Evolution of the Human Brain

Anthropologist tells about the australopithecines, the pace of development of the brain lobes. How the brain of Australopithecus was arranged? What are the changes in the environment it has been associated key point in the evolution of the human brain? How develop certain proportion of the human brain? And as the power system affects the brain development of animals?

The weight of the head is a determining factor in changes in brain size, because the head pressure on the spine, and the same size of the body the head should be one and the same mass. Accordingly, the jaws decreased and brains grew rapidly, we can observe turtles. Furthermore, the meat does not want to tend to be eaten, it resists. It is more difficult to find it, catch it, convinced that it should be eaten. Accordingly, it is necessary to exert greater intelligence.

To improve your brain you can by the help of Phenotropil, Nootropil, Picamilon GABA, Semax and Cerebrolysin.

The occipital lobe modern man is responsible for the perception and recognition of visual images. That is to say that we are aware of what we see. In fact, we see a lot more than you realize. Why it has decreased - this is a big question. occipital lobe may be partially responsible for something else, besides the view. Maybe what is now engaged in the parietal lobe, was characteristic of the occipital lobe, too. Maybe our ancestors recognition of visual images was much more important than for us. People living close to nature. They need to recognize the dangers of predators, some other phenomena and do so very quickly. We now it is not so important.

The man was herbivorous, and thus become a little predator. Strictly speaking - omnivorous. But while he has long been a hands free. He used tools. And when he went to eating meat food, he did not have large fangs and claws, it was not until this predator. He had to adapt to this way of employment. Why go and technological progress. The first stones were for scraping the meat off the bones, because tear meat hands and teeth of herbivorous essentially impossible. The combination of many individual factors led to the fact that a person wiser. And other animals have evolved in the same direction, they did not have such zigzags in evolution, so they stayed who they were.
