The differences consistently fell in areas near color genes in sections of the genome once considered junk. Scientists have since learned that these areas of the genome, which once appeared to have no purpose, can play crucial roles in regulating genes and modifying their effects. All other trademarks and copyrights are the property of their respective owners. What really fascinates him is how male capuchinos can look and sound very different across species, despite being almost identical genetically.
