You don't need a specific organ to have a reaction to chemical signals. A pheromone is just a chemical the body creates, and an external body responds to. That response can be due to smell, taste or even touch. No special organ is needed for any of those.

Yes..... you do? That would be like saying you don't need a nose to smell, or taste buds to taste.

No. Pheromones are chemical messages that trigger specific behaviour or developmental changes in an external body.

That response can be due to smell, taste or even touch. No special organ is needed for any of those.

Smells and associations attached to smell are not the same thing as pheromones. In certain mammals and reptiles pheromones are received by the vomeronasal organ.

You're trying to make pheromones out to be something not supported by the definition. Pheromones are chemicals created in one body, that have an effect in someone else's body.

Dictionary definition:

a chemical substance that is usually produced by an animal and serves especially as a stimulus to other individuals of the same species for one or more behavioral responses

Lol, the merriam Webster dictionary is not an appropriate source to define the scientific understanding of a word or term.

The biggest difference between a pheromone and an odorus compound is that pheromones have an Innate purpose and odors have responses learned through association.

By your understanding of the word pheromone the sulphuric odor in fart could be defined as a pheromone..
