This is the blog for GW students taking Human Evolutionary Genetics. This site is for posting interesting tidbits on: the patterns and processes of human genetic variation;human origins and migration; molecular adaptations to environment, lifestyle and disease; ancient and forensic DNA analyses; and genealogical reconstructions.

Is face recognition heritable?

Face recognition, the ability to recognize and memorize faces, is one type of specific cognition that is often thought to be correlated with general cognition. A  recent article on PNAS that studied both identical and fraternal twins in the UK tested face recognition using Cambridge Face Memory Test (CFMT) along with object recognition test and general cognitive ability supports previous studies and indicates that face recognition is substantially heritable due to genetic influences that are highly specific to this ability. The study also notes that although correlated with object recognition and general cognitive abilities, face recognition is genetically independent.
