Why is it you are attracted to some people yet not others? Is it looks, personality, attitude...or could it be human pheromones at play?

Pheromones play a huge role in the animal world. My question to those who doubt their existence in humans is are we not part of the animal kingdom? For example, bees use pheromones as a means of communicating attack signals; spiders attract moths to their lairs by imitating the moth's pheromones; dogs know when there is an opportunity to test their sexual prowess when there is a female on heat in the area.

Pheromone pesticides have also been developed to combat known pests such as fire ants. Fire ants have an aggressive disposition and it's reasoned a pheromone based product can be effective in subduing this aggressiveness.
