Among the earliest testimonials of human civilization is a deep intuition that some aspects of human behavior originate in our genetic makeup, while others feel like the result of upbringing or exercise. A central question posed by both ancient philosophers such as Aristotle and modern researchers in the twenty-first century deals with the impact of nature and nurture on human characteristics such as personality or intelligence. While Aristotle questioned how resemblances between parents and their offspring can be explained (Henry 2006), Sir Francis Galton (1869) as one of the first scientists already dealt in his famous work Hereditary Genius with the genetics of intelligence.
