Why evolution for them? a super intelligence not granted?

Brains at first glance size is directly proportional to intelligence Even though it seems so, the truth is not so.

Relationship between brain size and intelligence

Yes, an elephant’s brain is much larger than a human’s. But it’s not just about brain size. Intelligence is not about the size of the brain, but how effectively it is used. There’s a key concept here: brain-body relationship.

Humans have a much higher brain-to-body ratio than animals. Good the size of our brains, It goes beyond meeting our body’s needs and gives us the ability to solve problems, learn languages ​​and think abstractly.

For example, an elephant’s brain weighs about 5 kilos, but most of this mass is normal control your body is spent. Those enormous ears, large trunks and large and small muscles are quite difficult to handle!

The human brain requires less physical control. this too complex thinking There is more brainpower left for you.

Not only brain size, but also the internal structure of the brain is an important factor that determines intelligence.

It is estimated that there are 86 billion neurons in the human brain. However, the number of neurons alone is not enough! Between these neurons links In other words, synaptic networks are the real source of the human brain’s superior intelligence.

Special the frontal lobe of our brain; It is responsible for our abstract thinking, planning and language skills. Even if animals have this region, they are not as developed as ours. There is no complex and powerful communication network between the neurons in their brains like ours.

Another important factor is social life.

People in a social environment They learn and develop. Since childhood, we increase our intelligence through information sharing, cooperation and language.

There is also a social structure among animals, but this structure is not as complex and knowledge-based as that of humans. For example, dolphins and elephants are social animals, but just like humans learning abstract concepts Their ability to transmit to each other is limited.

Finally, evolution does not always make intelligence a priority.

Elephants, dolphins or birds in different shapes to survive They learned. Some animals run fast and some survive with camouflage.

We humans have used our intelligence to become a dominant species in this world, but this does not mean that every species must follow such a path. So nature always the biggest brain or he does not choose the smartest; Sometimes the one who adapts best and finds the simplest solution wins.

Because humans are superior in these characteristics, those of the planet the most intelligent beings It is accepted as such, but this does not alter the fact that other animals are very successful in their own world!
