We invite you to meet the Bajau, the tribe that mutated and can submerge 60 meters under the sea. Some call them the nomads of the sea, since they live in an itinerant way. However, they always do it from the ocean.

A tribe that wades into the deepest waters
They usually build floating houses, as well as boats. Swimming is an essential part of their lives, the ocean being the essential supplier of their raw materials. For this reason, they usually dive many hours a day.
What is striking is the time they manage to stay underwater, as well as the depth at which they do so. In addition, they do it without extra implements. They just take a puff and drop into the water.
It is known that there are people with special qualities. For example, the Croatian swimmer Budimir Buda Sobat manages to stay 25 minutes underwater holding his breath. The Bajau achieve similar times, but at greater depth.
The key is in an organ that is different
Intrigued by the capabilities of these people, some researchers decided to study them. They got a surprise: the spleen is different in these people. Many believe that this genetic change is the cause of his underwater ability.
Some consider it an example of humans adapted to underwater life. They spend up to 6-8 hours in the water, so their bodies have developed a way to move in these conditions off land.
It happens that the spleen of these people can maintain a large amount of oxygen in the blood. In this way, it is possible to alleviate the absence of air by breathing. In addition, it allows you to maintain lucidity even when several meters submerged.
It is a genetic change. An adaptation that allows these people to be underwater for a long time. Undoubtedly, a possible sample of what evolution means is that of adaptation to circumstances.
Advantages for medicine and evolutionary studies
Research in this tribe has allowed us to establish that the spleen can be the solution in people with oxygenation problems. Also, an interesting example of the genetic evolutions of humanity.
The truth is that this discovery has delighted many people. Knowing that there are humans adapted to being underwater for longer is interesting. A living sample that evolution and genetics do not rest.

Are there other human groups with genetic variations? Undoubtedly, each human group adapts to its environment. It is something inevitable, but at the same time interesting to study.
