Kenneth Kay Kidd is an American human geneticist and emeritus professor of genetics at Yale University School of Medicine. He is known for his work on the role of genetics in disorders such as manic depression and schizophrenia, on human genetic variation and its relationship to geography, and the Out of Africa theory of human evolution. He also helped discover the DRD4-7R gene that has been linked to exploratory behaviour. Kidd also did work on the forensic identification of individuals by single nucleotide polymorphisms and was a key figure in the 1990s Human Genome Diversity Project (HGDP), which indigenous populations rejected due to fear of exploitation of their genetic material, including for purposes other than medical research ("In the long history of destruction which has accompanied western colonization we have come to realize that the agenda of the non-indigenous forces has been to appropriate and manipulate the natural order for the purposes of profit, power, and control.").
