Why does intelligence level of person differ from each other?

Why does intelligence level of person differ from each other?

Summary: Differences in intelligence have so far mostly been attributed to differences in specific brain regions. In intelligent persons, certain brain regions are more strongly involved in the flow of information between brain regions, while other brain regions are less engaged.

Why do humans have higher intelligence?

This hypothesis posits that human cognitive complexity arose as a result of the higher level of social complexity required from living in enlarged groups.

What is the difference between artificial intelligence and natural intelligence?

The key difference between the two is that artificial systems are designed whereas natural systems are evolved.

Is there a difference between race and intelligence?

Once there are genetic differences between races, there will be intellectual differences, it is impossible that it is otherwise. There are also race differences in the brain, both quantitative and qualitative. Cavalli-Sforza’s analyzes in molecular biology confirm the subdivision of the human species into a dozen of main clusters.

Is there a difference between human intelligence and other animals intelligence?

We humans are animals, in fact primates, but there is certainly a difference between human intelligence and other animals intelligence. Just count the number of human individuals and compare it with the number of other primate individuals; the difference is huge.

[According to evolution, all the life in earth were arise from simple DNA. First it started as a single cell as an unicellular organism and later evolved into complex multicellular organism.

Is intelligence genetic or environmental?

I.Q and Human Intelligence Intelligence is an highly genetic factor. 85\% of intellectual variations observed are genetic variations. The remaining 15\% is determined by the so-called « non-shared environment », which is essentially the prenatal environment, childhood diseases and the nutrient environment in early childhood.
