Neuroscientist and evolutionary biologist Justin Rhodes explains the difference between traits that are the result of evolutionary adaptation and others that are genetic spillovers. Rhodes discusses how biologist and author Stephen J. Gould first used an architectural term to help describe these genetic side effects.
Rhodes is a professor in the University of Illinois Department of Psychology, Neuroscience Program, Institute for Genomic Biology and a full-time faculty member in the Beckman Institute NeuroTech Group.
