Currently, the theory is quite popular that some intelligent life is possible under water. Experts are studying the oscillations of the satellites of the gas giants, suggesting that there are entire oceans somewhere below the surface. Theoretically, it is from there that UFOs can fly to Earth, which ufologists constantly repeat.
Also, some experts say that if in the distant future something happens to our planet, then it will be possible to try to move to some of the satellites of the same Saturn or Jupiter. Naturally, you will not have to live on the surface, given the large amount of various kinds of harmful substances there, as well as extremely low temperatures. Experts believe that people could drill some area and sink into the subsurface ocean.
However, how likely is it that humanity will turn into mythical amphibians? There are many stories that there may be creatures that are similar to humans, but have fins, a tail, and so on, living, respectively, in the water. This plot is quite popular in art. Quite a lot of books and films on this topic, including the new blockbuster "The Shape of Water".
According to the latest research, amphibian humans can really only stay at the level of cinema and print stories. A paper presented by experts in the Department of Earth Sciences at Stanford University in California provides evidence of this. Experts emphasize that it is usually considered that it is much easier to live in water, there are fewer restrictions, and so on. However, in fact, the body is not so relaxed there, but very great pressure affects it.
It is also strongly influenced by the fact that it is colder in water than on land. To keep warm, you need to adapt in your own way. Mammals that live in water are quite large, and their shape is oblong. It is enough to remember whales and dolphins. Experts also cite the example of dogs and hippos for comparison. These creatures have an ancient relationship, but one can appreciate how different they are in appearance. It was the life of hippos in the water that influenced this difference.
Mammals need large sizes to keep warm in such an environment, since the temperature there is much lower than body temperature. Metabolism also increases, so losing weight in water is simply not possible. Accordingly, amphibious people in the form in which many imagine them are simply not possible. In the same way, if there are intelligent beings somewhere in the subsurface oceans of the satellites of the gas giants, then if they are mammals, they are still completely non-humanoid. In general, life underwater comes with a number of other limitations. That is why, although life was born there, however, the exit to the surface was associated, among other things, with the fact that there are easier conditions here.
