Our price of living in community

We've known since the mid-20th century that our brains were smaller than in early humans, but a new study has uncovered exactly when that happened, and the finding is surprising and unexpected.

The researchers took on the task of cataloging as many human skulls as possible, 985 with their respective cranial capacities, from Miocene hominids, 10 million years ago, to present-day Humans.

After Analysis they found that growth in cranial capacity is slow for the first 8 million years and then accelerates to peak and plummet rapidly 3000 years ago.

3000 years a blink in evolutionary terms, a thousand years ago we already had sophisticated civilizations, commerce, metropolises, art, 3000 years ago the Great Pyramid of Giza was already 1500 years old and it was from there that our brains began to shrink rapidly, 50 times faster than before, in fact, the shrinking of our brains arguably coincides with the dizzying acceleration of our technological prowess, so evidently small brains don't have an impact on the general intelligence or cognitive abilities of the human, which sounds super contradictory but can have an explanation.

Humans and ants despite being very different animals have the greatest similarities in social terms, in both species there are castes, specialization and organization for the good of the community, even the two species practice agriculture.

To further explain this we take an example, the manufacture of a computer, I do not know how a computer works in its entirety or what components it requires, because it is an object that is too complicated, in fact, practically no one on their own knows how to manufacture one because each part I need people with accumulated knowledge, highly specialized and trained to design, manufacture and assemble each component of a computer.

Our tools have reached a level of sophistication that thousands of people with very specific knowledge and skills are needed to produce a single consumer object such as a computer. This is possible because it can be said that for more or less 3,000 years we have been able to of outsourcing knowledge in the form of language and writing, and distributing and storing it massively with tools such as the printing press initially and the internet today.

We do not need to know all those things that the ancient Human had to know, in a primitive environment because each person needed all the necessary knowledge to survive, in the present No.

Perhaps our intelligence, which is now more collective, has an effect on the size of our brains, as in ants, where collective intelligence and specialization produce a reduction or adaptive variation in the size of their brains, this has very interesting implications for the future. close, which is what our obviously accelerated evolution and our equally accelerated technological development that requires more specialization will produce in the coming millennia, of course assuming that other crises.

Humans of future civilizations will be as diverse and physiologically specialized as ant colonies and our brains will shrink to the size of a peanut, just to consume content and give likes? Only time will tell.
