An unusual species of fish that can walk and breathe air shows that these animals may be more capable of adapting to life on land than previously thought, researchers say.
The new findings may help explain how the ancient fish ancestors of humans colonized the land.
The evolution of the ancient fish that switched from living in water to living on land about 400 million years ago is one of the most pivotal moments in the history of the animal kingdom. These first four-limbed animals, known as stem tetrapods, ultimately gave rise to amphibians, reptiles, birds and mammals.
Just how ancient fish made the shift to terrestrial life still remains largely a mystery. To learn more about what happened, scientists investigated the bichir (Polypterus senegalus), a modern African fish that has lungs for breathing air, and stubby fins it can use to pull itself along on land. The bichir possesses many traits similar to ones seen in fossils of stem tetrapods, the researchers said.

Makes me wonder if on another planet, the fish never left the water and evolved down there into sentient beings like our selves..But under the water.
Then it makes me wonder if they could make machines that travel through water and air, or even space
Then I go onto thinking, I wonder if in their space crafts they have water to be able to live.
Then, what if they are here and living in our oceans in the deepest depths..
Anyway I'm pretty high. Thanks for sharing - I love # like this

Is this that 'frakenfish' that people thought would eat children?
The snakehead is what I'm thinking of that eats kids and puppies and bunnies.

I wonder if a Creationist would consider this fish a transitional species? Probably not.

To Study Evolution, Scientists Raise Fish That 'Walk' on Land

I thought I'd pop in and post this story. I think this is cheating but still interesting. One could imagine this development taking place in nature.
Here is a video on the topic

The majority of creationists will conveniently ignore this, and this thread.
I brought this species up to a creationist a few months back, he replied; "That's not evolution, God must have created them like that, and we simply haven't found them til now"
He also said "did you know they found seashells on top of Mount Everest?" (ref Noahs arc)
I didn't bother explaining plate tectonics and how the continents collided, I just chose not to speak to him again.
