RE: Classification: A Definition
For the Monotremata example, Mammalia is a clade inside Synapsida, just as
Monotremata is a clade inside Mammalia. Thus, by extension, Monotremata is
a clade (one of many) inside Synapsida. The source of confusion for
Anthony Docimo, as far as I can tell, is that he is assuming that the word
"monotreme" is supplanted by "synapsid". This is conceptually incorrect.
actually, that wasn't what I was asking....I was reminded that not all
egg-laying mammals could be classed as monotremes -- so I asked if they
could be classed as synapsids. (as just calling them "mammals" would just
confuse some kids)
hope that clarifies things; thanks for the reference.
