Interesting discovery of ancient animal species

While the aestheticist looks at the beauty candidates under the rings 1, 2 and 3, the scientist pays attention to the evolutionary ability of people in the . round neck. This part has been shown to be the most variable in the evolutionary process so far, both in humans and animals.

Extremely interesting facts about ancient animals

It can be affirmed that the neck of mankind is one of the most evident evolutionary parts. Without it, people will not be able to walk on their feet, the brain will not be the size it is today to help us reap the intellectual results. In the course of evolution over millions of years, our ancestors went straight to their backs thanks to two key groups of the spine , the group of cervical and lumbar vertebrae and the lumbar and sacral vertebrae. Our heads are in balance with our bodies thanks to the complete neck with 7 vertebrae.

On the other hand, after millions of years, the human brain has undergone rapid changes to accommodate living conditions, from a mass of 600 cm3 in Homo habilis , to 1,200 cm3 in Homo erectu s and now to 1,500 cm3 in Homo sapiens .

However, compared to the stock of other animals in the evolutionary process to adapt to harsh living conditions, it seems that we must accept a humble position.For instance, when swallowing a chicken egg, their neck works as a jaw , the thorns inside the neck extend out in combination with the muscles in the neck vertebrae crushing the eggshell, pushing the substance. translates in the egg into the digestive tract, retaining the egg shell by a spasm. To achieve this achievement, the snake's neck must go through millions of years of evolution.

In aquatic life, fish have no neck . 370 million years ago, vertebrates and four limbs began life on the ground. To adapt to the new environment, the first amphibians had a joint germ between the skull and the first dorsal vertebra. Conquering the terrestrial environment is accompanied by the necessary evolution of the respiratory system.

According to Jean Pierre Gasc, professor of anatomy at the Natural History Museum in France, in the frog species , the air they breathe through the nose goes straight to the oral cavity. They only swallow prey and not chew, and must swallow quickly, because when swallowed they must hold their breath.

In reptiles , the situation improved: a palate pushed the air into the throat, to a gas tube next to the esophagus. In lizards , the neck grows, some of the lumbar vertebrae turn into cervical vertebrae . Since then, this part has been constantly transformed to suit living needs as more and more species appear on the planet. Many types of turtles have their necks as long as a snake's neck, which helps them not to raise themselves from the water when swimming.

Sarcoramphus papa vulture.

The Amazon vultures have the scientific name Sarcoramphus papa, which was originally conceived for a bit of furry necks, when their heads were tucked into rotting animals, their hairs were not stained with stains and stink, it was difficult to clean. . This bright red neck is also the most visible sign when they are flying over forest trees, looking down below and recognizing that the fellow is gathering around a bait. In morse species (Odobenus rosmarus), their necks have two airbags that can inflate or collapse freely. This opens the windpipe, allowing the male to stick his head out of the water to breathe in case of injury or merely to take a nap. When animals reach adulthood, the upper air sacs also act as resonators to send love signals to their children.

Alouatta senjculus monkeys.

Also in the instinct to communicate, call the monkeys , the neck of the screaming monkey (Alouatta senjculus) can startle the coldest of the most calm, because their screams resound to 2 km of jungle. The mystery of this strange ability lies in a piece of bone in their necks. This part can swell like a balloon, amplifying the sounds coming from the trachea , making them one of the most pronounced species in the animal world.

Chlamydosaurus kingii Australia lizard does not shout loudly to show off masculine power. Whenever they need to conquer their children, they stretch their skin around the neck with a diameter of up to 30 cm, looking like an umbrella. The wider their mouth, the wider the umbrella. The secret of this ability lies in the cartilage branches associated with their tongue and jaw muscles.

Snake neck stork .

Also in the butterfly village, like flirting and looking for partners, ostriches have a 1-meter-long neck that grows on a 2.7-meter-tall body. If we make a comparison to correspond to this species, the head of our species must be as high as a hand raised straight up into the sky. An ancient piece of ostrich species contains 18 vertebrae, which is their optimal performing medium in performances with partners.

Besides species that use antiquity as a means to conquer fellow human beings, some species aim for more practical needs, namely hunting and eating . The snake-neck stork (anhinga) has a S-shaped curved neck and is long, making it possible to rotate its head 270 degrees to observe its prey, speeding up the mine as an electric current to catch fish are swimming in the water.

However, the most worthy of the long ancient village is probably the giraffe. At a height of 2.5 meters from the foot on the shoulders and the neck of 2 m long, they have the condition to eat the leaves at altitudes that no one on the ground reaches. But every time they drink water, their heads have to bend down to a depth of 4.5 meters and there is a risk of blood flooding their brain. It was the neck that saved them: each time they had their heads to drink, the small valves were inside their necks, preventing blood from falling to their heads. When they finish drinking and raise their heads, the brain is at risk of not getting enough blood. This time the savior is the heart. This part creates a blood pressure twice as high as other animals, ensuring that the amount of blood pumped to the head meets the brain's requirements.

Just enough to show that the sophistication in the physiological structure of many species deserves to be human envious.
