A Small Step for Lungfish, a Big Step for the Evolution of Walking

The African Lungfish is being studied by University of Chicago scientists and have seen something truly remarkable. The lungfish is able to take its fins and "walk" on the bottom of a tank. This fish is being recorded by camera's and has shown that it can do this feature plenty of times. Scientists are amazed and are reporting on how much this helps the evolution of walking on land. By just looking at the bones of an African Lungfish, scientists would most likely dismiss this idea, but with this proof, it is almost impossible to throw away. Read more about the African Lungfish:

I found this article really fascinating. I guess I always thought that eventually in the process of evolution, creatures just sort of "sprouted" limbs gradually to be able to walk on land. This finding suggests that their bodies didn't sprout limbs, but they adapted themselves to use their fins to walk. It's cool to see an animal using what it's already got to adapt to it's environment, whether it was by accident that they learned to walk or intentional. It adds a new perspective.
I wonder how long they've been researching the lungfish, and how long it took for them to see evidence of walking?
This article also reminded me of this amazing "Mimic" octopus, which intentionally changes it's shape to adapt to it's camoflauging needs. It's pretty cool!http://www.youtube.com/watch?v=H8oQBYw6xxc
