Recently, a French medical scientist named Miguel Auden put forward a shocking point: the ancestors of human beings should be dolphins, not monkeys! Because humans and dolphins are more closely related than apes.
First of all, from the analysis of the two basic natures of animals, humans and dolphins like to eat fish, shrimp and seaweed, while apes don't; In addition, in the biological world, only humans have face-to-face sexual intercourse with marine mammals such as dolphins; The ape lay on his back.
More and more oceanographers have confirmed that dolphins make chimpanzees bow down in both "IQ" and "EQ".
Dolphin "tribe", draw friends and provoke enemies.
Of course, the most convincing thing is the scientific experiment. Australian scientists have followed several dolphin "tribes" for three consecutive years and found that in a large dolphin group, there are often several "hills", and most of the time they can "seek common ground while reserving differences" for common interests. But sometimes, if it is difficult for several "hills" to reach a "consensus", the dolphins in one "hill" will turn some tough and brave male dolphins in other "hills" against each other by bribing and alienating each other, and then form a new and stronger "joint fleet" to deal with or subdue other "hills" on both sides.
Sometimes, dolphins and tuna will form a temporary "mutual aid group" in order to round up mackerel more effectively. Once this cooperation is not needed, the partnership will end on its own. This means that dolphins are very "snobbish". Every dolphin is wondering who is an ally and who is an enemy at any time and place-if you must be friends, you must be wooed, even if it is hypocritical; But if there is no use value, then either kick it away or stay away.
Scientists have analyzed that it is the pressure brought by the repeated "alternation" of cooperation and competition with peers or "foreigners" that accelerates the evolution of dolphin brains to complexity. Just as human beings have gradually evolved in a social state where relatives, friends and enemies are mixed together, dolphins have also learned to be snobbish in the struggle, and to be snobbish, they need enough wisdom as a "backing"! Therefore, scientists say that the formation of dolphin "wisdom" is similar to the process of human intelligence maturity!
According to animal experiments, dolphins have "self-awareness".
American scientists confirmed through a recent study that dolphins may have "self-awareness". We should know that "self-awareness" represents a highly developed intelligence and is one of the important signs that distinguish human beings from other animals. At present, scientists have confirmed that apart from humans, only primates such as gorillas have "self-awareness".
Children are born without "self-awareness". Generally, you can't recognize your image in the mirror until you are one and a half years old, and "self-awareness" begins to appear. This is because, as far as memory is concerned, the working efficiency of dolphin brain is second only to that of human beings, and it also has a superb sonar system that human beings do not have, which eclipses the naval sonar system.
In order to prove whether dolphins or other animals have "self-awareness", animal psychologists at new york State University have designed a unique "mark test" method. The specific method is: paint the experimental animals with a pigment, and then let them look in the mirror. If you deliberately look at the color sign left on yourself after seeing the image in the mirror, it is considered to be showing "self-awareness".
Most animals who accept the "test" will ignore their own image in the mirror, or mistake it for another kind and fight with it (such as rooster). Only primates such as orangutans, chimpanzees and gorillas will check their bodies with mirrors, thus passing the "sign test".
In addition, among non-primates, only dolphins with marks on their bodies swim to the mirror repeatedly, constantly turning over their bodies and looking at their stains through the mirror, showing signs of "self-awareness". What puzzles scientists is that the brains of primates and dolphins went through different evolutionary paths about 6 million years ago, but dolphins reached or even exceeded the intelligence level of primates.
Contact signal, dolphins can call them by their first names. In the face of danger, dolphins have amazing ability to distinguish.
No matter on the surface or underwater, dolphins can tell whether the approaching ship is a dangerous fishing boat or a passenger ship without danger.
Dolphins living in the Caribbean seem to have mastered the laws of local fishing boats casting and collecting nets. As a result, they no longer blindly avoid fishing boats, and sometimes even deliberately meet them. Of course, all dolphins, including young dolphins, will not swim to the port side of the fishing boat, because they have long known that the trawl is pulled to the deck from the port side by winch or crane, but the starboard side is definitely a "safe area" without bloody disasters.
The most interesting thing is that some clever dolphins are already trying to compete with fishermen. Japanese scientists found that once a fishing boat opened its net, some dolphins swaggered into the net with silly tuna. Before closing the net, the dolphins were still desperately preying on the mackerel in the net, as if unaware of the coming danger.
Fishing boats have begun to close their nets, but dolphins are still keen on food and fight for it. It turns out that they have long known that if they want to get fishing boats out of the net, they must have a back row. At this time, the edge of the net near the port will sink into the water for about 20 seconds-they are full of food and drink, waiting for this wonderful opportunity energetically: just wait for the edge of the net to sink, and they will rush out of the net like flying arrows. After all the dolphins have successfully rushed out of the encirclement, they will happily perform several beautiful high jumps not far from the fishing boat, as if demonstrating to angry fishermen!

Manage smarter like a dolphin.
Inspired by the wisdom of dolphins, Dr. Dulle, an American economic management scientist, put forward a management model-"dolphin management". "dolphin manager" is a transformational manager. They firmly believe in their own value and judgment of the future, so they dare to swim to the waters where no one has swam, in order to achieve the goal of breakthrough.
In contrast, the so-called "shark managers" think that every small part of the market should not be lost, but should be "greedily" won, so they are just busy expanding their scale and occupying market share all day. This strategy is just playing an endless game where they want to eat but can never eat each other. It seems that not only natural scientists but also economists are impressed by dolphins!
