PHYSICAL ANTHROPOLOGY: Hereditary Genius: An Inquiry into Its Laws and Consequences. F rancis G alton

Abstract

Galton believed that his data on hereditary genius support purely genetic inheritance. On the contrary, analysis under a simple model shows no clear resolution of genetic and cultural inheritance in this material, or generally, unless adoptive relations, monozygous twins, and/or environmental indices are included in a design adequate to test the assumptions under which they are informative.
