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 higher level grouping of a genetic haplogroup.
