage differentiation should correlate positively with measures of overall morphological specialization. Hence, taxa which diverge greatly from the ancestral condition would be expected to be more highly tagmatized
- 2.
The degree of tagmosis for higher arthropod taxa should reflect the complexity of their ecological role (but not necessarily reflect the ecological specialization of species within those groups)
