“All three clades containing Prunum and “Volvarina” species contain⟳ morphological features that do not collectively appear⟳ in any other living or fossil marginellid species (see⟳ above).”

“No one has ever tabulated the number⟳ or percentage of non-trending clades within larger monophyletic groups. The concept of a non-trending clade — the higher level analog of a species in stasis — has never been explicitly formulated at all. If only one percent of clades exhibited sustained trends, we would still focus⟳ our attention upon this tiny minority in telling our favored version of the story of life's history.”

“A clade is made up of an ancestral species and all its descendants; think⟳ of it as that part of an evolutionary tree that would fall⟳ off with a single saw⟳ cut⟳.”
