It is known in medical research as a model organism for studying the Duffy antigen. Nancy Ma's night monkeys have also been found to have an evolutionary pattern change in the hormone oxytocin. It was believed that all placental mammals had the same OXT amino acid chain until the discovery of a change in this New World monkey and others.^[4]
