Bilaterality

Bilateral symmetry is two-way symmetry that is characteristic of many living organisms, including humans. It means that both sides of the body have the same structure and function, and also that they are symmetrical about the central axis of the body.

Bilateral symmetry can be observed in animals, plants, and even some bacteria. For example, in humans, bilateral symmetry is manifested in the structure of the face, arms and legs. It also manifests itself in the arrangement of organs such as the heart, lungs and kidneys, which are located on one side of the body.

In addition, bilateral symmetry plays an important role in brain development. Research has shown that the brain develops more efficiently when it is surrounded by a symmetrical environment. This may explain why many animals have bilateral symmetry.

However, not all living organisms have bilateral symmetry. Some animals, such as insects and reptiles, have an asymmetrical body structure. This may be because they live in a different environment that requires more attention on one side of the body, such as for hunting or protection from predators.

In general, bilateral symmetry is an important aspect of biology and development of living organisms. It helps us better understand how our bodies work and what factors influence brain development.

Progression and evolution on the planet occur through the development of living organisms. Before they appeared, living organisms went through a long evolutionary path and were able to retain the useful characteristics of their ancestors. All this gradually changed their external structure. Over thousands of years, evolutionary changes have modified many representatives of the fauna. Some of them became dangerous to other living organisms, others helped them survive. Now the body is one of the most difficult formations on our planet to study. The human body has a bilateral structure. It includes two important factors - one of the large parts of the body consists of two symmetrical elements, like the right and left arm or leg. From another point of view, these organs have the same structure. How did it all start? Life on our planet began about 3.5 billion years ago. At that time, chemical substances were formed that, under the influence of favorable radiation, created the first cell. This is how the incredible journey of biomatter on Earth began. She managed to adapt to various conditions of the globe. This is how life appeared. Until now, scientists do not know who the brain is, which “makes” the body move and performs many functions. There is no answer to this question. Each organism is structured interestingly and individually, since all living things were formed naturally. We are born with
