Summary: | Ancestor–descendant relationships (ADRs), involving descent with modification, are the fundamental concept in evolution, but are usually difficult to recognize. We examined the cladistic relationship between the only reported fossil pygmy right whale, Miocaperea pulchra, and its sole living relative, the enigmatic pygmy right whale Caperea marginata, the latter represented by both adult and juvenile specimens. Miocaperea is phylogenetically bracketed between juvenile and adult Caperea marginata in morphologically based analyses, thus suggesting a possible ADR—the first so far identified within baleen whales (Cetacea: Mysticeti). The Miocaperea–Caperea lineage may show long-term morphological stasis and, in turn, punctuated equilibrium. ... : Tsai and Fordyce 2014 ADR in Mysticeti supp 16Dec2014Tsai and Fordyce 2014 ADR in Mysticeti for fig1a and 1bTsai and Fordyce 2014 ADR in Mysticeti for fig1c and 1d ... |
