Furthermore, the absence of this replacement mode in the closest snake outgroups (Anguiformes and Iguania, sensu54), leads us to conclude that internal tooth resorption is a synapomorphy of Pan-Serpentes. Internal resorption can thus join the features characterizing snakes and can be used to ...
The Euglenida is a large group of marine and freshwater flagellates that contains more than 1,000 described species with diverse modes of nutrition, including phagotrophy (bacterivory and eukaryovory), osmotrophy (sensu stricto) and phototrophy [8]. The best synapomorphy for this group of ...
This unique shared derived character (synapomorphy) is not found in anyother Porifera groups. According to the last major morphological revision of theAstrophorida, five families are included in this order: Ancorinidae, Calthropellidae,Geodiidae, Pachastrellidae, and Thrombidae. To date, ...
Sasayamamylos is the oldest fossil record possessing the dental formula “3–4:1:4:3,” which is recognized as a synapomorphy of the Placentalia [8]. However, it is unlikely that Sasayamamylos is a member of the crown Placentalia because Sasayamamylos shared the several morphological ...
Another intriguing characteristic, which may be a synapomorphy of the subfamily (Clarke and Grebennikov, 2009), are the secretions of the larger set of their paired pygidial glands, that empty into the rectum and which, in addition to a defensive and anti-microbial function, can be squirted...
The minimum medi- olateral breadth of metatarsal IV is nearly 70 percent that of metatarsal I (a reversal of character 224 of Wilson30, regarded as a synapomorphy of the eusauropod clade Mamenchisauridae [ = 'Omeisauridae'] + [Jobaria + Neosauropoda] in...
You only need to learn three new words, autapomorphy, synapomorphy, and plesiomorphy. All of the other concepts (e.g., ancestors, monophyletic groups, paraphyletic groups) are familiar ones that were already part of Darwinian evolution before Hennig arrived on the scene. 展开 关键词: ...
1The notochord, a synapomorphy of the chordate phylum and asine qua nonof chordate development The chordate phylum is a large division of the animal kingdom that includes three subphyla of widely different organisms, ranging from marine invertebrate chordates, such as lancelets and sea squirts...
Forewing ScP short, ending on C at level of base of M + CuA and re-emerging distally as a faint phantom-vein ending on R (the fusion of forewing ScP with C is a character present in the other Archipsyllidae as putative synapomorphy, but it is re-emerging as a distinct vein ...
