Some people say that humans evolved from the African lungfish. The reason is that this fish not only breathes with its cheeks, but also breathes with its lungs, but there is no scientific evidence for this statement, but there are individual self-media reports.
People on our side generally dig up crops in the field to eat, while Africans often dig lungfish in the field to eat, which is very drought-tolerant. In some parts of Africa, the climate is very dry, sometimes it rains only in years. Lungfish used to live in a place with water, because it did not rain for a long time, first in the water drought place to hit a mud hole, has been drilled in the hole to lie dormant, do not eat or drink, breathe with the lungs, until after the heavy rain and then reactivated.
In the absence of water, the longest survival record of lungfish is 4 years. Once an African farmer dug up a lot of mud in a dry pond in front of him and made an earthen house, in which a piece of mud had a lungfish built inside the wall. Exactly four years later, after a heavy rain, the African farmer's family was built with the lungfish inside the wall, breaking through the wet wall and following the stream formed by the rain back to the original pond.
