The official theory of the origin of man in modern science is "savannah". Its idea is that our distant ancestor, a monkey, got down from the trees and went to live in the savannah. There he developed bipedalism (walking on two legs), a large brain and other nishtyaks. But why did our ancestor go to the savannah? Why couldn't he sit in the warm and familiar jungle? Where did the wool go? How and why did the brain develop? Why get up on 2 legs if 4 feet are much more comfortable to move around?
There are alternative theories of the origin of man, there are about 14 of them, this is bioengineering, and alien, and so on. and so on. But now we will talk about aquatic theory.Aquatic Ape Theory or the theory of the aquatic monkey (Hydropithecus). Like the savannah theory, it is just a hypothesis, but nevertheless it explains some aspects of human development much better than the official theory.
Hydropithek(Hydropithecus) - a hypothetical human ancestor, an amphibian monkey.
It was first proposed by the marine biologist Alistair Hardy in 1929, but published only in 1960 due to the fact that Hardy feared criticism from supporters of mainstream science, and, independently, by the German biologist Max Westenhoffer in 1942. But the most active and famous popularizer of the theory was the anthropologist and writer Helen Morgan.
So, getting out of the jungle, our ancestor went not to the savannah, but to the sea, river, lake. Swim and dive.
Here are some of the human characteristics associated with aquatic theory:
• If you open your eyes in water (without goggles), then when you emerge, tears help to clear the eyeballs of salt.
• Modern people can dive due to voluntary control of the breathing process. Moreover, people have a so-called "closing reflex" of the airways when immersed in water (this reflex is automatically triggered when water reaches the face)
• Ability to block the nasal passages. The muscles of the nostrils in humans work like valves, allowing you to partially cover the nasal passage, regulating the ingress of water into it during swimming.
• The windpipe is not far from the esophagus (low larynx). A similar design is found only in aquatic mammals (for example, seals). It allows you to control your breath, hold it and dive.
• The presence of pronounced eyebrows on a hairless face protects the eyes from water flowing down from the forehead when emerging.
• The presence of hair on the head, in the absence of it on the body, helps to protect it from overheating, since the head is always above the surface of the water in an aquatic lifestyle.
• The hairline in the armpits and groin area traps the pheromones secreted by the human body. In the absence of hair, the pheromones would be washed off with water, which would reduce sexual attractiveness and affect procreation.
• Humans lack hair, which is typical for large or non-arctic aquatic mammals (whales, dolphins, sirens, walruses).
• Human nostrils are directed downward, unlike other primates, whose nostrils are directed forward. This structure allows you to avoid water entering the nose when diving. Only one modern monkey has a similar nose - the nosy, which can swim, lowering its head into the water.
• Unlike other primates, the adoption of water procedures is not only pleasant, but also vital for humans, since it is due to hygienic requirements. For most primates, the water barrier is often insurmountable. One of the few exceptions is the nosy monkeys, which live in mangrove forests and never move away from the water. They are also characterized by downward nostrils and partial upright posture (when in water).The nosy monkey can dive up to 20 meters under water.
• The vital necessity of the human body in the consumption of iodine and sodium chloride (salt), found in abundance in seafood. The lack of iodine in the food consumed leads to thyroid disease.
• Possibility of full nutrition exclusively with seafood (eg Japanese cuisine).
• Presence of small webbing between the toes, about seven percent of people are born with webbing between the toes. Humans have a membrane between their thumb and forefinger - something that primates don't.
• Man has the longest penis of all primates. When copulating in water, this length ensures one hundred percent penetration of sperm into the vagina
• Presence of vernix caseosa, or primordial lubricant of newborn babies, also common in marine mammals, but not in monkeys.
• Only aquatic mammals mate face to face. The genitals in humans and aquatic mammals are located in the front of the body. Land animals mate in a position where the male is behind the female, mainly due to the fact that in the conditions of life on the ground surface, this position is the most stable and safe. The vagina in females of most primates and other land dwellers is located under the tail.
• Wide human palms, in contrast to the long and narrow palms of monkeys, allow you to swim perfectly, raking water with your hands
• Swimming and diving
• The human foot is functionally more like a flipper than a tree-climbing limb.
• The human foot has a flat and wide appearance and is adapted for walking in silt and sand.
• Long hair on the human head allows cubs to cling to them in the water. The rest of the primates have short hair on their heads.
• Waste water consumption by the body, which is extremely atypical for savannah animals
• A large amount of adipose tissue on the mammary glands is characteristic only for humans. This can be explained by the fact that milk had to keep warm in cold water. Female monkeys have small mammary glands and no adipose tissue.
• A person prefers to live or relax on the banks of water bodies. If a person is offered to build a house or spend a vacation in the savannah, jungle, deep forest or on the seashore, river or lake, the overwhelming majority will choose the shore of the reservoir.
• The disappearance of canines and claws, which is characteristic of aquatic mammals.
• Not a fear of water and fire, which is not typical for monkeys
• People have mastered stone tools, sea otters also use stone tools to get food: they use stones (up to 3.5 kg) to open hard mollusks.
• Eating fish and shellfish diets has a positive effect on brain development, since the brain needs phosphorus, which is abundant in seafood. Large brain
• The presence of a swimming reflex in a newborn, which is atavistic in a modern person
