The earliest proposed that humans originated from primates is the famous biologist Darwin, although at that time, people thought that Darwin was "talking nonsense", but in the following hundreds of years, with the deepening of research, the vast majority of researchers today also believe that humans did originate from primates, after all, a lot of evidence has been found.
But did humans originate on land or in the sea? There are still many researchers who argue about this issue. In 1960, the famous British anthropologist Arist first put forward the conjecture that "human beings originated in the ocean", Alist believes that in the history of human evolution, there are large gaps, and these blank periods are found on land, so it is very likely that they evolved in the ocean.
Arist believes that in the process of primate evolution toward humans, there was a stage of "sea apes", because in terms of time, about 4 million years ago, because of the rise in sea level, there were large areas of land in eastern and northern Africa that were submerged, so the apes that lived here at that time were very likely to go to the ocean to live, and after the sea receded, they chose to return to the shore again, and eventually evolved into human form.
<h1 class="pgc-h-arrow-right" data-track="4" > so, did humans really originate in the ocean? These 4 "evidences" are thought-provoking</h1>
The first "proof": the physiological characteristics of humans are more similar to those of marine mammals
Speaking of which, in the ocean, it is not that there are no mammals from land, whales, seals, etc., their ancestors first lived on land, and later for some reasons, they will evolve in the direction of marine mammals.
Through the comparison of physiological characteristics, in fact, human smooth skin and subcutaneous fat are closer to marine mammals, on the contrary, there is a great difference between them and primates that have evolved on land from beginning to end.
The second "proof": human tears are salty
In the ocean, the tears secreted by marine mammals are salty, this is because they themselves live in the ocean, and the sea water is salty, so after ingesting a lot of salt, in order to maintain the salt balance in the body, so marine mammals will secrete salty tears through the tear glands.
However, on land, only human tears are salty, and humans, as a member of primates, in fact, primates on land do not have this function at all, which has become one of the reasons for researchers to question.
The third "proof": Human babies seem to be born with a fondness for water
Studies have shown that if pregnant women give birth in water, then their pain will be reduced a lot, and this will also make pregnant women and fetuses feel more comfortable, at the same time, human babies seem to be born to like water, if you look closely, you will find that it seems that many babies are born to swim, which seems to mean that being close to water may be an instinct of human beings.
The fourth "proof": Humans seem to be more adapted to life underwater
Compared with animals that have evolved on land from beginning to end, humans can hold their breath in the water for a longer time after entering the water, especially when they diving, and their physical functions will become more like marine mammals.
<h1 class="pgc-h-arrow-right" data-track="22" > so, did humans really originate in the ocean? Some people have already done this in Southeast Asia</h1>
In Southeast Asia, there is a mysterious race, the Bajau people, who live on the ocean from the moment of birth, and unless they encounter a special situation, the Ba yao people will never set foot on land for a lifetime.
Therefore, some people believe that the Bajau people may be "returning to their ancestors", or that their ancestors themselves were some kind of special ancient humans who had been living in the ocean.
Speaking of which, in order to better live in the ocean, the Bajau people will choose to puncture their eardrums when they are young, and in the long run, for the future Bajau people, perhaps they will no longer need to pierce the eardrums, and they can live freely in the ocean like marine mammals.
In scientific research, scientists have also found that for the Bajau people, who have at least a thousand years of history, the genes in their bodies have mutated because they have never set foot on land, compared with normal humans (humans living on land), the genetically mutated Bajau people have super diving ability, which allows them to dive in the water for at least 5 hours a day, which is very incredible.
However, since the number of Bajau people themselves is not large, there are only about 400,000 people at present, so the study believes that even if the Bajau people are really evolving in the direction of "marine intelligent creatures", in fact, the main living place of human beings in the future will still be at sea, so, in your opinion, will the origin of human beings come from the sea?
