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 )
C’mon… didn’t anybody see this on Simpsons???
Oh my Science!
: )
It’s really not a news at all… It’s a long known thing…
They, as well as whales, are ’secondary’ marine animals. Which means they returned back to water in evolution. Ofcourse they didn’t look like todays dolphins with 4 legs glued on to them…
Other than the remains of their hind legs, and full pair up front, they also have lungs, and breathe air, not like fish and other ‘primary’ marine animals…
+the offspring
+everything about them really : )
