Why Does Our Brain Get Smaller Over Time? – Webtekno

However, recent research reveals an interesting fact that makes us question this idea: The human brain is shrinking 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 as. However, today it seems that the opposite is the case. But how?

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

Research on the human brain shows that the modern human brain was 100 thousand years ago. from the species Homo Sapiens It reveals that it is almost 12% smaller. This situation raises only one question in mind: Why?

Some argue that the development of a way of thinking they call symbolic information processing suggests that it affects brain size. In other words, we can think that smaller brains can perform more complex thinking processes more effectively.

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

Another theory is more interesting. Because this theory focuses on the impact of climate change. Researchers think that brain shrinkage may be related to climate warming.

Just like our body, our brain also Being smaller can make it easier to keep cool. This may 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 done with resources outside the brain. Reduction in brain size may be inevitable.

Of course, the transition to agriculture and eating habits also have a great impact.

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

The most important thing we need to understand from here is that the size of the brain is not directly proportional to intelligence. Because research shows us that having a larger brain compared to body size does not mean being smarter.

Why our brains shrink over time Although we have not yet found a definitive answer, it is a fact that many different factors will contribute to this process.
