The British scientist Francis Galton, a cousin of Charles Darwin, coined the term 'nature versus nurture'. He became interested in the matter of heredity after reading Darwin's work 'The Origin of Species', and he wrote a book 'Hereditary Genius: Its laws and Consequences' in 1869. He observed that many clever and talented people seemed to produce equally or more gifted offspring, and he carried out twin studies to determine how people with the same genes might develop in intelligence when raised in the same environment or in different environments. He also studied intelligence levels between people of different races. His research led him to conclude that heredity or nature made more of a difference than environment or nurture, and that intelligence had to be inbred, it couldn't be trained. He then proposed that the arrangement of judicious marriages between gifted individuals...
