"Langley's report against primate experimentation, "Next of Kin" (2006), was published simultaneously with the publication by the Medical Research Council and the Wellcome Trust in favor of primate experimentation.The "New Scientist" wrote that her report cited studies suggesting that macaques and other small monkeys are more conscious of themselves and others than was previously believed, giving them a moral status equivalent to that of great apes, who are currently not used in experiments in the UK.
