Scientists have identified a critical step in the evolution of filter-feeding whales' enormous mouths.
There's a whale of a new display at the University of Michigan Exhibit Museum of Natural History, a leviathan that represents a scientific saga of equally grand proportions.
Whales are remarkably diverse, with 84 living species of dramatically different sizes and more than 400 other species that have gone extinct, including some that lived partly on land.
A U.S.-led study of the fossil of an extinct pregnant whale discovered in Pakistan suggests primitive whales gave birth on land.
