• Resumen

  • The current idea is that the ancestors of baleen whales lost their normal teeth and only later evolved a sieve. But the skull of a previously unknown species of whale suggests alternatively that they started filter feeding by adapting teeth to act as sieves. The 30-million-year-old skull was found on the bed of South Carolina's Wando river by a scuba diver about a decade ago. It has now been analyzed and described by a team led by Jonathan Geisler at the New York Institute of Technology.
