The study on twins can help us understand the nature vs. nurture controversy, because 2 individuals who have the same DNA, but are brought up in 2 different environments allows us to compare and contrast the twins' intelligence. If there are any differences in the twins intelligence, we can blame that change on the environment (nurture), which proves that intelligence is based on genes. However if they both continue to have the same intelligence levels, that proves that intelligence is hereditary.
