If Charles Darwin's theories about evolution are still questioned, the Salamander fish is one of the living animals that proves his theories ...
This fish currently has several species distributed between Australia, South America and East Asia, revealing that it may have remained close to its ecosystems for more than 300 million years as the same continents, once together, were separated.
It has lungs, which makes it unique on the evolutionary scale, from where its aquatic congeners have external gills unlike these. This allows it to spend a couple of hours out of the water in the shallows of rivers, and even thanks to the shape and strength of its fins, crawl and almost crawl like snakes on the banks of rivers and mangroves landward.
It is one of the fish with a bone system similar even to vertebrates such as humans. And certainly this unique position among its other marine peers, together with its ability to flirt with the mainland, outside its marine environment reaffirms the theory that nature always makes its way to adapt the fittest to changes in climate or geography, as well as their food sources.
One of the current concerns is the danger of extinction that it is facing, since the environment in which it lives feeding on mollusks, is increasingly reduced.
Did you know why being human has evolved how are we today? Because we are the most adaptable, and because we even adapt the environment to our needs. The question that we have, as a last thought, is whether we can continue to adapt the environment to us, or if we should flow with it? We believe that we are wiser than nature and millions of years of evolution?
