Blow's hypotheses

Blow's hypotheses suggest that in humans and primates, certain brain regions—specifically the vomeronasal organ and associated neural pathways—are involved in processing social and reproductive behaviors, similar to mechanisms seen in animals with a strong sense of smell. These hypotheses propose that these structures influence how primates recognize kin, choose mates, and communicate socially, primarily through chemical signals. Essentially, Blow's ideas explore whether and how chemical communication impacts social interactions and reproductive strategies in primates, including humans, highlighting a potential biological basis for certain social behaviors mediated by these sensory systems.
