Every child sooner or later asks his parents the question: "How did I come into the world?". It would seem that everything is extremely simple: conception, pregnancy, childbirth. But scientists have been trying for thousands of years to understand where the very first people came from. There are a lot of opinions on this subject, but each of us is familiar with the famous theory of evolution by Charles Darwin, the main idea of which is that man descended from apes. Today estet-portal.com proves this theory, talking about the main "evidence" of evolution - the rudiments in the human body. What are rudiments and why do we need them - read in this article.
Rudiments prove the theory of human origins
The rudiments are the clearest, simplest and most obvious proof of human evolution.
Rudiments or rudimentary organs are the structures of the human body that have lost their significance in the process of evolution. Such organs were necessary for people earlier in order to protect the body, help it adapt to environmental conditions, survive and produce offspring. But a person became smarter, made his living conditions more comfortable, and the need for rudimentary organs gradually disappeared. At the moment, such organs do not perform their function, but they are still present in our body.
How to find 5 characteristic rudiments in your body
The rudiments clearly demonstrate the difference between man and his ancestors. You probably didn’t even think about why there are such organs in your body:
Long palmar muscle
In the body of each of us there is a muscle that was necessary for our direct ancestors - primates. Finding it is easy: turn your hand palm up and close your thumb and little finger. On the skin of the wrist, a ligament is immediately contoured, which belongs to the long palmar muscle.
Our ancestors needed it, since it was this muscle that was responsible for extending the claws and allowing them to firmly grasp tree branches when jumping. Today, the long palmar muscle participates in the flexion of the palm, but this rudiment does not fulfill its direct function.
Goosebump
When we are cold or scared, goosebumps appear on our body. You will be surprised to know that there are hundreds of thousands of tiny muscles in your body responsible for hair lifting. This reaction of the body was needed by our ancestors, who had thick hair on the body - another rudiment.
The contraction of the muscles and the rise of the hairs made it possible to keep warm in the body, and in times of danger, the raised hair gave the animal a more intimidating appearance. Today, goosebumps are just another vestige.
Crescent fold
Look in the mirror: there is a small fold of skin at the corner of your eyes. Have you ever wondered why you need it? This fold is another rudiment, a remnant of the nictitating membrane.
Our ancestors needed it to moisturize and protect the surface of the eyeball. Today, the crescent fold is preserved in birds, fish and reptiles - the inhabitants of water and heaven. Modern living conditions have allowed a person to manage only two centuries, but the lunate fold in our body has long lost its function.
Wisdom teeth
But this unpleasant rudiment is familiar to very many people who have reached the age of majority. The unpleasant growth process of "eights", as we used to call these teeth in everyday life, causes considerable discomfort to a person.
The removal of wisdom teeth absolutely does not interfere with the chewing process, because these teeth were needed only by our ancestors, who were forced to chew tough and hard foods, such as raw meat. In the modern world, we consume almost all products only after heat treatment, so there is no need for wisdom teeth anymore.
Ear muscles
Another useless muscle in the human body is the ear. Some people have retained the ability to move their ears, and can amuse others with this spectacle. But today, only this function can be performed by the ear muscles, because our ancestors used them in order to better hear the approaching danger or prey.
In the modern world, the ear muscles are just a vestige, and the "talent of the chosen merry fellows" is nothing more.
The rudiments in the human body prove the theory of evolution, because besides them, even the smallest structures of the body play an important role for its correct and coordinated work.
