Biologists at the California Institute of Technology (Caltech) have identified the origin of olfactory nerve cells, finding that neural-crest stem cells – multipotent, migratory cells unique to vertebrates that give rise to many structures in the body – play a key role in building olfactory sensory neurons in the nose.
Insect odorant receptors regulate their own sensitivity.
The discovery of a neural pathway in the brain of an insect that has been linked to pleasure eating could shed new light on the impulsive consumption of food by men and women, claim researchers from one US university.

The evolutionary hypotheses of nose development in humans propose that noses are alterations of the angles of the skull because of bipedalism. Because of the change in diet that has come with modern time and the change of...
