Formation of speech in the process of evolutionary development of man

How did human speech form during the evolution?

According to scientists, life appeared on our planet about three billion years ago in one of the most important habitats on Earth – in the water. The first living creatures were represented by unicellular microorganisms, for example, bacteria, and multicellular, such as fish with ciliated cells on the lateral lines performing tactile function. They worked, focusing on water fluctuations. Perhaps these creatures became the prototype of hair cells participating in structure the organ of hearing. Having developed enough in the water, after billions of years, living organisms emerged from the water and began to settle the land, and then the air.

Evolving and transforming, complex terrestrial creatures began to be divided into species groups: amphibians, birds, reptiles, mammals. Each species now had a hearing organ with sensitive hair cells in it. And, what is important, hair cells can function only in an aquatic environment. We see precisely this element in the structure of the human organ of hearing. But this is just a theory.

At pressure on these hairs a nervous impulse is generated, which is transmitted along nerve fibers. Sensitive cells clearly separate acoustic waves and send them to certain areas. In this case, a beam of different pulses is formed, which are transmitted along the auditory nerve to the brain.

He receives information and fonts it, that is, translates into voice. Consider the snail. This ancient structure in our body performs the function of hearing perception.


Today, these communication functions are distinguished:

  • Hearing;
  • Sound extraction;
  • Presence of an elementary language in animals;
  • The presence of a unique language in humans;
  • Acquisition of spoken language;
  • Opening access to cognitive thinking;
  • Formation of speech structures;
  • Creating a graphical reflection of speech.

Now we can say that our words can be formed not only in alphabetical layouts, but also expressed in gestures and on the letter, multisensory, and even completely break away from the peripheral sensory organs.

Hello. My name is Polina. Hearing once the truth that a pediatrician is the chief doctor for any family with young children, I realized that I have something to strive for.
