Researchers Find First Genetic Evidence for Loss of Teeth in the Common Ancestor of Baleen Whales
September 29, 2010
Biologists at the University of California, Riverside, provide the first genetic evidence for the loss of mineralized teeth in the common ancestor of baleen whales. This genomic record, they argue, is fully compatible with the available fossil record showing that the origin of baleen and the loss of teeth both occurred in the common ancestor of modern baleen whales.
