In Galton’s phase of initial career, he made a smooth relationship with Darwin. They used to exchange their ideas and thinking about adaptation, diversity, creativity and much more. In their earlier part of dialogue Galton had his personal perception of evolution and inheritance that did not match with Darwin. But with the passage of time, Galton was convinced with Darwin’s idea of evolution and his concept of natural selection giving birth to adaptation. He then started to support Darwin in his ideas about diversity and adaptation because Darwin’s concepts had firm ground realities lying beyond. His thoughts revolved around natural selection which had its own strong convincing ability. But after Darwin’s demise, Galton was unable to deal with the measurement of diversity. The Galton’s version of diversity suggested that diversity refers to the differences among individuals dwelling in a pre-defined environment (Galton, 1869). Thus one of the major contributions of Galton in research of creativity is the definition of diversification in terms of individual differences. This idea proved to be very beneficial in further researches carried out by other scientists.
