These shared derived characteristics are called synapomorphies.
-
It cannot be defined by synapomorphies, as is the proper way.
-
If you mean using shared derived states (synapomorphies) to reconstruct phylogenies, this is used more for some kinds of characters (mostly morphological ones) than others (DNA sequences, for example).

I don't know if he still supports it, but no one else seems to: the proposed synapomorphies are either more likely to be plesiomorphies (J. van der Made, pers. comm.) or aren't convincing in view of the fact that basal hippos lack characters that unite suids and peccaries (Boisserie 2005).

The focus on cellular kinship has generally provided a more reliable basis for the classification of organisms than perceived homologies (or synapomorphies), but with regard to independent cells, organizations of cells, and levels of individuality, taxonomy remains almost entirely indiscriminate.

Is there really any reason to debate evolution with those who deny the importance of genetic and morphological homologies synapomorphies and vestigial organs?

Protophasmids miss critical synapomorphies (traits that identify a taxon) of Phasmida, and are currently considered probably close to Orthoptera (crickets and grasshoppers).

Still others 3 would divorce modern lungfish from porolepiforms proper, which renders your synapomorphies moot, and Kenichthys irrelevant.

I realise that some synapomorphies group Dipnoids with tetrapods, but my contention has always been that other groupings can be, and have been, defended.
