WebAnd the fact that other Synapsids besides mammals had some derived mammalian traits isn't the result of convergent evolution, it's just that those features are common among Synapsids. A good example of this is how dinosaurs, pterosaurs, and crocodilians are all Archosaurs, and how they share many traits in common that defines that group. WebAfter they sort the homologous and analogous traits, scientists often organize the homologous traits using cladistics. This system sorts organisms into clades: groups of organisms that descended from a single ancestor.
