Further study by Mann-Esser’s team found a surprising commonality among the five percent of subjects showing clinical signs of susceptibility to evolutionary psychology, which the team refers to as “Desmond Morris Syndrome,” or DMS. Ninety percent of the DMS-positive subjects shared a single allele, first isolated by researchers at the University of Lucerne. The recessive allele, named luz-R, was absent from the remaining 95 percent of test subjects. (The corresponding dominant allele, luc-ID, has been tentatively linked to critical thought faculties and penis size.)
