This feature was considered a synapomorphy
of Jobaria + Neosauropoda by Wilson (2002) and Mamenchisaurus + Neosauropoda (Carballido et al.
One possible synapomorphy
for the tribe is an absence of obvious leaf surface striations, since across this tribe striations have only been observed in some species of Stenocarpus (Carpenter, 1994).
The presence of anterior ventral glands (character 10, state 1) may represent a non-ambiguous synapomorphy
for all salamanders to the exclusion of the Sirenidae, while the presence of posterior ventral glands (character 11, state 1) was recovered as the ancestral state for the Salamandroidea with a subsequent loss (character 11, state 0) on the branch leading to the Amphiumidae.
Therefore, the assessment of whether the low chromosome number is a synapomorphy
of the clade or an autapomorphy of the specimens determined by Maury as B.
Hence, they have dimorphic anthers that are a diagnostic synapomorphy
for a complex composed entirely of American species.
Hypermineralized tooth plates are one of the most important synapomorphies of Holocephali, and the presence of one pair of tooth plates in the lower jaw and two pairs in the upper jaw is a synapomorphy
of Chimaeriformes (Didier, 1995).
hair is a synapomorphy
of mammals; Loss of the hind limb is a synapomorphy
of snakes) systematics--the branch of biology concerned with using evolutionary and phylogenetic principles to organize classification systems and to understand the origin and maintenance of biological diversity taxon--a formally-named group of organisms taxonomy--the scientific discipline concerned with discovering, naming, and classifying taxa
a shared SINE integration represents a synapomorphy
(derived state that is identical by descent) in contrast to a nucleotide sequence which may be identical simply by state (e.
Yoshizawa and Saigusa (2001) proposed another potential synapomorphy
, the fork of the anterior axillary fold-line of the forewing, a character that is independent from that one of the mouthparts, which reinforces the monophyly of Hemiptera.
In this study, a synapomorphy
is a species that is present in two or more endemic areas, and an autapomorphy is a species exclusive of one area.
We propose this morphological condition as another synapomorphy
for this widely recognized group.
Thus, we suggest that this feature is a synapomorphy
for the E.
