abstract = {{Kin recognition is a key ability which facilitates the acquisition of inclusive{\textless}br{\textgreater}fitness benefits and enables optimal outbreeding. In primates, phenotype{\textless}br{\textgreater}matching is considered particularly important for the recognition of patrili-{\textless}br{\textgreater}neal relatives, as information on paternity is unlikely to be available via{\textless}br{\textgreater}social familiarity. Phenotypic cues to both paternal and maternal relatedness{\textless}br{\textgreater}exist in the facial features of humans and other primates. However, theoreti-{\textless}br{\textgreater}cal models suggest that in systems with uncertainty parentage it may be{\textless}br{\textgreater}adaptive for offspring to conceal such cues when young, in order to avoid{\textless}br{\textgreater}potential costs of being discriminated against by unrelated adults. Using{\textless}br{\textgreater}experienced human raters, we demonstrate in a computer-based task that{\textless}br{\textgreater}detection of parent{\textendash}offspring resemblances in the faces of rhesus macaques{\textless}br{\textgreater}({\textless}br{\textgreater}Macaca mulatta{\textless}br{\textgreater}) increases significantly with offspring age. Moreover, this{\textless}br{\textgreater}effect is specific to information about kinship, as raters were extremely suc-{\textless}br{\textgreater}cessful at discriminating individuals even among the youngest animals.{\textless}br{\textgreater}To our knowledge, this is the first evidence in non-humans for the{\textless}br{\textgreater}age-dependent expression of visual cues used in kin recognition.}},
