Dolphins may have WALKED the earth?
My world has been turned on its head lately. First the T-Rex may have actually been a bird, Pluto is no longer a planet, and now dolphins may have once WALKED the earth!
Japanese researchers said Sunday that a bottlenose dolphin captured last month has an extra set of fins that could be the remains of hind legs, a discovery that may provide further evidence that ocean-dwelling mammals once lived on land. [...]
Fossil remains show dolphins and whales were four-footed land animals about 50 million years ago and share the same common ancestor as hippos and deer. Scientists believe they later transitioned to an aquatic lifestyle and their hind limbs disappeared.
What’s next? Humans evolved from monkeys ( :-P )
