first proposed that humans originated from primates. It was the famous biologist Darwin. Although at that time, people thought that Darwin was "speaking nonsense", but in the following hundreds of years, accompanied by research Going deeper, most researchers nowadays also believe that humans indeed originated from primates. After all, a lot of evidence has been discovered.
However, did humans originate on land or in the sea? There are still many researchers arguing about this issue. In 1960, the famous British anthropologist Ariste first proposed the conjecture that "human beings originated in the ocean". Ariste believed that there are large gaps in the evolutionary history of mankind, and these gaps Evidence cannot be found on land, so it is very likely that it evolved in the ocean.
Ariste believes that in the process of primates evolving toward humans, they have experienced the " sea ape" stage, because from the time point of view, about 4 million years ago, because of sea level rise, In eastern and northern Africa, large tracts of land were once submerged. Therefore, the apes who lived here at that time were most likely to live in the ocean. After the water receded, they chose to return to the shore again and eventually evolved into humans. Looks like.
So, do humans really originate in the ocean? These 4 "evidences" are thought-provoking
The first "evidence": human physiological characteristics are more similar to marine mammals
Speaking of which, in the ocean, it is not that there are no mammals that come from land. Whales, seals, etc., their ancestors lived on land for the first time. Later, for some reasons, they evolved towards the direction of marine mammals.
From the comparison of physiological characteristics, in fact, the smooth skin and subcutaneous fat of human beings are closer to marine mammals. On the contrary, they are the primates that have evolved on land from beginning to end. But there is a huge difference.
The second "evidence": human tears are salty
in the ocean,The tears secreted by marine mammals are salty. This is because they live in the ocean, and seawater is salty. Therefore, after ingesting a large amount of salt, in order to maintain the salt balance in the body, so , Marine mammals secrete salty tears through their lacrimal glands.
However, on land, only human tears are salty. As a member of primates, in fact, primates on land do not have this function at all. This has become One of the reasons why the researchers questioned.
The third "evidence": human babies seem to be born to like water
Studies have shown that if pregnant women give birth in water, their pain will be much lower, and it will also make pregnant women And fetuses feel more comfortable. At the same time, human babies seem to like water by nature. If you look closely, you will find that many babies are born to swim. This seems to mean that being close to water may be a human instinct. .
The fourth "evidence": Humans seem to be more adapted to life under water
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 people are diving, their body functions will become more like marine mammals.
So, did humans really originate in the ocean? Some people have already done this in Southeast Asia
In Southeast Asia, there is a mysterious race-the Bayao tribe. These people live on the ocean from the moment they are born, unless they encounter special circumstances. Otherwise, the Ba Yao people will never set foot on land for a lifetime.
Therefore, some people think that the Bajao people may be " returning to the ancestor ", or their ancestors themselves are some special ancient humans who have been living in the ocean.
speaking,In order to live better in the ocean, the Bayao people would choose to puncture their eardrums when they were young. This will evolve over time. For the future Bayao people, perhaps they will no longer need it. By piercing the eardrum, you can live freely in the ocean like marine mammals.
And in scientific research, scientists have also found that for the Bajau people who have a history of at least a thousand years, the genes in their bodies have also mutated because they have never set foot on land. Compared with normal For humans (large humans living on land), the Bajau after the gene mutation has super diving ability, which allows them to dive deep in the water for at least 5 hours a day, which is very incredible .
However, due to the fact that the Bajau people themselves are not many, there are currently only about 400,000 people. Therefore, the research believes that even if the Bajau people are really evolving in the direction of "marine intelligent creatures", In fact, the main place of human life in the future will still be on the sea. So, in your opinion, will the origin of human beings come from the sea?
