Mixed-race children are taller and smarter. Having genetically diverse parents it means being more intelligent than ancestors. Researchers from the University of Edinburgh analysed health and genetic information from more than 100 studies carried out around the world. These included details on more than 350,000 people from urban and rural communities. The team found that greater genetic diversity is linked to increased height It is also associated with better cognitive skills and higher education levels. However, genetic diversity had no effect on factors such as high blood pressure or cholesterol levels, which affect a person's chances of developing heart disease, diabetes and other complex conditions. Dr Jim Wilson, of the University of Edinburgh's Usher Institute, said: "This study uncover fundamental information about our evolutionary history. Answering questions first posed by Darwin as to the benefits of genetic diversity. Our next step will be to hone in on the specific parts of the genome that most benefit from diversity."
