Olfaction and human kin recognition
TLDR
Close biological relatives share somewhat similar odor signatures (presumably resulting from genetically mediated similarities in bodily biochemistry and metabolism) that could facilitate kin recognition.
The neuronal substrates of human olfactory based kin recognition
TLDR
The neural substrates of human kin recognition are mapped by acquiring measures of regional cerebral blood flow from women smelling the body odors of either their sister or their same‐sex friend, demonstrating that humans have an odor based kin detection system akin to what has been shown for other mammals.
Rats assess degree of relatedness from human odors
Partner’s body odor vs. relatives’ body odor: a comparison of female associations
: People positively appraise odors of individuals who are genetically different from themselves. Here we analyzed the relationship between perceived similarity of body odor to the judges’ relatives
Human Body Odour Individuality
TLDR
It seems that despite the stability of olfactory cues, the hedonic quality of body odour may vary over time.
Discrimination Between Individual Body Odors Is Unaffected by Perfume
TLDR
It is found that there are no differences in conditioning success between perfumed and unperfumed body odors, suggesting that perfume does not mask individual differences and that olfactory stimuli may modify social perception in other modalities.
Body odor similarity in noncohabiting twins.
TLDR
It is shown that odors of identical twins (but not dizygotic twins) can be matched by human sniffers at rates better than chance, even when the twins are living apart, indicating an important genetic influence on body odor and the potential for developing technologies for human odor printing in relation to underlying genotype.
Entangled chemosensory emotion and identity: Familiarity enhances detection of chemosensorily encoded emotion
TLDR
It is demonstrated that familiarity subconsciously sharpens one's sensitivity to chemosensory emotional cues, which increases as a function of the time couples have spent together, and provides insights into the mechanisms and interplays of chemOSensory emotion and identity processings.
Do Trained Dogs Discriminate Individual Body Odors of Women Better than Those of Men? *
TLDR
It was found that dogs trained for the study identified individual women’s hand odors more accurately than those of men, and it was hypothesized that this is either because of differences in chemical compounds making discrimination of women�'s odors easier, or because of greater “odor attractiveness” of women's scents to dogs.

Genetic Component of Bee Odor in Kin Recognition
TLDR
The primitively social sweat bee, Lasioglossum zephyrum, blocks the entry into its nest of most conspecifics from other colonies through a genetically determined odor coupled with a learned component by which guard bees discriminate between odors of close kin and other bees.
Signature Systems and Kin Recognition
TLDR
A model that predicts the necessary information capacity of a signature system is developed and tested, and the measured information capacity corresponds well to the prediction and is substantially greater than that of the homologous call of the similar but non-colonial rough-winged swallow.
Human olfactory communication
TLDR
Two experiments are done to determine whether adults can identify an individual and determine his or her sex by the odour of an article of clothing, and to examine whether an infant can identify its mother's odour by a behavioural response.
Interest of mice in conspecific male odours is influenced by degree of kinship
TLDR
The data suggest that the olfactory preferences of female mice are consistent with the hypothesis that early learning provides the yardstick by which unfamiliarity is judged, and that this system may have an important role in assortative mating.
