A 'pivotal' moment for understanding whale evolution

Scientists could soon better investigate the feeding behaviors of extinct dolphin and whale species. A third year student at Japan's Nagoya University has found that the range of motion offered by the joint between the head and neck in modern-day cetaceans, a group of marine mammals that also includes porpoises, accurately reflects how they feed. The authors of the study, published in the Journal of Anatomy, suggest this method could help overcome current limitations in extrapolating the feeding behaviors of extinct cetaceans.
