Besides, intelligence has always been caused curiosity in not only the psychology area but also in the neuroscience and biology area.

However, the long-standing argument about how nature and nurture affect intelligence still continue to invest by many psychologists. This means is which one is dominant to determine our intelligence genes or the environment. That’s why scientists mainly focus on what is the role of genes and the environment on intelligence.
Biology of IQ
Nature which represents genetics and many scientists thinks that our genes have a significant role in our intelligence. One of the biggest advocates of gene’s importance was Frances Galton and he published a book in 1869. Galton made an experiment about heritability working with twins. According to Galton our intelligence is based on our genetic background more than the environment. If people share similar genes, they tend to be in a similar…
