The human brain has shrunk by 150-200 g over the last 25,000 years (that's about -12.5% of the total mass). There are two opinions. One says that the mass has become smaller, but its design has been updated and the connections between neurons have become more complex. Thus, a person has become smarter. Others say that our ancestors were much smarter than the average person of the present generation. They explain this by the fact that in the past it was necessary to be comprehensively developed for survival, and now all tasks are delegated. You don't have to make a pen yourself or fix a water pipe if you have to: you do video editing, for example, or solve math, delving only in one direction, while thousands of other people are making pens, extracting oil to make plastic, and so on. Our population is much larger than it used to be and we are winning in quantity, not quality.
What opinion do you hold yourself?))
