However, recent research reveals an interesting fact that makes us question this idea: The human brain shrinks over time!

Yes, you heard right. For thousands of years, The size of our brain is a small indicator of our intelligence. It was considered. Today, however, the opposite seems to be the case. But how?

The shrinking of the human brain over time is a topic that has preoccupied the scientific world for years.

Research on the human brain shows that the modern human brain existed 100,000 years ago. of the species Homo Sapiens This shows that it is almost 12% smaller. This situation raises only one question: why?

Some argue that the development of a way of thinking is called symbolic information processing suggests that it affects brain size. In other words, we might think that smaller brains can carry out more complex thought processes more effectively.

Our ancestors may have started using their brains more effectively over time with the power of thought.

Another theory is more interesting. Because this theory focuses on the consequences of climate change. Researchers think brain shrinkage may be linked to global warming.

Just like our body, so does your brain Being smaller can make it easier to stay cool. This can also be an adaptation to adapt to climatic conditions.

Nowadays, with the development of technology, tasks such as storing and processing information can now be performed using means outside the brain. A reduction in brain size may be unavoidable.

Naturally, the transition to agriculture and eating habits also have a major impact.

Food sources with the transition to agriculture It may have become more monotonous, which negatively affected the development of the brain, causing it to shrink over time.

The most important thing we need to understand from here is that brain size is not directly proportional to intelligence. Because research shows that having a bigger brain compared to body size doesn’t mean we’re smarter.

Why our brains shrink over time While we haven’t found a definitive answer yet, the fact is that many different factors will contribute to this process.
