We have recently reported that both dolphins and elephants may be self-aware beings, like humans. Scientists think that dolphins and whales, which live in the water despite breathing air, evolved onto land, but then RETURNED to the water, because they liked it better there. Now scientists may have found a missing link that proves this theory of evolution?just as we’ve recently discovered a human missing link.
Japanese researchers captured a bottlenose dolphin that has an extra set of fins that could be the remains of hind legs. Fossil remains prove that 50 million years ago, dolphins and whales were land animals that walked on four feet.
