Why is our response to other people enhanced by nudity? In other species with eyes, their visual response is enhanced by olfactory/pheromonal input.
Sex on the brain: a fear of pheromones
A flying mammal that relies on acoustic signaling for food acquisition helps make my case for the importance of olfactory/pheromonal input during the development of sexual preferences.
Pheromones are more important to the behavior of species from yeasts to you. Remember this if you plan to celebrate Valentine’s Day.
If, as is frequently stated, humans have a reduced sense of smell compared with other species, we should be unable to recognize and differentiate among olfactory/pheromonal stimuli from other humans.
