  1. I don't know what hypothesis we are talking about, but in general it is true that the brain's capabilities increase if evolution goes in this direction. But the trick here is that evolution has no purpose, which means that it does not have to go in the direction of increasing the capabilities of the brain. The advantage of natural selection is not given to the most intelligent organism, but to the one that is best adapted to the environment in which it lives. Sometimes this means improved brain capabilities. Sometimes-improved muscle capabilities. And sometimes-improved ability to resist the immune system of the host organism. It all depends on the specific species and its specific habitat conditions.

    And if we talk specifically about the person and his brain capabilities, then over the past 50,000 years, they most likely even decreased. The brain of a modern person processes information better, but it is much less creative in comparison with an average “caveman”. A relatively recent experiment is known, when archaeologists tried to create an obsidian one (I'm not sure, I don't remember exactly) a knife based on Stone Age technologies. As a result, the result did not even come close to the characteristics of a fossil find. And these are archaeologists! That is, people who have specifically studied these finds, who know the whole theory from and to. Today's average person simply cannot master this Stone Age technology – the modern brain is no longer able to create in this direction.

    On the other hand, a representative of that era in our information-filled world would also be very poorly oriented, even if some clever technology allowed him to be born in our time, and not just suddenly teleport here from his cave.

    Who's smarter here? You can't tell right away. It all depends on the environment.

  2. According to the research of Prof.Savelyeva S. V., who studies the evolution of the brain in the structure of WOUNDS our brain does not develop, but degrades. What we see daily supporting evidence for.

  3. Unfortunately, this is not the case. The brain capacity of a modern person is less than that of a conventional Cro-Magnon. Moreover, the average brain volume is slowly shrinking from millennia to millennia. The explanation is simple: specialization. A modern person specializes in one thing, and the rest of the knowledge that is needed at the moment is obtained from books, reference books, and the Internet. He does not have the task of keeping all knowledge to himself. But the ancient man had such a task. Almost any member of the tribe knew everything that the tribe knew, it was a condition of survival. All knowledge was passed on by word of mouth and by example, and the repository was one – the human brain. And the amount of knowledge required by the tribe is colossal. All information about animals and plants, methods of hunting, gathering, use of prey, production of tools, clothing, utensils, methods of treating wounds and diseases, principles of survival, knowledge of the terrain, enemies and their weaknesses… It is unlikely that at least one modern “civilized” person can put such a volume of information in his head. Degraded, easy to live steel.:)

  4. the brain of modern man is not the same as at the time of the appearance of modern man .. the brain lost about 300 cubic centimeters in volume (according to archaeologists)..

    the reason for this is the self-domestication of man .. any domesticated animal species loses in intelligence and brain size, as they lose the need for a number of basic functions related to survival and food production, etc.

    people who live in social groups and have a sedentary lifestyle, turn themselves (or each other) into pets .. some people call it “specialization” (kind of less offensive).

    and to our great regret, brain volume matters for the species as a whole .. and the loss of volume for humans means a reduction in a number of abilities, and the INABILITY to return to the wild, as with any pet.

    well, today, with the invention of the Internet and various gadgets, there is a chance that people will lose another 400 cubes unnoticed .. since some of the brain functions will be replaced by the functions of devices… and it will be impossible to return to these (newly lost) functions as well.

  5. Hello! Very interesting question! The brain is a complex biological device, an organ consisting of many interconnected cells and processes. If you imagine all the connections in the brain as a single line, it would be 7-8 times longer than the distance from the Earth to the Moon. The brain in human evolution not only increased, but also changed in the ratio of different parts! It changes over the course of evolution, as well as over the course of life as you learn. But especially surprising changes occur in extreme conditions for humans. In the course of evolution, the complexity of the brain, the number of its departments, parts increased, and because of this, its weight increased.

    The average brain volume of a modern person is about 1,400 cubic centimeters, which is quite a large amount for our body size. What is most interesting is that the size of the brain varies quite a lot among modern people. So, it is known that Ivan Turgenev's brain weighed 2012 grams, and Anatole France almost a whole kilogram less — 1017 grams. But this does not mean that Turgenev was twice as smart as Anatole France. Moreover, it was recorded that the owner of the heaviest brain — 2900 grams-was mentally retarded.

    But now scientists from Cambridge have come to the conclusion that the evolution of the human brain has ended, so we will no longer become smarter.. Studying the structure of the human brain, they came to a shocking conclusion: the evolution of intellectual abilities, which lasted several million years, has now reached its peak. And so in the foreseeable future, people will not be able to become smarter.: this is physically impossible.
