320 Evolution? The Fossils Say YES!
of these “transitional” walruses are on display at the San Diego Natural History Museum,
only a short drive from the original ICR headquarters. Gazing at them in the display case is
one of the most powerful proofs that transitional forms are real. We will see an even better
transitional series when we examine whales in chapter 14.
