Web increased evidence on whale evolution shows that modern whales diverged from ancient forms around 34 million years ago, with whale diversity peaking during the miocene epoch, 23 to 5 million years ago, and then decreasing until now. Early whales took advantage of abundant marine resources, feeding on the ocean's fish, squid and other larger food.
