About

Dr. Catherine M. Kemper is a leading paleontologist and marine mammal biologist whose work has fundamentally reshaped our understanding of baleen whale evolution. Her research centers on the functional morphology and evolutionary relationships of mysticetes, with a particular focus on the enigmatic pygmy right whale (*Caperea marginata*). Her most-cited study (2023, 6 citations) challenges over a century of morphological dogma by demonstrating that the skim-feeding strategy of *Caperea* is not a shared ancestral trait with right whales, but a striking case of convergent evolution. This finding resolves a long-standing phylogenetic puzzle, revealing that *Caperea* is more closely related to rorquals and gray whales than to the Balaenidae. Dr. Kemper’s work integrates comparative anatomy, fossil evidence, and feeding ecology, providing critical insights into how dietary specialization drives morphological adaptation in whales. Her contributions have been instrumental in clarifying the tree of life for one of the ocean’s most iconic groups, and her research continues to influence studies on cetacean evolution, conservation paleobiology, and the functional constraints of filter feeding.
