广泛存在的证据表明，当亲属住在一起时，亲属关系在塑造社会行为的演变方面发挥着核心作用。以往的研究表明，雌性恒河猴（Macaca mulatta）识别熟悉的母系亲属使用声音线索。然而，由于恒河猴雌性在可能的受孕期内滥交交配，很可能隐藏了父系，因此识别父系亲属可能更加困难。行为观察表明，半自由放养的雌性恒河猴更喜欢与他们的父亲同父异母的姐妹在同一组内的无关的女性相比，特别是当出生在同一年龄组。然而，在父系亲属歧视中使用的线索和机制仍然存在争议。在这里，我们调查了雌性恒河猴是否使用声学模态来区分父系同父异母姐妹和非亲属，并测试了熟悉性和表型匹配的潜在机制。我们发现，测试女性更经常回应的父亲同父异母姐妹的电话与无关的女性的电话相比，这种歧视能力是独立的呼叫者和测试女性，这提供了，据我们所知，声学表型匹配的第一个证据之间的熟悉程度。我们的研究加强了雌性恒河猴可以识别其父系亲属的证据，并且发声被用作线索。
Widespread evidence exists that when relatives live together, kinship plays a central role in shaping the evolution of social behaviour. Previous studies showed that female rhesus macaques (Macaca mulatta) recognize familiar maternal kin using vocal cues. Recognizing paternal kin might, however, be more difficult as rhesus females mate promiscuously during the possible conception period, most probably concealing paternity. Behavioural observations indicate that semi free-ranging female rhesus macaques prefer to associate with their paternal half-sisters in comparison to unrelated females within the same group, particularly when born within the same age cohort. However, the cues and mechanism/s used in paternal kin discrimination remain under debate. Here, we investigated whether female rhesus macaques use the acoustic modality to discriminate between paternal half-sisters and non-kin, and tested familiarity and phenotype matching as the underlying mechanisms. We found that test females responded more often to calls of paternal half-sisters compared with calls of unrelated females, and that this discrimination ability was independent of the level of familiarity between callers and test females, which provides, to our knowledge, the first evidence for acoustic phenotype matching. Our study strengthens the evidence that female rhesus macaques can recognize their paternal kin, and that vocalizations are used as a cue.
