Cliff-edged fitness functions and the persistence of schizophrenia
Behavioral and Brain Sciences 27 (6):862-863 (2004)
| Abstract | Strong recent selection for social cognition may well explain the persistence of genes that predispose to schizophrenia. The specific mechanism responsible may be a skewed fitness function in which selection pushes the mean for advantageous mental traits perilously close to a “fitness cliff” where the system fails catastrophically in some individuals. | |||||||||
