Well I have to correct myself somewhat. If you are talking about a REALISTIC zombie scenario .. there sense of smell would only be as good as you or me. They wouldnt GAIN any super sense of smell. In Realistic scenario, I believe it iis simply just deemed as an instinct to identify the living. If all they hang around and smell is rotting flesh, when a live person finally does come by.. i think your toast

Again if your talking a REALISTIC scenario, then the only possiblity is they are initially infected with a virus that mutates the brain. Killing the person and shutting down many functions of the body. The only explaination for them to have any motor skillz and that feeding inclination is that your instinctive functions are not destroyed by the brain mutation.
