Their lead author, primatologist Marc Hauser, was dismissed from Harvard University after an internal investigation found evidence of scientific misconduct in his laboratory. Data supporting the authors' conclusion that cottontop tamarin monkeys displayed pattern-learning behavior similar to human infants reportedly could not be located after a three-year investigation. Women receive the majority of Ph.Ds in primatology. Londa Schiebinger, writing in 2001, estimated that women made up 80 percent of graduate students pursuing Ph.Ds in primatology, up from 50 percent in the 1970s. Because of the high number
