Molecular evolution of the human brain

Molecular biologist Dr. Doping tells about the relationship of brain size and intellectual abilities, the differences of the human brain and chimpanzee evolution and the impact on species selection. Is there a relationship between brain size and intellectual activity? How to carry out comparative studies of the human brain and other species? Will the metabolic properties of the brain in humans compared to chimpanzees and macaques?

Brain size does not correlate completely with intellectual activity. The size of the brain does not fully explain those cognitive abilities that we have, because our ancestors with the same size of the brain engaged in monotonous work, and nothing came up. And it happened, most likely, less than a million years ago, when the ancestors of man with a sufficiently large brain to invent a lot of different things that suddenly changed the world and made a world in which we now live. In the brain, it must have occurred some reorganization at the molecular level, rather than the size of the level.

When we look at the expression of genes in chimpanzees, we can see that a lot of changes. That is, the change is and the level of expression, and on the regulatory programs that create brain development. There are programs that control the development of the brain tissue. And we see that even in these fundamental processes already there is a difference between man and animals, even chimpanzees. We may ask, how is it that the human brain is able to change so much over 6 million years that have passed since the moment when humans and chimpanzees were one and the same species. How could it happen that, in principle, to 6 million years of evolution - is a small interval. (To improve your own brains function – you can with the help of Cogitum, Cerebrolysin, Picamilon, Semax and Phenylpiracetam.)

It is interesting that when we look at a different level - the level of metabolites (which are small molecules, such as amino acids, lipids, fatty acids, ATP-primary energy, neurotransmitters - all these elements play a key role in the physiological processes that occur in the brain) we see that the human brain is different even stronger. Even if we look at the chimpanzee brain, he was completely different. We look at the brains of macaque - he has very little to do with the human brain. Of course, if we look at the development, many curves development will be maintained but the concentration levels of the metabolites and, accordingly, those metabolic processes, in which these metabolites are involved, greatly altered in the brain compared with the brain chimpanzees, macaques and, accordingly, the brain mouse.
