The osphradium, a chemosensory organ on or near the gills, is a putative potential synapomorphy of Mollusca. Although the osphradium regularly appears on illustrations of hypothetical unifying molluscan bauplans, the homology of these putative sensory structures has been debated in most classes. ...
Which synapomorphy renders the mammalian clade monophyletic? That is, what characteristic appeared in the evolution of mammals that makes this group of species share a common ancestor, most likely with that characteristic. a. Presence of canine tooth b. M ...
What is the difference between a symplesiomorphy and a synapomorphy? Synapomorphy: atrait share by 2 or more taxa and their most recent common ancestor. Symplesiomorphy : A characteristic shared by 2 or more taxa also found in their earliest common ancestor. ...
placing Coleopterida outside a clade comprising the other examined holometabolan insects. This result coincides with one of the classical morphological points of view [3,83,84], some nuclear evidence [77], and with morphological and nuclear combined analyses [...

heterogeneous mixture model (CAT) under a Bayesian framework, currently implemented in software PhyloBayes [38,56], to substantially avoid the LBA artefacts. We show for the first time that the reconciliation between mitochondrial and previous nuclear and morphological knowledge is possible in the ...
Appendix A Morphological, behavioral, and host characters of Allocorynina used in the matrix in Appendix B. (1) Labial palp: (0) 3 segments; (1) 2 segments. The presence of 2-segmented labial palps is a synapomorphy for the Notorhopalotria-Rhopalotria clade. (2) Mean male rostral ...
