Since ancient times, man has sought to explore the world around him. Scientists, philosophers and writers were driven by the desire to know the secrets of the universe and uncover the mysteries of nature. With the development of technology, it became possible to conduct large-scale scientific research, which expanded the understanding of our planet and opened up many new opportunities for humanity.
In the age of universal computerization, it is easy to get access to the information of interest. However, often a large amount of knowledge leads to the fact that little-known facts remain in the shadow of fundamental scientific research, which are important for broadening one's horizons. The following are interesting data from various fields of science.
A unique flow of evolution
The origin of our species is one of the major mysteries that science has yet to unravel. The following are facts little known to the general public:
- Man learned to speak due to the fact that approximately 350 thousand years ago his larynx, containing the vocal apparatus, descended into the throat.
- Scientists have proven that in primates, the growth in brain size is accompanied by an increase in teeth. The only exception is a person who does not have this pattern.
- One of the negative effects of the change in hip bones that allowed our ancestors to walk upright was that the lower back became more vulnerable to pain and injury.
- Little-known facts about a man who lived in a primitive era serve as the basis for modern research. So, it was proved that the unique skills of throwing stones and sharpened spears over long distances allowed our ancestors to successfully hunt and get food for food. Eating protein-rich meat stimulated the development of the body and brain. This information is essential for modern medicine.
- Humans burn approximately 50% fewer calories than most other mammals. A slow metabolism is responsible for the long lifespan of our species, unlike, for example, hamsters, dogs and cats.
