This is very interesting but it doesn't prove anything. It doesn't prove any transitionals at all. Evolutionist like to point out that a creature exhibits a feature of another species and say see there is the transitional. What they don't do is point to all the other evidence that says that is isn't. But because a fish looks like its walking it can be used as an immediate visual proof that show a common feature between two different creatures. IE fish and land species.
First off if you want to talk science you need to learn the language of science. Nothing is ever "proved" . If you use that term there is no "proof" of anything including gravity. The proper term is evidence and we do have evidence of transitional species. When a hypothesis is first formed ways to test it and evidence that support it have to be found for it to advance. After a hypothesis passes its first few tests it is usually introduced to the scientific community as a whole. Eventually after thorough testing it may become a theory. The theory of evolution has been tested for 150 years and has not failed yet. It is accepted as "provisionally true. As are all other accepted theories.
The thing is they have not found definite proof and links with a fish and a tetrapod. They have speculated may different creatures because they have shown some similar features or they have shown some feature that can show the bone structure has changed. But many have had inconclusive proof in that there are only fragments of fossils such as a skull only or traces of foot prints that have not been found but who knows what it was. They like to speculate it was a link but all they have is foot prints and no carcass to verify it. The other thing is many of these creatures have parts that are not associated with fish at all but they still will focus on the legs as the main proof.
See there you go being unreasonable again. Scientists know that there is no "definite proof" of anything. And again you have to think, if an idea was wrong could it survive 150 years of people trying to show that it is wrong. Though you cannot prove an idea to be right, you can prove it to be wrong. For example the claim of a global flood is disproved from all sorts of approaches. One of my favorites is that of a population bottleneck. We can tell by the measured diversity in animal species that there was no flood 4,500 years ago, nor in the last 100,000 years, due to the diversity of the species of animals of the Earth:

Like your videos of the frog fish there are species which walk on the sea floor which shows that they dont need to come out of the water to do that. If developing feet was to come on land for an advantage then why do some have walking ability in the sea which is evidently their special advantage. The fish that have front legs and come out of the water are easily taken for dinner by the monitor lizard so what is their advantage. They would have been better off staying put in the water.
Sometimes yes. But there are environments where the predators are in the water, not on the land. And when the first tetrapods evolved the land was very safe. No predators at all were there to attack them.
There are ones like with the snake around with legs today. Are they in the process of evolving. So we should see the back legs coming soon. Out of all the fish or should i say Amphibians or reptile type water creatures have either complete front legs or complete 4 legs or a fully formed fin as the mud skipper has. I can never see a set of rear legs even starting to pop out or any legs disappearing. They are all complete fully functioning features.
All creatures are always in the process of evolving. But there is no definite "goal' to evolution except for survival. Anything that helps survival will be saved. And of course all features are "fully functioning". That is a rather foolish complaint. New traits evolve from old abilities. What happens is that a creature can always perform a range of functions. Some new ones arise at it evolves. If those functions are positive for survival they can become fixed in the genome of the population as a whole. For example it is not much of a change for a walking species to develop the ability to run. There would always be a range of walking speeds that different offspring had and if it was advantageous to be able to move more quickly the offspring that were faster would be more likely to succeed (pass on their genes). There offspring would have a range in speeds too, but since they were descended from the faster moving critters their offspring would also be faster than the old norm. In a few hundred generations all of them would be running.
I notice that the flat head looks similar to tetrapods in features and so does the crocodile in many ways. There is no reason why these are not a unique species that have unusual characteristics. But they are and always have been the same but with great variation.
Sure there are. Just because you cannot spot significant differences does not mean that the experts cannot.
There was a theory that the environment dried up and forced them onto land. But i would have imagined an easier way to adapt would have been to just go back to deeper water than grow legs and have all the changes for breathing and that. Besides if they were the first creatures to go onto land what did they eat. Why would it be an advantage to go onto a place with no or very little food. They say they sometimes ate each other but if thats the case its more or less killing themselves to survive. It just doesn't make sense. I wonder if they can do a DNA test to see where they actually came from. If they can check the coccoliths lookalikes they have found.
Why do you think there was no food on land? Even back then there were mosses and lichens and other such near plant life. Just think of it, a place safe from predators with a food source that no one else is eating. For an animal that is as close to heaven as you can get. Once fish started to make an incursion onto land the benefits for the ones that evolved was unlimited.
Just like the snake there is a lot is being made out of the legs. Even the evolutionist say its all inconclusive. But i have noticed how they go on about certain discoveries and make a lot out of them only to be refuted by a newer discovery which puts everything they have said up in the air again. I guess only time will tell or when they do some genetic testing.
Even so it still doesn't say that all this just like the snake isn't variation withing a creature that was designed to spend its life in and out and around the water edge just like the croc or the many that are around today.
Why are you concentrating so much on a family that there is little evidence of?
You need to remember the animals that we do have evidence of evolving strongly implies that all animals evolve.
Also the creationist side has no explanation besides "magic". They cannot explain the fossil record. They cannot explain nested hierarchies. and ERV's make their heads spin.
Why believe in something that not only has no scientific evidence supporting it, and has almost endless evidence opposing it?
