Brain capacity is also known as cranial capacity, the person’s cranial cavity volume of about 1500 ml.
In daily life, it is common to hear people ridicule each other for their brainlessness.Perhaps many people are curious, how big is the human brain capacity?Let’s find out together.
Details
01
When a person is in the mother’s body, the skull cavity is not fully developed. After the child is born, the skull is usually stuck in the back of the head, while the forehead is empty. The earlier the child’s skull is healed, the smaller the brain capacity.
02
From the perspective of the volume of the cranial cavity, the volume of the human cranial cavity is about 1500ml, while that of the great apes is only 400-500ml, and that of the Javanese ape is about 900ml. There is no systematic data conclusion on the brain volume of different races of modern humans.
03
From 1891 to 1892, a Dutch military doctor discovered the earliest fossils of human beings, including skulls, mandibles and thigh bones. Based on the skull found, the estimated brain size is only about 900 milliliters, much smaller than the modern human brain, but larger than the ape brain.

Scientists have been debating the question of whether a high IQ means a large brain capacity. Now, researchers have found that brain size does little to explain the problem of IQ. On the contrary, the structure of the brain may be the key to explaining IQ.
05
Scientists from a psychological research institute said: “At present, the data we have observed shows that the role of human brain capacity in human IQ testing is negligible.
